WebWith A5/1 we use three shift registers with feedback (Figure 1). With a stream cipher, we often generate an infinitely long key stream which is then EX-OR'ed with the data stream. … 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.

Made during first year of engineering school. How the A5/1 stream cipher works. (from Wikipedia) An implementation of the A5/1 Stream Cipher made by Malgorn Maxime and Poulain Pierre. It's a school project, so you can find bugs and interpretation errors.
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. http://koclab.cs.ucsb.edu/teaching/cren/project/2024/jensen+andersen.pdf

A5/2 is a stream cipher used to provide voice privacy in the GSM cellular telephone protocol. It was designed in 1992-1993 (finished March 1993) as a replacement for the relatively stronger (but still weak) A5/1, to allow the GSM standard to be exported to countries "with restrictions on the import of products with cryptographic security features".
