Abstract: An improved key encryption system is provided for encrypting sensitive data on a shared data store. Various embodiments contemplate a system where a plurality of data clients are connected to one or more shared data stores. A secure data storage facility is provided on one or more of the shared data stores by using an encryption scheme. Encryption keys for decrypting the sensitive data are stored on the same data store as sensitive data, which may be decrypted using the encryption keys. To provide another layer of security, the data encryption keys are themselves encrypted using a key encryption key (“KEK”), which is generated by, and stored in a local data store associated with the data clients.
