WebJun 20, 2024 · Hashing to Groups. Many cryptographic protocols rely on the hardness of solving the Discrete Logarithm Problem (DLP) in special groups, one of which is the integers reduced modulo a large integer. To guarantee that the DLP is hard to solve, the modulus must be a large prime number. Increasing its size boosts on security, but also makes ... WebCryptography Research.

Group-based cryptography is a use of groups to construct cryptographic primitives. A group is a very general algebraic object and most cryptographic schemes use groups in some way. In particular Diffie–Hellman key exchange uses finite cyclic groups. So the term group-based cryptography refers mostly to cryptographic protocols that use infinite nonabelian groups such as a braid group.
WebJan 25, 2024 · Cryptographic group actions are a relaxation of standard cryptographic groups that have less structure. This lack of structure allows them to be plausibly quantum resistant despite Shor’s algorithm, while still having a number of applications.
