Abstract
A method of validating communications between a transmitting component and a receiving component of a paging system is disclosed. The transmitting component prepares an application protocol data unit (APDU) for transmission by selecting predetermined portions of the APDU for hashing. A hash code is output by the hash method and included in the APDU. The receiving component retrieves the same predetermined portions of the APDU for hashing. The receiving component then compares the hash code in the APDU with the hash code the receiving component calculated. If there is a match, then the APDU is accepted as authentic. If there is not a match, then the APDU is rejected.
