    Abstract: Since cloud storage becomes a major application in cloud computing, many
    researches have been focusing on how to protect and verify the data stored in the Cloud.
    There is a problem that the owner doesn’t want the real data stored by the Cloud to
    be Cloud known. Therefore, the most popular way is to encrypt entire file by using
    a secret key like Amazon Simple Storage Service (S3) [1]; however it may bring some
    problems such as secret key change and distribution, key management, and access rights
    management. So, we propose a hierarchical key management scheme to solve the problems
    mentioned above. And this scheme is suitable for individuals or enterprise service
    providers to manage their keys of files, software, and services.
