Abrégé
(EN)

An advanced encryption and key exchange (AEKE) algorithm for quantum safe cryptography is disclosed. The AEKE algorithm does not use hard mathematical problems that are easily solvable on a quantum computer with Shor's algorithm. Instead, new encryption algorithm uses simple linear algebra, rank deficient matrix and bilinear equation, which will be easy to understand, fast, efficient and practical but virtually impossible to crack.
