Development of a Novel Hyperchaos-Based Image Encryption Algorithm Consisting of Two Scrambling-Diffusion Operations

Table 7

Encryption times and information entropies of the encrypted images.

Encryption algorithms	Images (size)	Times (s)	Information entropies
Proposed one with two scrambling-diffusion operations	Baboon (256 × 256)	0.559	7.999
An existing algorithm with one scrambling-diffusion operation	Baboon (256 × 256)	0.484	7.997
