    摘要： At a transmitter, a program is encrypting according to a one program key, the program key is encrypted, and the encrypted program, the encrypted program key, and non-encrypted PSI data to a receiver are transmitted. At a receiver, the encrypted program, the encrypted program key, and the non-encrypted PSI data are received, the encrypted program key is decrypted, the encrypted program is located according to the non-encrypted PSI data, and the located encrypted program is decrypted according to decrypted program key.

    摘要： Data is encrypted according to a plurality of data keys. During the encryption of the data, the data keys are rotated according to a data key rotation pattern, and the rotation of the data keys includes repetitive use of the data keys during the encryption of the data. The encrypted data is transmitted to a receiver. Additionally or alternatively, encrypted data is received from a transmitter. The encrypted data is decrypted according to a plurality of data keys. During the decryption of the encrypted data, the data keys are rotated according to a data key rotation pattern, and the rotating of the data keys includes repetitive use of the data keys during the decryption of the encrypted data.

    摘要： One embodiment involves encrypting an MPEG transport stream by seeding a random number generator with a seed derived from at least a portion of the MPEG transport stream to produce a random number output. At least one program key and at least one modification key are generated from the random number output. At least portions of the MPEG transport stream are encrypted with the program key. At least one stored key is modified according to the modification key to produce a message segment key. The program key and the modification key are encrypted with the message segment key. The encrypted MPEG transport stream, the encrypted program key, and the encrypted modification key are multiplexed to form a multiplexed output.
