IEEE 802.15.3 High Rate WPAN is a mechanism for wireless home network such as PDAs, digital video camcoder, etc. While symmetric keys are used for MAC layer security, the process of establishing a secure membership or a secure relationship is outside of the scope of the standard. In addition, to prepare for ubiquitous environment in the near future, it is important to study the process of establishing a secure relationship between DEVs in different dependent piconets. This paper propose a secure model and a process of establishing a secure relationship using PKI without a ousted certificate authority.
