Being provably secure means that the scheme comes with a proof showing that the existence of an efficient adversary against the scheme implies that the underlying hardness assumption is wrong. LPN based schemes are appealing for theoretical and practical reasons. On the theoretical side, LPN based schemes offer a very strong security guarantee. The LPN problem is equivalent to the problem of decoding random linear codes, a problem that has been extensively studied in the last half century. The fastest known algorithms run in exponential time and unlike most number-theoretic problems used in cryptography, the LPN problem does not succumb to known quantum algorithms. On the practical side, LPN based schemes are often extremely simple and efficient in terms of code-size as well as time and space requirements. This makes them prime candidates for light-weight devices like RFID tags, which are too weak to implement standard cryptographic primitives like the AES block-cipher. This talk will be a gentle introduction to provable security using simple LPN based schemes as examples. Starting from pseudorandom generators and symmetric key encryption, over secret-key authentication protocols, and, if time admits, touching on recent constructions of public-key identification, commitments and zero-knowledge proofs.","lang":"eng"}],"author":[{"orcid":"0000-0002-9139-1654","first_name":"Krzysztof Z","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","scopus_import":1,"corr_author":"1","conference":{"location":"Špindlerův Mlýn, Czech Republic","end_date":"2012-01-27","name":"SOFSEM: Current Trends in Theory and Practice of Computer Science","start_date":"2012-01-21"},"date_updated":"2024-10-09T20:54:42Z","alternative_title":["LNCS"],"publist_id":"3407","quality_controlled":"1","intvolume":"      7147","date_created":"2018-12-11T12:02:15Z","year":"2012","citation":{"mla":"Pietrzak, Krzysztof Z. <i>Cryptography from Learning Parity with Noise</i>.

WSTS are an attractive target for formal analysis because there exist generic algorithms that decide interesting verification problems for this class. Among the most popular algorithms are acceleration-based forward analyses for computing the covering set. Termination of these algorithms can only be guaranteed for flattable WSTS. Yet, many WSTS of practical interest are not flattable and the question whether any given WSTS is flattable is itself undecidable. We therefore propose an analysis that computes the covering set and captures the essence of acceleration-based algorithms, but sacrifices precision for guaranteed termination. Our analysis is an abstract interpretation whose abstract domain builds on the ideal completion of the well-quasi-ordered state space, and a widening operator that mimics acceleration and controls the loss of precision of the analysis. We present instances of our framework for various classes of WSTS. Our experience with a prototype implementation indicates that, despite the inherent precision loss, our analysis often computes the precise covering set of the analyzed system."}],"ec_funded":1,"file_date_updated":"2020-07-14T12:46:05Z","date_published":"2012-01-01T00:00:00Z","has_accepted_license":"1","ddc":["000","005"],"fulldoi":"https://doi.org/10.1007/978-3-642-27940-9_29","_id":"3251","status":"public","oa_version":"Submitted Version","day":"01","publisher":"Springer","acknowledgement":"This research was supported in part by the European Research Council (ERC) Advanced Investigator Grant QUAREM and by the Austrian Science Fund (FWF) project S11402-N23.","year":"2012","citation":{"ieee":"D.

First, we show how to specify the objectives of the participating agents, the trusted third party (TTP) and the protocols as path formulas in Linear Temporal Logic (LTL) and prove that the satisfaction of the objectives of the agents and the TTP imply satisfaction of the protocol objectives. We then show that weak (co-operative) co-synthesis and classical (strictly competitive) co-synthesis fail in synthesizing these protocols, whereas assume-guarantee synthesis (AGS) succeeds. We demonstrate the success of assume-guarantee synthesis as follows: (a) any solution of assume-guarantee synthesis is attack-free; no subset of participants can violate the objectives of the other participants without violating their own objectives; (b) the Asokan-Shoup-Waidner (ASW) certified mail protocol that has known vulnerabilities is not a solution of AGS; and (c) the Kremer-Markowitch (KM) non-repudiation protocol is a solution of AGS. To our knowledge this is the first application of synthesis to fair non-repudiation protocols, and our results show how synthesis can generate correct protocols and automatically discover vulnerabilities. The solution to assume-guarantee synthesis can be computed efficiently as the secure equilibrium solution of three-player graph games. © 2012 Springer-Verlag.","lang":"eng"}],"ec_funded":1,"date_updated":"2025-06-11T08:06:25Z","alternative_title":["LNCS"],"publist_id":"3405","external_id":{"arxiv":["1004.2697"]},"intvolume":"      7148","arxiv":1,"day":"20","acknowledgement":"The research was supported by Austrian Science Fund (FWF) Grant No P 23499-N23 (Modern Graph Algorithmic Techniques in Formal Verification), FWF NFN Grant No S11407-N23 (RiSE), ERC Start grant (279307: Graph Games), and Microsoft faculty fellows award.\r\nThe authors would like to thank Avik Chaudhuri for his invaluable help and feedback.","year":"2012","citation":{"chicago":"Chatterjee, Krishnendu, and Vishwanath Raman. “Synthesizing Protocols for Digital Contract Signing,” 7148:152–68.

