Although ZK-PoK have a high potential impact, their real world deployment is  typically hindered by their significant complexity compared to other (non-interactive) crypto primitives. Moreover, their design and implementation are time-consuming and error-prone.\n\nWe contribute to overcoming these challenges as follows: We present a comprehensive specification language and a compiler for ZK-PoK protocols based on Σ-protocols. The compiler allows the fully automatic translation of an abstract description of a proof goal into an executable implementation. Moreover, the compiler overcomes various restrictions of previous approaches, e.g., it supports the important class of exponentiation homomorphisms with hidden-order co-domain,  needed for privacy-preserving applications such as DAA. Finally, our compiler is certifying, in the sense that it automatically produces a formal proof of the soundness of the compiled protocol for a large class of protocols using the Isabelle/HOL theorem prover. \n"}],"author":[{"first_name":"José","full_name":"Almeida, José Bacelar","last_name":"Almeida"},{"first_name":"Endre","full_name":"Bangerter, Endre","last_name":"Bangerter"},{"full_name":"Barbosa, Manuel","last_name":"Barbosa","first_name":"Manuel"},{"orcid":"0000-0003-2835-9093","id":"329FCCF0-F248-11E8-B48F-1D18A9856A87","last_name":"Krenn","full_name":"Stephan Krenn","first_name":"Stephan"},{"full_name":"Sadeghi, Ahmad-Reza","last_name":"Sadeghi","first_name":"Ahmad"},{"full_name":"Schneider, Thomas","last_name":"Schneider","first_name":"Thomas"}],"publist_id":"3724","citation":{"chicago":"Almeida, José, Endre Bangerter, Manuel Barbosa, Stephan Krenn, Ahmad Sadeghi, and Thomas Schneider. “A Certifying Compiler for Zero-Knowledge Proofs of Knowledge Based on Sigma-Protocols.” edited by Dimitris Gritzalis, Bart Preneel, and Marianthi Theoharidou, 6345:151–67.
