"Webwhereas the very similar algorithm A8 generates the session key for the A5 encryption cipher. 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. " - Cipher's a5

WebA5/2 is the intentionally weaker version of A5/1 which has been developed — due to the export restrictions — for deploying GSM outside of Europe. Though the internals of both ciphers were kept secret, their designs were disclosed in 1999 by means of reverse engineering [BGW99]. In this work we focus on the stronger GSM cipher A5/1.
