The present invention provides a method and an apparatus for providing encryption of information exchanged over a network link (200) during a mobile-to-mobile call between a near end member and a far end member. A transcoder (300) servicing the near end member decrypts information from a network element (370) servicing the near end member with a first session key, and encrypts the information with a second session key. The transcoder (300) transmits the information encrypted with the second session key through the network link (200) to a network element servicing the far end member. |
