Towards Sound Fresh Re-Keying with Hard (Physical) Learning Problems.

2016 · IACR Cryptology ePrint Archive

Most leakage-resilient cryptographic constructions aim at limiting the information adversaries can obtain about secret keys. In the case of asymmetric algorithms, this is usually obtained by secret sharing aka masking the key, which is made …
Chipmunk: Better Synchronized Multi-Signatures from Lattices

2023

Multi-signatures allow for compressing many signatures for the same message that were generated under independent keys into one small aggregated signature. This primitive is particularly useful for proof-of-stake blockchains, like Ethereum, where the same block …