We say that the relaxation is totally half-integral if f̂(x) is a polyhedral function with half-integral extreme points x, and this property is preserved after adding an arbitrary combination of constraints of the form x i=x j, x i=1-x j, and x i=γ where γ∈{0,1,1/2} is a constant. A well-known example is the roof duality relaxation for quadratic pseudo-Boolean functions f. We argue that total half-integrality is a natural requirement for generalizations of roof duality to arbitrary pseudo-Boolean functions. Our contributions are as follows. First, we provide a complete characterization of totally half-integral relaxations f̂ by establishing a one-to-one correspondence with bisubmodular functions. Second, we give a new characterization of bisubmodular functions. Finally, we show some relationships between general totally half-integral relaxations and relaxations based on the roof duality. On the conceptual level, our results show that bisubmodular functions provide a natural generalization of the roof duality approach to higher-order terms. This can be viewed as a non-submodular analogue of the fact that submodular functions generalize the s-t minimum cut problem with non-negative weights to higher-order terms."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","intvolume":"       160","external_id":{"arxiv":["1005.2305"],"isi":["000301211100006"]},"issue":"4-5","oa_version":"Preprint","status":"public","_id":"3257","year":"2012","citation":{"ama":"Kolmogorov V.

We used confocally targeted patch-clamp recording from dendrites and axons to map the activation of rat CA3 pyramidal neurons at the subcellular level. Our results reveal two distinct dendritic domains. In the proximal domain, action potentials initiated in the axon backpropagate actively with large amplitude and fast time course. In the distal domain, Na+ channel–mediated dendritic spikes are efficiently initiated by waveforms mimicking synaptic events. CA3 pyramidal neuron dendrites showed a high Na+-to-K+ conductance density ratio, providing ideal conditions for active backpropagation and dendritic spike initiation.

By now it is clear that clues to the understanding of this crucial transition in the evolution of life can arise in a fourth pathway besides the three possibilities in the quest for simplicity outlined by Bonner in his classical book. In other words, solar system exploration seems to be one way in the long-term to elucidate the simplicity of evolutionary development. We place these ideas in the context of different inheritance systems, namely the genotypic and phenotypic replicators with limited or unlimited heredity, and ask which of these can support multicellular development, and to which degree of complexity. However, the quest for evidence on the evolution of biotas from planets around other stars does not seem to be feasible with present technology with direct visualization of living organisms on exoplanets. But this may be attempted on the Galilean moons of Jupiter where there is a possibility of detecting reliable biomarkers in the next decade with the Europa Jupiter System Mission, in view of recent progress by landing micropenetrators on planetary, or satellite surfaces. Mars is a second possibility in the inner Solar System, in spite of the multiple difficulties faced by the fleet of past, present and future missions. We discuss a series of preliminary ideas for elucidating the origin of metazoan analogues with available instrumentation in potential payloads of feasible space missions to the Galilean moons.","lang":"eng"}],"author":[{"full_name":"de Vladar, Harold","id":"2A181218-F248-11E8-B48F-1D18A9856A87","last_name":"de Vladar","orcid":"0000-0002-5985-7653","first_name":"Harold"},{"full_name":"Chela Flores, Julian","last_name":"Chela Flores","first_name":"Julian"}],"title":"Can the evolution of multicellularity be anticipated in the exploration of the solar system?","date_published":"2012-01-01T00:00:00Z","type":"book_chapter","doi":"10.1007/978-94-007-4966-5_22","fulldoi":"https://doi.org/10.1007/978-94-007-4966-5_22"},{"day":"04","publisher":"Springer","citation":{"apa":"Jain, A., Pietrzak, K.

The learning parities with noise problem (LPN) is the special case where the elements of the vectors are bits. In recent years, the LWE and LPN problems have found many applications in cryptography. In this paper we introduce a (seemingly) much stronger adaptive assumption, called &quot;subspace LWE&quot; (SLWE), where the adversary can learn the inner product of the secret and random vectors after they were projected into an adaptively and adversarially chosen subspace. We prove that, surprisingly, the SLWE problem mapping into subspaces of dimension d is almost as hard as LWE using secrets of length d (the other direction is trivial.) This result immediately implies that several existing cryptosystems whose security is based on the hardness of the LWE/LPN problems are provably secure in a much stronger sense than anticipated. As an illustrative example we show that the standard way of using LPN for symmetric CPA secure encryption is even secure against a very powerful class of related key attacks.

