WebJul 1, 2024 · A5/1 Cipher Algorithm - Its uses and its history. A5/1 is a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard. It is one of several implementations of the A5 security protocol. It was initially kept secret, but became public knowledge through leaks and reverse engineering. 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".

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.
