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. WebA5/1 is a synchronous stream cipher based on linear feedback shift registers (LFSRs). It has a 64 -bit secret key. A GSM conversation is transmitted as a sequence of 228-bit … 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. dyna-glo btu natural gas/propane wall heater
