  • APPARATUS AND ASSOCIATED METHODOLOGY FOR MANAGING CONTENT CONTROL KEYS
    Publication number: 20120063597
    Abstract: A method of exchanging secret session keys in symmetric encryption communication includes storing random number tables in both the sending and receiving devices. The sending device then determines the secret session key utilizing the random number table, and transmits to the receiving device information for locating the secret session key within the random number table. Thus, the sending device shares the secret session key with the receiving device without actually transmitting the secret session key. The random number tables may be transmitted from one device to the other or be preinstalled in each device. Further, a common seed value may be used by each device to generate the random number table independently.
