摘要：
We present a fast MPEG video encryption algorithm called RVEA which encrypts selected sign bits of the DCT coefficients and motion vectors using secret key cryptography algorithms such as DES or IDEA. RVEA features bounded computation time for any size of video frame and is robust to both plaintext and ciphertext attack. Since it adds a very small overhead to the MPEG video compression process, a software implementation is fast enough to meet the real-time requirement of MPEG video applications.
