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"}],"publication_status":"published","quality_controlled":0,"alternative_title":["LNCS"],"title":"A Certifying Compiler for Zero-Knowledge Proofs of Knowledge Based on Sigma-Protocols","main_file_link":[{"open_access":"1","url":"http://eprint.iacr.org/2010/339.pdf"}],"_id":"2979","doi":"10.1007/978-3-642-15497-3","conference":{"name":"ESORICS: European Symposium on Research in Computer Security"},"author":[{"last_name":"Almeida","first_name":"José","full_name":"Almeida, José Bacelar"},{"first_name":"Endre","full_name":"Bangerter, Endre","last_name":"Bangerter"},{"first_name":"Manuel","full_name":"Barbosa, Manuel","last_name":"Barbosa"},{"last_name":"Krenn","id":"329FCCF0-F248-11E8-B48F-1D18A9856A87","full_name":"Stephan Krenn","first_name":"Stephan","orcid":"0000-0003-2835-9093"},{"last_name":"Sadeghi","first_name":"Ahmad","full_name":"Sadeghi, Ahmad-Reza"},{"last_name":"Schneider","first_name":"Thomas","full_name":"Schneider, Thomas"}],"intvolume":"      6345","extern":1,"type":"conference","date_updated":"2021-01-12T07:40:13Z","publist_id":"3724","volume":6345}
