Scientists working for Europe's Telecommunications Standards Institute (ETSI) have devised a new security algorithm, known as A5/3, that will provide network operators and users of GSM mobile phones with an even higher level of protection against eavesdropping than they have already.

The algorithm will be available from the third quarter of this year. It was developed by a joint working party between the GSM Association Security Group and the 3rd Generation Partnership Project (3GPP) for GSM systems, but it will also be useable for the General Packet Radio Service (GPRS) where it will be known as GEA3, and other GSM modes such as High Speed Circuit Switched Data (HSCSD) and enhanced Data Rates for GSM Evolution (EDGE).