In this work we propose a wide variety of other approaches to building efficient MACs, without going through a PRF first. In particular, unlike deterministic PRF-based MACs, where each message has a unique valid tag, we give a number of probabilistic MAC constructions from various other primitives/assumptions. Our main results are summarized as follows: We show several new probabilistic MAC constructions from a variety of general assumptions, including CCA-secure encryption, Hash Proof Systems and key-homomorphic weak PRFs. By instantiating these frameworks under concrete number theoretic assumptions, we get several schemes which are more efficient than just using a state-of-the-art PRF instantiation under the corresponding assumption. For probabilistic MACs, unlike deterministic ones, unforgeability against a chosen message attack (uf-cma ) alone does not imply security if the adversary can additionally make verification queries (uf-cmva ). We give an efficient generic transformation from any uf-cma secure MAC which is &quot;message-hiding&quot; into a uf-cmva secure MAC. This resolves the main open problem of Kiltz et al. from Eurocrypt'11; By using our transformation on their constructions, we get the first efficient MACs from the LPN assumption. While all our new MAC constructions immediately give efficient actively secure, two-round symmetric-key identification schemes, we also show a very simple, three-round actively secure identification protocol from any weak PRF. In particular, the resulting protocol is much more efficient than the trivial approach of building a regular PRF from a weak PRF. © 2012 International Association for Cryptologic Research."}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"fulldoi":"https://doi.org/10.1007/978-3-642-29011-4_22","date_published":"2012-03-10T00:00:00Z","has_accepted_license":"1","ddc":["000","004"],"oa_version":"Submitted Version","_id":"3282","status":"public","publisher":"Springer","acknowledgement":"Supported by the European Research Council under the European Union’s Seventh Framework Programme (FP7/2007-2013) / ERC Starting Grant (259668-PSPC)","year":"2012","citation":{"ama":"Dodis Y, Pietrzak KZ, Kiltz E, Wichs D.

Here, we demonstrate that vaccinia virus (VACV) infection leads to activation of the stress-activated protein kinase (SAPK)/extracellular signal-regulated kinase (ERK) 4/7 (MKK4/7)-c-Jun N-terminal protein kinase 1/2 (JNK1/2) pathway; further, the stimulation of this pathway requires postpenetration, prereplicative events in the viral replication cycle. Although the formation of intracellular mature virus (IMV) was not affected in MKK4/7- or JNK1/2-knockout (KO) cells, we did note an accentuated deregulation of microtubule and actin network organization in infected JNK1/2-KO cells. This was followed by deregulated viral trafficking to the periphery and enhanced enveloped particle release. Furthermore, VACV infection induced alterations in the cell contractility and morphology, and cell migration was reduced in the JNK-KO cells. In addition, phosphorylation of proteins implicated with early cell contractility and cell migration, such as microtubule-associated protein 1B and paxillin, respectively, was not detected in the VACV-infected KO cells. In sum, our findings uncover a regulatory role played by the MKK4/7-JNK1/2 pathway in cytoskeleton reorganization during VACV infection.\r\n","lang":"eng"}],"publist_id":"3356","date_updated":"2025-09-30T07:40:18Z","quality_controlled":"1","article_processing_charge":"No","date_created":"2018-12-11T12:02:29Z","month":"01","page":"172 - 184","publication_status":"published","volume":86,"language":[{"iso":"eng"}],"department":[{"_id":"JoBo"}],"oa":1,"title":"A vaccinia virus-driven interplay between the MKK4/7-JNK1/2 pathway and cytoskeleton reorganization","pmid":1,"type":"journal_article","main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3255887/"}],"doi":"10.1128/JVI.05638-11","publication":"Journal of Virology","author":[{"first_name":"Anna","full_name":"Pereira, Anna","last_name":"Pereira"},{"first_name":"Flávia","full_name":"Leite, Flávia","id":"36705F98-F248-11E8-B48F-1D18A9856A87","last_name":"Leite"},{"last_name":"Brasil","full_name":"Brasil, Bruno","first_name":"Bruno"},{"first_name":"Jamaria","full_name":"Soares Martins, Jamaria","last_name":"Soares Martins"},{"first_name":"Alice","last_name":"Torres","full_name":"Torres, Alice"},{"full_name":"Pimenta, Paulo","last_name":"Pimenta","first_name":"Paulo"},{"last_name":"Souto Padrón","full_name":"Souto Padrón, Thais","first_name":"Thais"},{"first_name":"Paula","last_name":"Tranktman","full_name":"Tranktman, Paula"},{"full_name":"Ferreira, Paulo","last_name":"Ferreira","first_name":"Paulo"},{"last_name":"Kroon","full_name":"Kroon, Erna","first_name":"Erna"},{"full_name":"Bonjardim, Cláudio","last_name":"Bonjardim","first_name":"Cláudio"}],"scopus_import":"1"},{"has_accepted_license":"1","date_published":"2012-08-01T00:00:00Z","ddc":["000"],"fulldoi":"https://doi.org/10.1016/j.patrec.2011.10.007","publist_id":"3330","date_updated":"2025-09-30T07:39:47Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","file_date_updated":"2020-07-14T12:46:06Z","abstract":[{"lang":"eng","text":"The theory of persistent homology opens up the possibility to reason about topological features of a space or a function quantitatively and in combinatorial terms.

