| 摘 要： | 提出一个有效的基于身份的门限多代理者的代理重加密方案。传统的代理重加密方案中代理者通常都是指独立的个体,而在此处代理者将是一个群体(n个人),只有当其中至少t个人同时参与时,才能进行有效地代理。同时还证明了此方案在标准模型下是selective ID-IND-CCA安全的。

| Abstract: | An efficient ID-based proxy re-encryption scheme with threshold multi-proxy is proposed. Unlike the pre-vious proxy re-encryption schemes, the proxy in this proposal is a group of entities instead of a single entity, only t or more entities out of n entities in the group can realize the functionality of the proxy. Furthermore, this proposal is selective ID-IND-CCA secure in the standard model. |
