Multiple-image encryption based on chaotic phase mask and equal modulus decomposition in quaternion gyrator domain

作者：

Highlights：

• A novel cryptosystem for multiple color images in quaternion domain is developed.

• The equal modulus decomposition is performed on quaternion spectrum indirectly.

• The chaotic mask that is related to color plaintext images achieves high security.

• The real-valued ciphertext image makes the storage and transmission convenient.
