* Plugin to provide a USIM card/provider using the 3GPP2 (S.S0055) standard.
*
* This plugin implements the standard of the 3GPP2 (S.S0055) and not the one
* of 3GGP, completely in software using the libgmp library..
* The shared key used for authentication is from ipsec.secrets. The
* peers ID is used to query it.
* The AKA mechanism uses sequence numbers to detect replay attacks. The
* peer stores the sequence number normally in a USIM and accepts
* incremental sequence numbers (incremental for lifetime of the USIM). To
* prevent a complex sequence number management, this implementation uses
* a sequence number derived from time. It is initialized to the startup
* time of the daemon.
* To enable time based SEQs, define SEQ_CHECK as 1. Default is to accept
* any SEQ numbers. This allows an attacker to do replay attacks. But since
* the server has proven his identity via IKE, such an attack is only
* possible between server and AAA (if any).
