Security research of L2TPv3 protocol
Abstract:In this paper the principle of L2TPv2 protocol is introduced, and then its security drawback is discussed. To improve the performance of security, L2TPv3 is brought forward. We analyze the control message and data message of L2TPv3 for security improvement, which includes aperiodic certification, data encryption and integrality examination. Further the procedure of establishing safe VPDN connection using L2TPv3 is set forth.
