What do you mean by "message center" ? Do you mean MSC (mobile service
switching centre)? Encryption/decryption in GSM is done in between MS
(mobile station) and BS (base station). Keys are stored in SIM and AuC
(authentication center).

Anyway, can you point some vendors that provide hardware that supports A5/3 ?
