Abstract
A method, system, transmitter and receiver for checking an integrity and authenticity of GPRS Tunnelling protocol (GTP) communications of a GPRS system, wherein for each GTP data packed to be sent, the GTP transmitter generates a sequence number indicative of the GTP data packet number, creates the GTP data packet, and computes a digest value associated to the GTP data packet using a shared secret key and information related to the GTP data packet, such as the entire GTP data packet, the IP packet that encapsulates the GTP data packet or NULL data. The GTP transmitter then sends the GTP data packet to a GTP receiver, which uses the shared secret key and the digest value of the GTP data packet to check the authenticity and integrity of the received data packet.
