Abstract: A method for encryption wide-bandwidth video, using a first processor for encrypting the video and a second processor for decrypting the video. Data is taken in blocks. A block of data is scrambled to generate scrambled data, then partitioned into a first portion and a second portion. A global key is generated at the first processor and the second processor, using public key technology. At the first processor, the global key is exclusively-ORed with the first portion, thereby generating a encrypted second portion. At the first processor, a random number is generated from the first portion and exclusively-ORed with the second portion to generate an encrypted second portion. At the second processor, the global key is exclusively-ORed with the encrypted first portion. At the second processor, the random number is recovered from the decrypted first portion and exclusively-ORed with the encrypted second portion to decrypt it. The scrambled data are descrambled, thereby recovering the data.
