- A novel image cryptosystem by using projection pursuit based blind source separation is proposed in this work, where the plaintexts need to be neither independent nor sub-independent. In the proposed cryptosystem, for encryption, the plaintexts are mixed linearly with each other first, and then mixed nonlinearly with the ciphers. As for decryption, a projection pursuit based blind source separation method is employed. The processes of both encryption and decryption are fast, thus it is suitable for large scale of images. In addition, the ciphers can be used repeatedly. Simulations are given to illustrate the availability and the security of our cryptosystem.
