METHOD AND APPARATUS FOR SECURE TRANSMISSION OF DATA

摘要

An apparatus and method are utilized for transmitting data across an interface
between a sender and a receiver. The sender and receiver can be provided with
a shared key, a receiver_key and a sender_key. A payload message can be
combined with the keys to generate a unique message for transmission across
the interface. The payload message can be authenticated utilizing the same
input and the same algorithm on the receiving end of the transmission. The
resulting confirmatory payload message can be utilized with the authenticating
payload message to authenticate the payload message.
