摘要: A secure digital content delivery system includes a content provider and a content user. The content provider delivers encrypted content to the content user in response to delivery requests. The content provider generates encryption algorithms on the fly and encrypts the content prior to delivery, using a different encryption algorithm and key for each content delivery. The content user subsequently requests access permission from the content provider, to access the encrypted content. The content provider grants access by generating an executable decryption module on the fly and providing the executable decryption module to the content user. The content user decrypts the content and accesses it on the fly, using the executable decryption module. The accessed content is then re-encrypted using a different encryption algorithm and key, to preserve the integrity of the secure content delivery system. The content delivery system uses a programmably configurable protocol parsing engine to encrypt and decrypt content.

摘要: Embodiments of the invention provide a general-purpose data modification system and methods of use. A common system is used for modifying any data composed of interrelated data structures similar to the protocols found in network frames. A common logic control module is configured to perform any number of data modification operations, based on programmably configurable protocol descriptions defining the data modification operations.

摘要: A secure digital content delivery system includes a content provider and a content user. The content provider delivers encrypted content to the content user in response to delivery requests. The content provider generates encryption algorithms on the fly and encrypts the content prior to delivery, optionally using a different encryption algorithm and key for each content delivery. The content user subsequently requests access permission from the content provider, to access the encrypted content. The content provider grants access by generating an executable decryption module on the fly and providing the executable decryption module to the content user. The content user decrypts the content and accesses it on the fly, using the executable decryption module. The accessed content is then re-encrypted using a different encryption algorithm and key, to preserve the integrity of the secure content delivery system. The content delivery system uses a programmably configurable protocol parsing engine to encrypt and decrypt content. The content delivery system is able to generate executable code to implement the functions of the protocol parsing engine, to streamline the processing of the content.
