Abstract
Secrecy of a software stream cipher based on p-ary Generalized Self-Shrinking Generator (pGSSG) is examined in this paper. Background information for the generator’s algorithm is provided. The software architecture and key management for the cipher initialization are explained. Galois Field GF(257 32 ) and feedback polynomials are chosen for initialization of the generator. In order to examine the secrecy mathematical model of the software system is made. It is proved that the cipher is not perfect but the empirical tests result in less than 0,0125% deviation of the encrypted files’ entropy from the perfect secrecy. At last the proposed cipher is compared to four eSTREAM finalists by key length and period.
