| Popis: | 94 We propose an off-line roaming authentication protocol which not only the server in a foreign network authenticates any roaming user without the involvement of the home network, but also the anonymity of the user is preserved. That is, the user can prove his/her roaming legality without letting the server know his/her real identity. We employ the ID-based signature technique and secret sharing technique to provide the user anonymity and non-repudiation of roaming service during the mutual authentication process. The proposed scheme only requires two messages exchanged between the roaming user and the server, and a polynomial function is designed to revoke the roaming service of an illegal user. |
