ABSTRACT:
In a communication system, a password that enables an embedded software program within a base station can be generated using public key cryptography in the following manner. A system controller (103) obtains a unique identification code and an embedded software code for the base station (101). Once obtained, the system controller (103) encrypts the unique identification code and the embedded software code using a private key to produce a password. The password is transferred to the base station (101) where, upon receipt, is decrypted using a public key to produce the unique identification code and the embedded software code. The base station (101) compares the unique identification code and an embedded unique identification code (107) and, when they substantially match, the base station (101) stores the password.
