Abstract
A method, computer-readable storage device and apparatus for encrypting a broadcast message of a base station are disclosed. For example, the method selects an encryption key for the broadcast message and encrypts the broadcast message using the encryption key to create an encrypted broadcast message. The method then transmits an identifier of the encryption key and transmits the encrypted broadcast message over a broadcast channel. A method for decrypting a broadcast message that is encrypted is also disclosed.
