Secure signature in GPRS tunnelling protocol (GTP)

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