TL;DR: The proposed algorithm can decrypt the plaintext image with little loss of information, but the content of the original image is visible, and the number of pixel change rate (NPCR) and unified average change intensity (UACI) for the proposed encryption scheme is higher than 99.4% and 33, respectively.

TL;DR: A practical chosen-plaintext attack is performed which reveals that the cryptosystem depending on only multiplication and bitwise XOR operation can be effortlessly attacked.

TL;DR: In this article, the authors reported security flaws in the recently offered encryption technique based on a chaotic map for Internet of Health Things (IoHT) security and proposed some improvements to enhance the security of the understudy cryptographic algorithm.

TL;DR: In this paper, an efficient methodology of creating highly non-linear cryptographic substitution boxes as an alternate to chaotic, or algebraic construction methods is introduced. But, the construction of the S-boxes is performed using particle swarm optimization (PSO).

TL;DR: In this paper, an image encryption technique by using isomorphic elliptic curves which are proved to be effective against side-channel attacks and have efficient key size as compared to other public-key structures was proposed.
