Noncommutative cryptography is based on applications of algebraic structures like noncommutative groups, semigroups and non-commutative rings. Its inter-section with Multivariate cryptography contains...
CPA-to-CCA Transformation for KDM Security
public-key encryption key-dependent message security chosen ciphertext security
2019/6/3
We show that chosen plaintext attacks (CPA) security is equivalent to chosen ciphertext attacks (CCA) security for key-dependent message (KDM) security. Concretely, we show how to construct a public-k...
Security of the Fiat-Shamir Transformation in the Quantum Random-Oracle Model
Fiat-Shamir post-quantum digital signatures
2019/3/1
The famous Fiat-Shamir transformation turns any public-coin three-round interactive proof, i.e., any so-called sigma-protocol, into a non-interactive proof in the random-oracle model. We study this tr...
