| Abstract: | Since the security of traditional stream ciphers is very much influenced by more and more attacks, the secure cryptosystems of new types are desired. This paper develops the stream ciphers with information feedback of which the simplest types were studied earlier. The security of these new cryptosystems are analysed and their value for practice is pointed out. The primary analysis shows that the stream ciphers with information feedback are of high security. |
