DGBES: Dynamic Group Based Efficient and Secure Authentication and Key Agreement Protocol for MTC in LTE/LTE-A Networks

摘要

The machine to machine communication (MTC) has grown into one of the fastest expansion in the area of Information and Communication Technology and is one of the important aspect of the Internet of Things. It allows millions of devices to connect with each other over the internet. MTC has a huge market and massive strength to obtain numerous application scenarios. The applications of MTC are reliable and effective only after a successful authentication of MTC devices. Hence, there are several group based authentication and key agreement (AKA) protocols were proposed by researchers. Whenever a number of MTC devices simultaneously generate the access request to the LTE/LTE-A network, each MTC device needs a separate authentication process to access the core network that leads to genuine signaling congestion problem. In addition, the existing group based AKA protocols did not equip with the group management scheme efficiently and also vulnerable to various known attacks. To avoid the aforesaid problems and mitigate the authentication complexity of the earlier schemes, we propose a dynamic group based efficient and secure (DGBES-AKA) protocol for MTC in LTE/LTEA network. The proposed protocol consists the group key update scheme with key forward and backward secrecy. The formal verification using ProVerif and security analysis of the proposed protocol represent the security against malicious attacks. Finally, we show the qualitative and quantitative analysis of the DGBES-AKA protocol with the existing protocols. The analysis shows that the proposed protocol has improved results in terms of communication and computation overhead.
