SECURE PROCESSING FOR AUTHENTICATION OF A WIRELESS COMMUNICATIONS DEVICE

摘要

The invention provides technology that improves the security of the A-Keys in a wireless communications system. The technology effectively prevents any human access to the A-Keys and eliminates cloning. The invention improves the security and integrity of the wireless communications system. A secure processor exchanges random numbers with a wireless communications device to generate the A-Key. The secure processor then encrypts the A-Key and transfers the encrypted A-Key to an authentication system. When the authentication system generates or updates the SSD, the authentication system transfers the encrypted A-Key and other information to the secure processor. The secure processor decrypts the A-Key and calculates the SSD. The secure processor transfers the SSD to the authentication system for use in authenticating the wireless communications device.
