Secure and Energy-Efficient Key-Agreement Protocol for Multi-Server Architecture
This addresses security and performance issues in multi-server authentication for users and servers, but it is incremental as it builds on earlier schemes.
The authors tackled the problem of inefficient and insecure authentication in multi-server systems by proposing a new protocol that is ~44% more efficient and requires ~38% less communication cost, while enhancing security with two-factor authentication.
Authentication schemes are practised globally to verify the legitimacy of users and servers for the exchange of data in different facilities. Generally, the server verifies a user to provide resources for different purposes. But due to the large network system, the authentication process has become complex and therefore, time-to-time different authentication protocols have been proposed for the multi-server architecture. However, most of the protocols are vulnerable to various security attacks and their performance is not efficient. In this paper, we propose a secure and energy-efficient remote user authentication protocol for multi-server systems. The results show that the proposed protocol is comparatively ~44% more efficient and needs ~38% less communication cost. We also demonstrate that with only two-factor authentication, the proposed protocol is more secure from the earlier related authentication schemes.
