Abstract—The roaming service enables mobile subscribers to access the Internet service anytime and anywhere, which can fulfill the requirement of ubiquitous access for the emerging paradigm of networking, e.g., the Internet of Things (IoT).

CPAL provides an anonymous user linking function by utilizing a novel group signature technique, which can not only efficiently hide users ’ identities, but also enable the authorized entities to link all the access information of the same user without knowing the user’s real identity. Specifically, by using the master linking key possessed by the trust linking server, the authorized foreign network operators or service providers can link the access information from the user to improve its service, while
