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.

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.
