Security Enhancement Algorithm Based on Memristive Chaos and Its Application in the Internet of Things

With the vigorous development of the industrial Internet of Things, the information security problem under the information interaction mode of the Internet of Things has gradually become a hot topic. The existing security enhancement technology has some problems, such as lack of security and practicability, difficulty in materialization and so on. In view of this situation, an encryption algorithm based on memristor hyperchaos system is proposed and implemented on the platform of Internet of Things. Firstly, the original image information is processed, and the original image matrix is stored as a binary matrix. Secondly, the chaotic sequence is generated by using the determined parameters, and some values are selected to assume the key function. Thirdly, the key is normalized, and the high randomness of the sequence generated by the hyperchaotic system is used for encryption operations such as mask and diffusion. Finally, the generated ciphertext is sent to the receiving end. Experimental results and analysis show that the algorithm has the advantages of large key space and strong sensitivity to plaintext and key. Its successful implementation on the Internet of things platform shows that this algorithm is expected to be applied in the industrial Internet of Things.
