Summary: Cryptanalysis plays a crucial role in the design of image cryptographic systems. In this study, a two-round image cryptographic system was analyzed and found to have vulnerabilities that allowed successful decryption of encrypted images through chosen-plaintext attacks. The encryption scheme was improved to enhance security, and the improved system demonstrated better resilience against chosen-plaintext attacks while maintaining the same encryption performance as the original scheme.

Summary: In this paper, a universal two-dimensional (2D) enhanced cosine coupled model (2D-ECCM) is designed for constructing new chaotic systems. Two new maps, 2D Logistic-sine coupled map (2D-NLSCM) and 2D cubic-tent coupled map (2D-NCTCM), generated using 2D-ECCM, show better chaotic behaviors compared to existing 2D chaos. An image adaptive encryption algorithm utilizing 2D-NLSCM is proposed, incorporating adaptive scrambling and bidirectional-sequential diffusion methods for pixel manipulation. The algorithm proves its superior encryption efficiency and resistance against common cryptanalytic attacks with an average information entropy of 7.9988 and average chi-square of 238.3495.
