- 2 abstract "A5/2 is a stream cipher used to provide voice privacy in the GSM cellular telephone protocol. It was used for export instead of the relatively stronger (but still weak) A5/1. It is one of seven A5 ciphering algorithms which have been defined for GSM use. The cipher is based on a combination of four linear feedback shift registers with irregular clocking and a non-linear combiner.In 1999, Ian Goldberg and David A. Wagner cryptanalyzed A5/2 in the same month it was published, and showed that it was extremely weak – so much so that low end equipment can probably break it in real time.Since July 1, 2006, the GSMA (GSM Association) mandated that GSM Mobile Phones will not support the A5/2 Cipher any longer, due to its weakness, and the fact that A5/1 is deemed mandatory by the 3GPP association. In July 2007, the 3GPP has approved a change request to prohibit the implementation of A5/2 in any new mobile phones. If the network does not support A5/1, or any other A5 algorithm implemented by the phone, then an unencrypted connection can be used.".
