We show a general connection between various types of statistical zero-knowledge (SZK) proof systems and (unconditionally secure) secret sharing schemes. Viewed through the SZK le...

We introduce a novel concept of dual-system simulation-sound non-interactive zero-knowledge (NIZK) proofs. Dual-system NIZK proof system can be seen as a two-tier proof system. As...

Quasi-adaptive non-interactive zero-knowledge (QA-NIZK) proofs is a recent paradigm, suggested by Jutla and Roy (Asiacrypt ’13), which is motivated by the Groth-Sahai seminal tec...

In 2012, NIST standardized SHA-512/224 and SHA-512/256, two truncated variants of SHA-512, in FIPS 180-4. These two hash functions are faster than SHA-224 and SHA-256 on 64-bit pla...