The upper level game is a discounted or mean-payoff game and the lower level game is a (undiscounted) reachability game. Two-level games model hierarchical and sequential decision making under uncertainty across different time scales. For both discounted and mean-payoff two-level games, we show the existence of pure memoryless optimal strategies for both players and an ordered field property. We show that if there is only one player (Markov decision processes), then the values can be computed in polynomial time. It follows that whether the value of a player is equal to a given rational constant in two-level discounted or mean-payoff games can be decided in NP ∩ coNP. We also give an alternate strategy improvement algorithm to compute the value. © 2012 World Scientific Publishing Company.","lang":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publist_id":"3326","date_updated":"2025-09-30T07:38:00Z","fulldoi":"https://doi.org/10.1142/S0129054112400308","date_published":"2012-04-01T00:00:00Z","citation":{"chicago":"Chatterjee, Krishnendu, and Ritankar Majumdar. “Discounting and Averaging in Games across Time Scales.” <i>International Journal of Foundations of Computer Science</i>.

Recent functional analysis indicates that in some fast central synapses, transmitter release is triggered by a small number of Ca2+ channels that are coupled to Ca2+ sensors at the nanometre scale. Molecular analysis suggests that this tight coupling is generated by protein–protein interactions involving Ca2+ channels, Ca2+ sensors and various other synaptic proteins. Nanodomain coupling has several functional advantages, as it increases the efficacy, speed and energy efficiency of synaptic transmission.","lang":"eng"}],"file_date_updated":"2020-07-14T12:46:07Z","has_accepted_license":"1","date_published":"2012-01-01T00:00:00Z","ddc":["570"],"fulldoi":"https://doi.org/10.1038/nrn3125"},{"date_created":"2018-12-11T12:02:46Z","project":[{"grant_number":"P 23499-N23","_id":"2584A770-B435-11E9-9278-68D0E5697425","name":"Modern Graph Algorithmic Techniques in Formal Verification","call_identifier":"FWF"},{"grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"call_identifier":"FP7","_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"related_material":{"record":[{"status":"public","id":"5382","relation":"earlier_version"}]},"quality_controlled":"1","page":"270 - 285","publication_status":"published","department":[{"_id":"KrCh"}],"volume":7213,"language":[{"iso":"eng"}],"month":"03","title":"Robustness of structurally equivalent concurrent parity games","oa":1,"type":"conference","doi":"10.1007/978-3-642-28729-9_18","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1107.2009"}],"conference":{"end_date":"2012-04-01","name":"FoSSaCS: Foundations of Software Science and Computation Structures","location":"Tallinn, Estonia","start_date":"2012-03-24"},"corr_author":"1","scopus_import":1,"author":[{"orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu"}],"external_id":{"arxiv":["1107.2009"]},"intvolume":"      7213","_id":"3341","status":"public","oa_version":"Preprint","day":"22","arxiv":1,"publisher":"Springer","year":"2012","citation":{"apa":"Chatterjee, K.

The games are concurrent: in each round, the two players (player 1 and player 2) choose their moves independently and simultaneously; the current state and the two moves determine a probability distribution over the successor states. We also consider the important special case of turn-based stochastic games where players make moves in turns, rather than concurrently. We study concurrent games with \\omega-regular winning conditions specified as parity objectives. The value for player 1 for a parity objective is the maximal probability with which the player can guarantee the satisfaction of the objective against all strategies of the opponent. We study the problem of continuity and robustness of the value function in concurrent and turn-based stochastic parity gameswith respect to imprecision in the transition probabilities. We present quantitative bounds on the difference of the value function (in terms of the imprecision of the transition probabilities) and show the value continuity for structurally equivalent concurrent games (two games are structurally equivalent if the support of the transition function is same and the probabilities differ). We also show robustness of optimal strategies for structurally equivalent turn-based stochastic parity games. Finally we show that the value continuity property breaks without the structurally equivalent assumption (even for Markov chains) and show that our quantitative bound is asymptotically optimal. Hence our results are tight (the assumption is both necessary and sufficient) and optimal (our quantitative bound is asymptotically optimal).","lang":"eng"}],"ec_funded":1}]
