Algebraic Techniques for Short(er) Exact Lattice-Based Zero-Knowledge Proofs
Lattices Zero-Knowledge Proofs Commitments
2019/6/4
A key component of many lattice-based protocols is a zero-knowledge proof of knowledge of a vector s⃗ s→ with small coefficients satisfying As⃗ =u⃗ modqAs→=u→modq. While there exist ...
Algebraic Techniques in Differential Cryptanalysis
Algebraic Techniques Differential Cryptanalysis
2009/6/4
In this paper we propose a new cryptanalytic method against
block ciphers, which combines both algebraic and statistical techniques.
More specifically, we show how to use algebraic relations arising...
