27.11.3.4.2 Procedure
a) The ME is made to initiate a VERIFY CHV command. b) The SIM simulator answers the first 3 bytes with ACK=INS complemented. c) The SIM simulator answers the next data byte with NULL (NULL="60"). d) The SIM simulator then sends ACK=INS. This byte is sent when the elapsed time since step b) is greater than the work waiting time. e) The SIM simulator answers the transmission of the rest of the data with NULL. f) The SIM simulator then sends SW1 and SW2, indicating correct execution of the command ("90" and "00" for SW1 and SW2 respectively). These bytes are sent when the elapsed time since step d) is greater than the work waiting time.

27.12.1.1 Definition
Authentication is performed by a GSM network on the SIM, by sending a random number to the SIM. The SIM then performs a calculation on the random number, and sends the result to the network for verification.

27.12.1.4.2 Procedure
An authentication is made in the same way as in test [26.7.2. Authentication]. The MS is paged. After the MS has responded with a PAGING RESPONSE message to the SS, the SS initiates an authentication procedure, sending the MS the value RAND. During authentication, the SIM simulator checks the frequency of the clock supplied by the ME. Following the AUTHENTICATION RESPONSE from the MS, the SS sends CHANNEL RELEASE.
