Hash key-based video encryption scheme for H.264/AVC

  title={Hash key-based video encryption scheme for H.264/AVC},
  author={Xiaofeng Wang and Nanning Zheng and Lihua Tian},
  journal={Sig. Proc.: Image Comm.},
An improved H.264/AVC comprehensive video encryption scheme is proposed. In the proposed scheme, the intra-prediction mode, motion vector difference, and quantization coefficients are encrypted. A novel hierarchical key generation method is likewise proposed, in which the encryption keys are generated based on the cryptographic hash function. Generated frame keys are consistent with the corresponding frame serial numbers, which can ensure frame synchronization in the decrypting process when… CONTINUE READING
