There has been a considerable debate on the applicability of conventional encryption techniques for protecting images. Chaos based encryption systems are preferred for digital image encryption for a long time now. For a reliable encryption method any alteration in image content or the key must be reflected in the cipher image. The present work demonstrates a highly secure and reliable encryption of...
A data encryption model based on logistic map is studied and multiple chaotic dynamical systems were implemented to improve by addressing the issues related to use of logistic map. Use of different chaotic systems other than logistic map, provides us to vary control parameters to a larger extent, hence enabling to overcome the limitations of logistic map without compromising security of data. Further,...
Reed-Solomon code or RS code is widely used for error corrections of data in transmission and storages. However, it is thought of as insecure for direct implementation in code-based cryptography due to plaintext-known attacks. In recent years, McEliece cryptosystem with enhanced public key security by generalized RS code and Goppa code are discussed for hardware implementation. In this work, from...
In this paper, we introduce novel techniques to improve the performance of representative Authentication Encryption (AE) functions namely Galois/Counter Mode of operation (GCM) on modern high-end IoT platforms (ARM–NEON), which support SIMD and cryptography instruction set. The GCM requires efficient counter mode of encryption and binary field multiplication. The 128-bit binary field multiplication...
