The most important tools to argue about pseudoentropy are chain rules, which quantify by how much (in terms of quantity and quality) the pseudoentropy of a given random variable X decreases when conditioned on some other variable Z (think for example of X as a secret key and Z as information leaked by a side-channel). In this paper we give a very simple and modular proof of the chain rule for HILL pseudoentropy, improving best known parameters. Our version allows for increasing the acceptable length of leakage in applications up to a constant factor compared to the best previous bounds. As a contribution of independent interest, we provide a comprehensive study of all known versions of the chain rule, comparing their worst-case strength and limitations."}],"file":[{"date_updated":"2020-07-14T12:45:11Z","creator":"system","access_level":"open_access","checksum":"8cd4215b83efba720e8cf27c23ff4781","file_name":"IST-2016-669-v1+1_599.pdf","content_type":"application/pdf","relation":"main_file","file_size":443340,"file_id":"5351","date_created":"2018-12-12T10:18:29Z"}],"date_published":"2015-08-15T00:00:00Z","oa_version":"Submitted Version","project":[{"name":"Provable Security for Physical Cryptography","_id":"258C570E-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"259668"}],"year":"2015","volume":9230,"pubrep_id":"669","ddc":["005"],"page":"81 - 98","doi":"10.1007/978-3-319-22174-8_5","department":[{"_id":"KrPi"}],"publication_status":"published","alternative_title":["LNCS"],"month":"08","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"The chain rule for HILL pseudoentropy, revisited","oa":1,"date_created":"2018-12-11T11:53:22Z","_id":"1669","file_date_updated":"2020-07-14T12:45:11Z","author":[{"id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak","first_name":"Krzysztof Z"},{"full_name":"Skórski, Maciej","last_name":"Skórski","first_name":"Maciej"}],"intvolume":"      9230","quality_controlled":"1"}
