Recent Federal Communications Commission rules promise a whole new set of possible applications, which allow unlicensed use on a secondary basis of the Television White Spaces (TVWS), called as cognitive radio technology. ECMA-International launched the first step towards realizing these applications by creating and adopting industry standards. This paper reviews the first industrial standards for personal/portable devices in the TVWS from ECMA-International focused on the security aspects. After that, we point out the lack of security facilities in the standard, which does support the link-to-link security but not for the end-to-end security, and then propose two location-based authentication protocols to cope up with the deficiencies over cognitive radio networks. We use location information as thesecurecredentialfor the authentications. The protocols can be support privacy issues of consumer premise equipments and integrated into the extensible authentication protocol.
