One of major applications in cloud computing is cloud storage service. It’s an important research issue to protect the stored data from illegal access by the system manager in the Cloud. To encrypt entire file by using data owner’s secret keys is the simple solution. However it will raise a key management problem. To solve this problem, Hwang and Sun proposed a hierarchical key management scheme. In their scheme, the data owner could change the encryption key more easily, and not to affect…

Analysis of One Scheme for Enabling Cloud Storage Auditing with Verifiable Outsourcing of Key Updates

TLDR
It is remarked that Yu et al.'s scheme for cloud storage auditing with verifiable outsourcing of key updates has two inherent weaknesses: 1) it does not truly mitigate the client's computational burden for key updates; 2) itdoes not ensure confidentiality since the files uploaded to the cloud by the client are eventually not encrypted at all.
