MiMC and GMiMC are families of MPC-friendly block ciphers and hash functions. In this note, we show that the block ciphers MiMC-2n/n2n/n (or Feistel-MiMC) and univariate GMiMC are vulnerable to an att...
Algebraic Cryptanalysis of STARK-Friendly Designs: Application to MARVELlous and MiMC
MARVELlous Jarvis Friday
2019/4/25
The block cipher Jarvis and the hash function Friday, both members of the MARVELlous family of cryptographic primitives, were recently proposed as custom designs aimed at addressing bottlenecks involv...
MiMC: Efficient Encryption and Cryptographic Hashing with Minimal Multiplicative Complexity
distributed cryptography cryptanalysis block ciphers
2016/5/23
We explore cryptographic primitives with low multiplicative complexity. This is motivated by recent progress in practical applications of secure multi-party computation (MPC), fully homomorphic encryp...
