Agree-and-Prove: Generalized Proofs Of Knowledge and Applications
PoK Knowledge and Applications
2019/6/5
Proofs of knowledge (PoK) are one of the most fundamental notions in cryptography and have been used as a building block in numerous applications. The appeal of this notion is that it is parameterized...
Non-malleable encryption with proofs of plaintext knowledge and applications to voting
anonymity applications election schemes
2019/1/16
Non-malleable asymmetric encryption schemes which prove plaintext knowledge are sufficient for secrecy in some domains. For example, ballot secrecy in voting. In these domains, some applications deriv...
Improved Non-Interactive Zero Knowledge with Applications to Post-Quantum Signatures
zero-knowledge proofs signatures
2018/5/28
Recent work, including ZKBoo, ZKB++, and Ligero, has developed efficient non-interactive zero-knowledge proofs of knowledge (NIZKPoKs) for arbitrary Boolean circuits based on symmetric- key primitives...
The notion of \emph{zero-knowledge} \cite{GMR85} is formalized by requiring that for every malicious efficient verifier $V^*$, there exists an efficient simulator $S$ that can reconstruct the view of ...
Efficient and Non-Malleable Proofs of Plaintext Knowledge and Applications
Efficient and Non-Malleable Proofs Plaintext Knowledge Applications
2009/4/13
We describe very efficient protocols for non-malleable (interactive) proofs of plaintext
knowledge for the RSA, Rabin, Paillier, and El-Gamal encryption schemes whose
security can be proven in the s...
