碩士 === 國立中興大學 === 資訊科學系所 === 95 === There are many important problems in ubiquitous computing environment. One of them is how to associate between wireless devices spontaneously to achieve secure communication. These associations can be roughly divided into two types: short-term associations and long term associations. The TAP (touch-mediated association protocol) belongs to the latter. This thesis focuses on TAP scheme and one of its devices, Mediator. One problem of the Mediator is that it can not authenticate the devices belong to legal owners which request to associate with Mediator. This will effectuate the secure information compromised. In this thesis, we propose a scheme which takes advantage of the time of flight and the secret sharing to solve this problem.
