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. 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.

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.
