In ubiquitous computing, many computers serve each person at any time and any place. These computers could be thin servers and only have low computation and communication capacity. In this paper, we propose a novel user authentication and key agreement scheme suitable for ubiquitous computing environments. The main merits include: (1) there are many security domains which have their own security controllers, and each security domain can be formed dynamically; (2) a user only has to register in a security controller once, and can use all permitted services in this environment; (3) a user can freely choose his own password to protect his secret token; (4) the computation and communication cost is very low; (5) servers and users can authenticate each other; (6) it generates a session key agreed by the server and the user; (7) our proposed scheme is a nonce-based scheme which does not have a serious time-synchronization problem.
