The GSM Association last week announced a new security algorithm, known as A5/3, to provide users of GSM mobile phones with improved protection against eavesdropping. A5/3 has been developed by a joint working party between the GSM Association Security Group and the 3rd Generation Partnership Project (3GPP). It will also be useable for the General Packet Radio Service (GPRS) where it will be known as GEA3, and other GSM modes, including EDGE. The A5/3 encryption algorithm also supplies signalling protection, so that sensitive information such as telephone numbers are protected.
