Temporal Key Integrity Protocol and Its Security Issues 431 16.5.2 An Attack Consider that an attacker has obtained two MPDUs such as M 1 and M 2 2 such that The same IVs are used to encrypt both the messages M 1 and M 2 . M 2 is not longer than M 1 . The plaintext P 1 of M 1 is known to the attacker. By knowing the above information, an attacker can calculate K mic . The IVs used to calculate the key stream are same for both the messages M 1 and M 2 . M 1 and the plaintext 1 (P 1 ) are known to the attacker, but the MIC value is unknown to the attacker. The attacker can recover the key stream by using the formula K [i] = M 1 [i] ⊕ P 1 [i] for i = 1, 2, 3, ..., length (M 1 ). By calculating the key stream, we can calculate the MIC value by m = K ⊕ M 1 , where K is the key stream. By finding the MIC value and the plaintext 2, we can calculate the Michael key by applying InvMichael to the MIC value and the message. 16.6 TKIP Countermeasures As we have seen in the previous section, Michael provides a weak protection against active attacks. A successful attack against the Michael MIC means that the attacker could inject unwanted data frames and perform attacks like data modification against the encryption key. TKIP has come up with countermeasures, 1 , if TKIP detects an active attack on the network. The countermeasures are given as follows. When TKIP finds two MIC failures within 60 s, the station and the authenticator which detect the MIC failures must be disabled for a period of 60 s. By doing this, it will become difficult for the attackers to inject a large number of forged data frames in a short period of time. The PTK and the GTK must be changed once the station or the AP detects the MIC failure. To calculate the time, a timer is used to log MIC failures. The supplicant (<strong>wireless</strong> device), when it finds an MIC failure, sends an MIC failure report back to the AP. A Michael MIC failure report is a key frame with the MIC bits, the error bits, the request bit, and the secure bit all set to 1. MLME- MICHAELMIC FAILURE.indication is used to indicate Michael MIC failure to a local supplicant and the authenticator. When the system meets an MIC failure, it relies on the log sheet and a timer to check whether there will be another MIC attack in 60 s seconds. If there is no MIC failure in another 60 s, the process continues; otherwise the AP and the station connected to the authenticator are disconnected for about 60 s. After 60 s, the station gets reassociated to the network and hence carries out the data transfer through the authenticator.
432 Wireless Ad Hoc Networking TKIP countermeasures for the authenticator: When the authenticator receives a frame with a Michael MIC error, it discards the affected frame, increases the Michael MIC failure counter by one, generates the MLME-MICHAELMIC FAILURE.indication primitive, starts the timer, and checks if the Michael MIC failure is reported again. If it is reported again within 60 s, the AP deauthenticates, deletes all PTK for all stations using TKIP, and discards the GTK, and after 60 s, new PTK and GTK are constructed. TKIP countermeasures for the authenticator are shown in Figure 16.12. Wait for michael MIC failure Send a michael MIC failure report Timer
