Created in 2002, CryptAlpes is a research group that gathers members from four institutions in Rhône-Alpes (Grenoble and Lyon, France) with common interests and strong cooperations in the field of Cryptography and Security. CryptAlpes addresses mathematical aspects of cryptography (Institut Fourier), optimized implementation of finite field computations (LMC-IMAG) and security aspects of distributed and peer-to-peer computations (ID-IMAG).
