可应用于分布式系统的多授权中心基于属性的签名

在多授权中心基于属性的加密方案的基础上，提出了可应用于分布式系统的多授权中心基于属性的签名方案。与传统的单授权中心方案相比，本方案允许多个授权中心相互独立地管理属性且分配对应的属性私钥，用户中心只管理用户而不需要监督各用户属性的授权，即由各属性授权中心负责验证用户是否合法授予指定的属性，每一个属性只能被一个属性授权中心管理。本方案具有高效的签名流程，在签名的整个流程中只需要很少量的配对，而且具有良好的灵活性，在实际应用中具有较大的实用价值。...

Summary:在多授权中心基于属性的加密方案的基础上，提出了可应用于分布式系统的多授权中心基于属性的签名方案。与传统的单授权中心方案相比，本方案允许多个授权中心相互独立地管理属性且分配对应的属性私钥，用户中心只管理用户而不需要监督各用户属性的授权，即由各属性授权中心负责验证用户是否合法授予指定的属性，每一个属性只能被一个属性授权中心管理。本方案具有高效的签名流程，在签名的整个流程中只需要很少量的配对，而且具有良好的灵活性，在实际应用中具有较大的实用价值。
Bibliography:Abstract ： This paper proposed a multi-authority attributed based signature scheme based on distributed ABE, which was suit- able for distributed system. It compared with traditional schemes, our scheme allowed an arbitrary number of authorities to in- dependently maintain attributes and distribute secret attribute keys. The master authority was responsible for the distribution of secret user keys, without need to supervise each attribute authority. Attribute authorities were responsible to verify whether a user is eligible of a specific attribute, and every attribute is associated with a single attribute authority. Our construction was very efficient, as it required only a small amount of pairing operations during sign and verification. Our scheme has a good flexibility, and has a great of practical value in practical applications.
