Application of cryptosystems in protection of data content

This paper asks the question of how to apply cryptosystems to protect data content transmitted via network. Protection means retaining privacy and integrity, availability of information and user identification. Data content security enables a large number of applications (such as e-commerce, e-mail, resource access control in distributed systems, digital signing of films, and so on) realizable in network computer systems, contributing thereby to popularization and spreading of computer networks. Methods and techniques of cryptographic protection are shown, also the advantages and disadvantages of symmetric and asymmetric cryptosystems in particular fields of application. Data authentication is described, and the stress is laid on a digital signature and some its specific forms such as blind signature and signature of potentially infinite streams. At the end, there is given description of modes of entity authentication (also called identification) by use of passwords and challenge-response protocols.
