Review of Joint Encoding and Encryption for Image Transmission using Chaotic Map, LDPC and AES Encryption

In today’s era of communication, sharing of information is unavoidable. Analysis of security and reliability while communicating is essential. Information may get altered, copied and copyright can be infringed. Previously, digital watermarking and different encryption techniques like AES, DES, HASH and MAC were used as a primary security technique for information hiding. But, in all these methods, there are some vulnerabilities, because of which information may be hacked or changed while transmission. In addition to the security of the information, there should also be an error-free transmission of data. This review paper discusses various image encryption techniques which are using joint error correction and encryption methods. Based on the literature review, a novel method for joint encryption and encoding is suggested. Low-Density Parity-Check (LDPC) code, a highly recommended technique in 5G, is used for reliability. Chaotic sequence based on a logistic map is used for security. Proposed technique also uses the S-Box of AES algorithm for enhancing the security obtained by combining LDPC and Chaotic sequence. This paper aims to provide a general overview of image encryption techniques. Based on the study, a new system for joint encryption and encoding using LDPC, Chaotic map and AES S-Box is suggested.
