Article: A survey on security and efficiency issues in chaotic image encryption Journal: International Journal of Information and Computer Security (IJICS) 2016 Vol.8 No.4 pp.347 - 381 Abstract: The advent of digital and telecommunication technology, especially the internet, has paved the way for diversifying multimedia applications. Multimedia data such as video, audio and images have manifested themselves in proliferating internet-based applications. Consequently, there is a rapid growth of chaos-based cryptographic techniques to ensure security functionalities like confidentiality, integrity, or authentication. A host of research work based on chaotic cryptosystem has been proposed to satisfy the specific requirements defined for image communication. Despite all the notable development surrounding the chaotic cryptosystem, many of the proposed methods negotiate with the required number of attributes that influences the design of the cryptosystems. Associated with this issue, careful scrutinisation of the performance of the existing chaos-based encryption techniques is needed for its further development towards practical applications. A new taxonomy of image encryption techniques according to their association with the chaotic system employed in three different categories has been propounded to assess the security and efficiency functionalities. This survey attempts to summarise the existing image encryption techniques in all the three categories followed by a discussion on the security and efficiency constraints.

Abstract: The advent of digital and telecommunication technology, especially the internet, has paved the way for diversifying multimedia applications. Multimedia data such as video, audio and images have manifested themselves in proliferating internet-based applications. Consequently, there is a rapid growth of chaos-based cryptographic techniques to ensure security functionalities like confidentiality, integrity, or authentication. A host of research work based on chaotic cryptosystem has been proposed to satisfy the specific requirements defined for image communication. Despite all the notable development surrounding the chaotic cryptosystem, many of the proposed methods negotiate with the required number of attributes that influences the design of the cryptosystems. Associated with this issue, careful scrutinisation of the performance of the existing chaos-based encryption techniques is needed for its further development towards practical applications. A new taxonomy of image encryption techniques according to their association with the chaotic system employed in three different categories has been propounded to assess the security and efficiency functionalities. This survey attempts to summarise the existing image encryption techniques in all the three categories followed by a discussion on the security and efficiency constraints.
