Alekseychuk А. М. On the computational security of randomized stream ciphers proposed by Mihaljević and Imai [Електронний ресурс] / А. М. Alekseychuk, S. V. Gryshakov // Захист інформації. - 2014. - Т. 16, № 4. - С. 328-334. - Режим доступу: http://nbuv.gov.ua/UJRN/Zi_2014_16_4_12 This paper yields a (computational) security analysis for a generic class of randomized stream ciphers based on joint employment of encryption, error-correction coding, and dedicated random coding. We show that the security of these ciphers can be considerably less than their designers claim. In contrast to the approach for security evaluation used before, our technique is significantly simpler and allows us to find out the code-theoretic sense of parameters that determine the security of these ciphers. We also propose another possible solution (based on nonlinear random coding) for design of randomized stream ciphers with enhanced security.
