Abstract

A method for managing data of devices using one or more computing entities includes encrypting, by one or more encrypting entities, the data based on encryption policies using encryption keys; storing the encrypted data as ciphertext at a storing entity; requesting decryption keys to decrypt the stored ciphertext by one or more clients; computing restricted decryption keys based on access right policies for the requesting clients by a security management entity; and providing the generated decryption keys to the requesting clients for decrypting the stored ciphertext.
