To ensure the confidentiality and integrity of data, it is necessary to use encryption techniques; the safety of these techniques is based on the pro- tection of keys and algorithms used by those techniques. Indeed, the estab- lishment of an encryption key management system (creation, storage, distribu- tion, etc...) is paramount. However, the safety of this type of system in the context of Cloud Computing is based on the protection of the data dictionary (metadata). The protection of this dictionary is a real challenge in a no-trust context. This paper describes the implementation of a protection technique for the Cryptographic Key Management System’s metadata, which provides handling (Consulting / Editing) data without offending the confidentiality and integrity of the dictionary.
