A lightweight dynamic pseudonym identity based authentication and key agreement protocol without verification tables for multi-server architecture

作者：

Highlights：

• We give the security analysis and figure out some crucial security flaws of Li et al.ʼs protocol (Li et al., 2012 [25]).

• Based on Li et al.ʼs protocol, we propose an improved protocol which is fit for the multi-server architecture.

• By using protected pseudonym identities, our proposed protocol provides user anonymity. Meanwhile, it provides traceability.
