摘要/Abstract

摘要： 在基于密文策略属性加密方案中,中央授权中心(CA)作为参与生成用户属性私钥的重要机构,对其安全性要求较高.传统方案中,单个CA被攻击,系统的安全性便无法保证.为了解决该问题,文章采用多授权中心.方案中各个CA同时计算用户的解密密钥;由各个属性授权中心(AA)管理相应的属性集合,并根据属性集合进行属性权重分割,实现属性加权.通过理论分析,该方案在保证系统安全性的同时,更具有实际意义.

关键词: 属性加密, 属性权重, 多授权中心

Abstract: In the attribute encryption scheme based on the ciphertext policy,the central authorization center(CA),as an important organization involved in generating the private key of the user attribute,thus, the central anthorization center is required for the high security.In the traditional scheme, if the single CA is attacked, the security of the system can not be guaranteed.In order to solve this problem, the paper adopts the multi-authorization center.In this scheme, each CA calculates the decryption key of the user at the same time.The attribute authority(AA)manages the corresponding attribute set and divides the attribute weight according to the attribute set to realize weight attributes.By the theoretical analysis, the scheme not only ensures the security of the scheme,but also makes it more practical.

Key words: attribute encryption, attribute weight, multi-anthorization center
