    摘要: A software diversity system including an executable provider to provide an executable program including component blocks such that different combinations of blocks are operative to perform a functionally encryption keys functionally equivalent data transformation, a cipher to encrypt the component blocks with cryptographic keys, a key selector to select a first selection of keys for a first device, such that the first selection is operative to decrypt a first combination of the blocks operative when executed to perform the same functionally equivalent data transformation, and select a second selection of keys for a second device, such that the second selection is operative to decrypt a second combination of the blocks operative when executed to perform the same functionally equivalent data transformation, and a transfer module to prepare for transfer the first and second selection of cryptographic keys for transfer to the first and second device, respectively. Related apparatus and methods are also included.

    摘要: A method and system for associating metadata with an encrypted content item, the method including receiving metadata for association with a content item, receiving an entitlement control packet (ECP) associated with the content item, applying a cryptographic hash function to the ECP, thereby generating an ECP hash value, combining the ECP hash value with the metadata, thereby creating a data control object, performing a cryptographic operation on the data control object, thereby generating cryptographic integrity data, and joining the cryptographic integrity data to the data control object after the cryptographic operation, wherein usage of the content by the recipient is dependent on both a validation of the ECP hash value and a validation of the cryptographic integrity data. Related apparatus and methods are also described.
