“…On the basis of the previous works [13,37], we proposed to combine the three encryption methods together, taking into account all the already mentioned improvements to preserve the CR. The compression process as well as all the interventions of our encryption algorithm in our scheme are explained below.…”

“…We obtain the binary sequence by comparing each value generated to 1/2. For all the previous works [13,19,24,37], using one binary sequence generated from a logistic chaotic map [32] as a dynamic key for all of the selected coefficients without renewal, threatens the security of our algorithm. That is why, we thought of making the sequence renewable to avoid using some binary parts from the generated sequence repetitively.…”

“…Indeed, the encryption algorithm can affect the prediction module. This method is discussed in [10][11][12][13] where the intra-prediction modes are the encrypted information. Hiding the prediction mode is beneficial to prevent the decoding part from reconstructing the real video.…”

“…As studied above, researchers opted to combine many different parameters for the encryption, in order to scramble the decoded video content as much as possible. For this reason, we conceive our encryption scheme by combining three different parameters previously studied one by one which are non-zero quantified coefficients on CAVLC entropy coding [24], signs of MVs [19] and optional intra-prediction modes [13]. Previously, we have already studied the combination of both non-zero quantified coefficients on CAVLC entropy coding and signs of MVs [37].…”

“…Many video encryption algorithms are proposed according to the different semantic elements of encryption. Some schemes are 2 of 15 proposed in those articles [4,5] to encrypt the video by scrambling the intra prediction mode (IPM) of the intra-coded macro block. Exclusive OR (XOR) operation is usually used in intra prediction mode (IPM) to protect data privacy.…”

The protection of video data has become a hot topic of research. Researchers have proposed a series of coding algorithms to ensure the safe and efficient transmission of video information. We propose an encryption scheme that can protect video information with higher security by combining the video coding algorithm with encryption algorithm. The H.264/AVC encoding algorithm encodes the video into multiple slices, and the slices are independent of each other. With this feature, we encrypt each slice while using the cipher feedback (CFB) mode of the advanced encryption standard (AES) with the dynamic key. The key is generated by the pseudo-random number generator (PRNG) and updated in real time. The encryption scheme goes through three phases: constructing plaintext, encrypting plaintext, and replacing the original bitstream. In our scheme, we encrypt the code stream after encoding, so it does not affect the coding efficiency. The purpose of the CFB mode while using the AES encryption algorithm is to maintain the exact same bit rate and produce a format compatible bitstream. This paper proposes a new four-dimensional (4-D) hyperchaotic algorithm to protect data privacy in order to further improve the security of video encryption. Symmetric encryption requires that the same key is used for encryption and decoding. In this paper, the symmetry method is used to protect the privacy of video data due to the large amount of video encrypted data. In the experiment, we evaluated the proposed algorithm while using different reference video sequences containing motion, texture, and objects.
