Security analysis Mobile device stolen attack Untraceability attack Session key is fully protected in the proposed protocol Achieves the session key verification property Mutual authentication property is ensured in the proposed protocol Anonymity of the medical professional The gateway node impersonation attack is fully protected in the proposed protocol

Performance(1/2)

Performance(2/2)

Conclusion A robust and anonymous user mutual authentication protocol is designed to monitor patient health using wireless medical sensor networks. The proposed protocol has superior performance than the existing protocols.
