QUASICRYSTAL MODELS IN CRYPTOGRAPHY

QUASICRYSTAL MODELS IN CRYPTOGRAPHY M. Nesterenko and J. Patera Theoretical properties of quasicrystals are used to propose a symmetric encryption method of digital 2D data. The advantages of the cipher are strict aperiodicity and everywhere discontinuous property as well as the speed of computation, simplicity of implementation and a straightforward possibility of extending the method to encryption of higher dimensional data.
