Title:
Universally Composable Secure Group Communication
Authors: Youliang Tian, Changgen Peng
Abstract:This paper analyzes group communication within the universally composable framework. We first propose the group communication model, identity-based signcrytion model and group key distribution model in the UC framework by designing the ideal functionality \mathcal {F}_{SAGCOM}, \mathcal {F}_{IDSC} and \mathcal {F}_{GKD}, respectively. Then, we construct a UC secure identity-based signcryption protocol \pi_{IDSC}. Moreover, we shows that the identity-based signcryption \pi_{IDSC} securely realizes the ideal functionality \mathcal {F}_{IDSC} if and only if the corresponding protocol IDSC is secure. Finally, based on the identity-based protocol, we propose a group communication scheme \pi_{SAGCOM}, which can securely realizes the ideal functionality \mathcal {F}_{SAGCOM} in the (\mathcal {F}_{IDSC},\mathcal {F}_{GKD})-hybrid model.
