WebMar 8, 2016 · In A5/1, there are three shift registers (about 20 bits each), each with a certain bit (about in the middle) controlling clocking.At each cycle, a register is shifted when its clock bit agrees with one or both of the other two clock bits. Under the fair approximation that the clock bits are random, independent, and evenly distributed, a given register is thus … http://koclab.cs.ucsb.edu/teaching/cren/project/2024/jensen+andersen.pdf

WebJun 29, 2024 · The encryption algorithms A5/1 and A5/2 are LFSR-based stream ciphers supporting 64-bit key length. A5/2 is a so-called export cipher designed to offer only 40-bit security level. Usage of export ciphers providing weak security was common at that time and other standards like TLS also supported export cipher suites.
