摘要: 卫星网络具有信道开放、节点暴露、星上处理能力受限等独有特征,但现有的基于密文策略的属性加密(CP-ABE)的访问控制不支持策略完全隐藏且属性授权方式不适用于卫星网络,为此,提出支持策略隐藏的多授权访问控制方案。该方案采用更灵活的线性秘密共享(LSSS)矩阵访问结构,不仅能有效保证数据机密性,而且能通过混淆访问结构实现策略完全隐藏;采用多授权机构实现细粒度的属性管控,能消除中心授权机构的性能瓶颈;各属性授权机构独立工作且密钥生成分权,能有效抵抗合谋攻击。安全性及性能分析表明,所提方案满足数据机密性、抗合谋攻击和完全策略隐藏的安全需求,比对比方案更适合卫星网络。

Abstract: Satellite network has unique characteristics that differ from traditional networks, such as channel openness, node exposure and limited onboard processing capability. However, existing Ciphertext-Policy Attribute-Based Encryption (CP-ABE) access control is not suitable for the satellite network due to its policy explosion and attribute-based authorization manner. To address this problem, a multi-authority access control scheme with policy hiding of satellite network was proposed. Linear Secret Sharing Scheme (LSSS) matrix access structure was adopted to guarantee data confidentiality and hide the access control policy completely by obfuscating the access structure. In addition, multi-authority was used to achieve fine-grained attribute management, eliminating the performance bottleneck of central authority. Each attribute authority worked independently and generated partial key of the user, which makes it resistant to collusion attacks. The security and performance analysis show that the proposed scheme can satisfy the security requirements of data confidentiality, collusion attack resistance and complete policy hiding, and is more suitable for satellite network than the comparison solutions.
