Forgery Attack Sample Clauses

Forgery Attack. Assume that an intruder wants to impersonate Xxxxx to establish the common session keys with Xxx. The intruder forges the previously intercepted message (rA1, rA2, rA3, sA, Cert(yA)) to (r’A1, r’A2, r’A3, s’A, Cert(yA)) and send it to Xxx, where (r’A1, r’A2, r’A3 and s’A) k’A = k’A1 + k’A2 + k’A3 mod q and n2 keys can be used. In our protocol, two parties can establish (n2 + n) common secret session keys and all the keys can be used. It is seen that our protocol is superior to other protocols. Note that n denotes that two parties send n Xxxxxx-Xxxxxxx public keys. In Table 2, we show an example to compare the efficiency of our scheme to the others.

Forgery Attack. In this attack, an eavesdropper intercepts the message that a user A broadcasts through the public channel. The eavesdropper uses the intercepted message to assume the identity of A and masquerade as A to other users. By a reasoning similar to that for Key Offset Attack, it is clear that the protocol of Farash and Attari has a vulnerability to this kind of attack and the extra terms being sent in our protocol remedies this vulnerability. In addition to these attacks, as demonstrated in [MM13], the protocol in [FAA14] is vulnerable to Known Session Specific Temporary Information Attack (KSTIA) and Key Compromise Impersonation Attack (KCI). λ
