Annotatsiya
This article analyzes the vulnerabilities of the A5/1 stream cipher algorithm and proposes two new approaches to attack it. The first method is based on reconstructing the values of registers by analyzing the dependencies of majority bits, while the second method focuses on reverse-calculating the initial values of registers. Research results indicate that the A5/1 algorithm has weaknesses that can be exploited to recover the initial state of registers or predict the key stream in advance. This article aims to explore the possibilities for in-depth cryptanalysis of the A5/1 algorithm, develop new attack methods, and assess the algorithm's security level.
