多组件属性的远程证明

Multi-component property based remote attestation

在现有组件属性证明方案的基础上,提出了多组件属性的证明方案,以解决多个组件以一定的结构构成的安全属性的证明问题,满足不同类型属性的证明需求。以CL签名为基础进行多个组件与属性的签名,使组件-属性的映射具有多对一的关系,并对各组件的组成结构进行了简要分析。多组件属性的证明方案具有组件验证效率高,协议配置灵活,可兼容单组件的属性证明等特点,证明平台的隐私可以得到保证。多组件属性证明方案适用于具有特定组件结构的属性证明。

On the basis of component property-based attestation,multi-component property based attestation(MCPBA)is proposed to solve the attestation problem with the security property consists of some components in a special structure.This scheme can satisfy the attestation requirements of different kind of properties.A several-for-one mapping between components and property is established based on blocks of messages signature in Camenisch and Lysyanskaya signature scheme.MCPBA has an efficient component property attestation method,which is suitable for both multi and single component-property.The component property based attestation that proved secure in RO model under strong RSA assumption is the secure base of MCPBA,to make certain of privacy protection.MCPBA is suitable for the property attestation that has a special components structure.
