Mutual authentication method for ubiquitous service environments
Minoru Matsumoto, Yasushi Takagi · 2004
This paper proposes a mutual authentication method to achieve high scalability using a simple mechanism. Communication records with a corresponding node are used as a seed to generate the secret key, so mutual authentication is executed using this generated secret key. This will reduce the number of authentication keys required for mutual authentication and processing loads per user in the entire communication network. We show the validity of this proposed method by applying an assumed ubiquitous network model.
