A new security algorithm, called A5/3, has been developed by a joint working group between the GSM Association Security Group and the 3rd Generation Partnership Project (3GPP). It will provide GSM cell phone users with enhanced protection from eavesdropping, and will keep sensitive info, such as phone numbers secure.

A5/3 will be also applicable for the other GSM modes, like GPRS (GEA3) and EDGE.
