The conference was originally planned to take place in Yokohama, Japan, but had to change to an online format due to the COVID-19 pandemic. The 40 papers included in these proceedings were carefully reviewed and selected from 137 submissions. They focus on all aspects of public-key cryptography, covering cryptanalysis; MPC and secret sharing; cryptographic protocols; tools; SNARKs and NIZKs; key exchange; theory; encryption; and signatures.Security and Cryptology,2946-1863 ;13178CryptographyData encryption (Computer science)Computer networksCoding theoryInformation theoryComputer networksSecurity measuresApplication softwareCryptologyComputer Communication NetworksCoding and Information TheoryMobile and Network SecurityComputer and Information Systems ApplicationsCryptography.Data encryption (Computer science)Computer networks.Coding theory.Information theory.Computer networksSecurity measures.Application software.Cryptology.Computer Communication Networks.Coding and Information Theory.Mobile and Network Security.Computer and Information Systems Applications.005.824005.824Watanabe YoheiHanaoka GoichiroShikata JunjiMiAaPQMiAaPQMiAaPQBOOK9910548172603321Public-key cryptography - PKC 20222920090UNINA
