Summary:PROBLEM TO BE SOLVED: To provide a technology that improves security and integrity of a wireless communications system by effectively preventing any unauthorized access to an authentication key (A-Key) and eliminating cloning in a wireless communication system. SOLUTION: 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 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 the authenticating system 103 and the wireless communication device 100. COPYRIGHT: (C)2011,JPO&INPIT
