The paper presents the formal security analysis of 3GPP standardized OpenID with Generic Bootstrapping Architecture protocol which allows phone users to use OpenID services based on SIM credentials. We have used an automatic protocol analyzer to prove key security properties of the protocol. Additionally, we have analyzed robustness of the protocol under several network attacks and different threat models (e.g., compromised OP, user entity). The result shows the protocol is secure against key security properties under specific security settings and trust assumptions.
