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 communication system (101). The technology effectively prevents any human access to the A-Keys and eliminates cloning. The invention improves the security and integrity of the wireless communication system (101). A secure processor (104) exchanges random numbers with a wireless communication device (100) to generate the A-Key. The secure processor (104) then encrypts the A-Key and transfers the encrypted A-Key to an authentication system (103). When the authentication system (103) generates or updates the SSD, the authentication system transfers the encrypted A-Key and other information to the secure processor (104). The secure processor (104) decrypts the A-Key and calculates the SSD. The secure processor (104) transfers the SSD to the authentication system (103) for use in authenticating system (103) the wireless communication device (100).
