“…Adaptation of encrypted content has been made possible in [4,[11][12][13], but these techniques adversely affect the compression efficiency of the entropy coder. Technique proposed by Wu and Kuo [8] maintains the compression efficiency, but the existence of invalid Huffman codewords in encrypted bitstream makes it infeasible to perform content adaptation without decryption.…”

Augmentation in communication and coding technology has made encryption an integral part of secure multimedia communication systems. Security solution for end-to-end image transmission requires content adaptation at intermediate nodes, which consumes significant resources to decrypt, process, and reencrypt the secured data. To save the computational resources, this paper proposes a network-friendly encryption technique, which can be implemented in transparency to content adaptation techniques. The proposed encryption technique maintains the compression efficiency of underlying entropy coder, and enables the processing of encrypted data. Thorough analysis of the technique, as regards various standard evaluation parameters and attack scenarios, demonstrates its ability to withstand known-plaintext, ciphertext-only, and approximation attacks. This justifies its implementation for secure image transmission for end-to-end communication systems.

A method to protect video contents from unauthorized access is known as a video encryption scheme. This paper first surveys the literature to identify most desired features of an encryption algorithm. Then a classification has been drawn according to their characteristics. After that, some of the algorithms are discussed and their working has been explained briefly. At the end a comparison has been shown displaying their performance on a few chosen parameters.

“…Four linear transformation are defined to encrypt the video pixels . It can keep the compression efficiency of the video codec [27]. But Li et all (2007) shows that the scheme is not secure enough against brute force attacks because its key space is not sufficiently large.…”

Encryption is the widely used technique to offer security for video communication and considerable numbers of video encryption algorithms have been proposed. The paper explores the literature for already proposed video encryption algorithms with the focus on the working principle of already proposed video encryption schemes. This study is aimed to give readers a quick overview about various video encryption algorithms proposed so far. General TermsEncryption, video security, video encryption metric, compression, decompression.
