Effective software-oriented cryptosystem in complex PC security software

Authors: A. Moldovyan, N. Moldovyan, P. Moldovyan

Abstract

To ensure high encryption rate and good data security, an organization of an encipherement program in the form of two modules was proposed. The first module is used for customizing the second one, the latter being the resident of the program, which maintains all application calls about encryption procedures. This approach is shown to be perspective for the elaboration of the cryptosystems with indefinite cryptalgorithm. Several typical software-oriented cryptoschemes are considered. The developed cryptomodules have high encipherement rate (2-10 Mbps for Intel 386) and secure high information protection level Organization of a new computer security software complex COBRA is considered. High enciphering rate and good data protection are provided by the resident cryptomodule using less than 1 kbyte of the main memory and working in dynamic encryption mode.
