| 英文摘要 | There are tremendously large amount of files in the cloud, and if we encrypt them one by one, there must be the same amount of keys we should manage safely. One important key management approach is centralized key management, which employs a centralized key server to update and assign the data encryption key to the legitimate users via rekey messages. However, users may have different access rights to multiple data streams, forming a partially ordered hierarchy for users. Hence, we need hierarchicalaccess control schemes for the partially ordered user hierarchy. This paper analyses two well-knownhierarchical access control algorithms and points out the security weakness. We show that their schemes are susceptible to attacks such as the ex-member attack and the collusion attack. We propose a modification to their algorithm. |
