| Summary: | The provable security of ID-based key exchange protocols was investigated. In the universally composable framework, the provable secure model of ID-based key exchange was proposed. The ability of the adversary to corrupt key generation center was added to the adversary model. According to the characteristics of ID-based key exchange, the ideal functionality of ID-based key exchange was presented. Based on the adversary model and the ideal functionality, the proposed model captures not only the universally composable security of ID-based key exchange, but also implies one of the important properties of ID-based key exchange——key generation center forward secrecy. In addition, the protocol （with key confirmation） proposed by Chen and Kudla can securely realize the functionality of ID-based KE with KGC-FS. |
