Abstract: Due to the inefficiency of the existing identity authentication protocol during the login and password update phase in the existing wireless medical sensor network environment, an elliptic curve cryptosystem based authentication protocol suing smart card was presented. The proposed protocol can quickly detect incorrect inputs. The proposed protocol combines the Hash function with the elliptic curve encryption algorithm, which makes its login and password update phases more efficient. Finally, using the BAN logic analysis, it is given that the proposed scheme is more secure than other protocols. The proposed protocol's computing performance and communication costs is also superior to other related authentication protocols.
