ABSTRACT

Ubiquitous Sensor Network(USN), the core technology for the Ubiquitous environments, must be operated in the restrictive battery capacity and computing. From this cause, USN needs the lightweight design for low electric energy and the minimum computing. The previous mutual authentication, based on 's trust model, in USN has a character that makes the lightweight mutual authentication possible in conformity with minimum computing. But, it has an imperfection at the components of representing the trust from a lightweight point of view. In this paper, we improve on the 's trust model to apply a lightweight mutual authentication in USN. The proposed trust model in USN defines the trust information with the only degree of trust-entity()'s belief. The defined trust information has a superiority over the 's trust model from a computing point of view, because it computes information by probability and logic operation(AND).
