Anonymity. Assume that an adversary overhears on wireless packet and spoofs the identities, e,g., XXXXx and connects to the NAN gateway, it does not send SMIDj as a plaintext but hide the identity in Q1 = ESTj [SMIDj , NID, T 1]. Moreover, it can be noticed from the proposed scheme that the pseudonymity of idSTj is being provided using α and β. Resultant, only the legitimate NAN gateway can learn the identity of meter by decrypting Q1 = ESTj [SMIDj , NID, T 1] using the secret token (STj). Thus, it achieves identity anonymity and protects from identity spoofing attack. In addition, the comparison on security services among [14], [17], [19]–[23] and the proposed scheme is given in Table II. We can notice that the proposed LAKA can provide more security services than previously proposed ones.
