Abstract
A survey of some important scientific directions in the sphere of symmetric cryptography is presented. We emphasize problems connected with weak keys, with statistical analysis of symmetric algorithms and with investigation of iterative constructions. Some problems, specific to stream ciphers, iterative block ciphers and cryptographic hash-functions are considered. We also advocate practical significance of scientific work in cryptanalysis and sketch its basic principles.
