عنوان انگلیسی A New Image Encryption Algorithm Using a Hyperchaotic Lorenz System to Produce Efficient and Sufficiently Swift Responses to Different Security Needs of Clients
چکیده انگلیسی مقاله Abstract:
This paper proposes a new plaintext-related mechanism based on plaintext encryption. For simplicity, PCODE was proposed as the image encryption code. The original picture was encoded to get the proposed encryption and plaintext encryption with a chaotic sequence to control the PCODE rules. Another chaotic sequence was encoded into a PCODE sequence for the PCODE XOR operation. The remaining two chaotic sequences were then processed with the proposed scheme to get two key streams for the permutation phase. The cipher image was obtained after the conventional permutation and PCODE XOR operations. The use of the proposed plaintext encryption leads to the correlation between the keystreams used in the displacement phase and both the secret key and the plaintext image. This correlation increases the sensitivity and security of the encryption system with respect to the plaintext. The experimental findings from simulation show that the proposed encryption system shows significant efficiency and security.
