文摘
- •
A new nonlinear image encryption–decryption system in the Gyrator domain is proposed.
- •
High quality of the decrypted image and an enhanced level of security are achieved.
- •
Gyrator transform and fully phase coding add resistance against intruder attacks.
- •
The proposed scheme is suitable for optoelectronics and/or digital implementation.
