What is... Isogeny-Based Cryptography?

Vortrag von Silvia Sconza

Datum: 21.11.23  Zeit: 16.30 - 17.30  Raum:

''In cryptography, we are always looking for hard mathematical problems on which to build secure protocols for exchanging messages. Current cryptography is based on the difficulty of integer factorisation and the Discrete Logarithm Problem. Unfortunately, both of these problems can be solved on (sufficiently powerful) quantum computers in an acceptable time thanks to Shor's algorithm (1994). Hence the need to look for new problems that are also hard on quantum computers. A good proposal in this direction is the Isogeny Path Problem, which gave rise to Isogeny-Based Cryptography. We will take a friendly look at the problem and the cryptosystems based on it.''
