User anonymity is very important security technique in distributed computing environments that an illegal entity cannot determine any information concerning the user%26apos;s identity. In 2006, Kumar Rajendra proposed a Secure Identification and Key agreement protocol with user Anonymity (SIKA). This paper demonstrates the vulnerability of the SIKA protocol and then presents an improvement to repair the security flaws of the SIKA protocol.
