zero knowledge Post-Quantum digital signatures Multivariate cryptography
2019/5/21
We then remove the helper from the protocol with a "cut-and-choose" protocol and we apply the Fiat-Shamir transform to obtain signature schemes with security proof in the QROM. We show that the result...

Post-quantum cryptography multivariate cryptography 55-pass identification schemes
2017/7/19
We propose SOFIA, the first MQ-based signature scheme provably secure in the quantum-accessible random oracle model (QROM). Our construction relies on an extended version of Unruh's transform for 5-pa...
It is well known that multivariate quadratic (MQ) digital signature schemes have small signatures but huge public keys. However, in some settings, such as public key infrastructure (PKI), both variabl...
