A5 has two variations: The ”stronger“ A5/1 and the ”weaker“ A5/2 which are fully described in section 3.3. Both variations have a common way of encrypting data by encoding plaintext/decoding cyphertext with an XOR operation with pseudo random bits.

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 … WebTable 1.
