- •
A compressionencryption system of image based on SPIHT and Chirikov map is proposed.
- •
Encryption scheme is designed to operate with SPIHT without degrade its performance.
- •
Our work is supported on many mathematical tools and chaotic systems.
- •
The proposal scheme can resist against exhaustive key and cryptanalytic attacks.
- •
A high speed and very secure system with very low computational complexity.
