Inventors: John Baras, Paul Yu, Brian Sadler
Researchers at the University of Maryland, in cooperation with the Army Research Laboratory, have developed a method of efficiently updating and exchanging secret keys that exploits the randomness of Markov models in selecting a new key. This new method eliminates the need for third-party key management or public key infrastructure, explicit communication of keys between sender and receiver, and large amounts of storage space. The system has perfect forward secrecy and is resistant to known key attack methods and interception by third parties. A patent application is pending.
