摘要	To keep the data in the cloud confidential against unauthorized parties, a cryptographic access control solution called hybrid cloud re-encryption (HCRE) based on attribute-based encryption (ABE) was introduced. HCRE designed a secret sharing scheme to delegate the task of ABE re-encryption to the cloud service provider (CSP), which alleviates the administering burdens on the data owner. Experiments show that HCRE can handle dynamic access policies in a more efficient way. Additionally, HCRE does not reveal extra information of the plaintext to the CSP, thus it does no harm to the data confidentiality.
其他摘要	针对云存储中敏感数据的机密性保护问题,在基于属性的加密基础上提出了一种密文访问控制方法HCRE。其思想是设计一种基于秘密共享方案的算法,将访问控制策略变更导致的重加密过程转移到云端执行,从而降低权限管理的复杂度,实现高效的动态密文访问控制。实验分析表明HCRE显著降低了权限管理的时间代价,而且没有向云端泄露额外的信息,保持了数据机密性。
