ABSTRACT:
A selectively encrypted data unit includes an encrypted version of sensitive information (capable of being decrypted to reveal the sensitive information), a plurality of auxiliary values, and an attribute vector associated with the encrypted version of the sensitive information. The selectively encrypted data unit and a unique capability key are accessed. The unique capability key is associated with a key descriptor and is responsive to one or more cryptosystem parameters, one or more random numbers and one or more shares of a master secret. Next the technology determines whether the attribute vector is filtered or enabled by the key descriptor. If so, a protection key is acquired that is responsive to the one or more cryptosystem parameters, the plurality of auxiliary values, the key descriptor and the unique capability key. Once acquired, the protection key is used to decrypt the encrypted version to generate the sensitive information which is presented.
