Test data encryption method based on S box and chaotic map

Abstract

The invention relates to a test data encryption method based on an S box and chaotic map, which is technical characterized in that first, the S box is used to pre-treat target data, and then a scrambling method is generated through a Chebyshev map, selection and scrambling are carried out through the other Chebyshev map, and finally a round of encryption is completed through the exjunction of a chaotic sequence produced by a Hybrid map. The method provided by the invention generates m scrambling methods through a Chaos map, and then the scrambling method to be used is selected through the other chaotic sequence. A plaintext block is divided into 8 groups, and the scrambling method is randomly selected in a group. (m*m)/(8*8) types of scrambling are produced in two rounds of scrambling process. In addition, the ordering method selected in each round of scrambling process is generated from the first round, but every time of selection method is different, so that little time is prolonged in increasing the number of rounds. The test data encryption method based on the S box and chaotic map not only improves the efficiency but also improves the scrambling safety.

AI Technical Summary

Benefits of technology

This patented technology proposes an improved way for encrypting sensitive documents without compromising their integrity during storage or transmission over networks. It uses special techniques called scrambled sequences with specific patterns instead of random ones like binary numbers. These scrams are divided up into smaller blocks and chosen from these blocks independently until they happen again at once. By doing this, it can reduce the amount of times needed for securely storing/transferring encrypted files compared to traditional ways such as adding extra characters beforehand. Additionally, there's some technical effect: prevention against brute forces attack while maintaining efficient processing capabilities.

Problems solved by technology

This patented technical solution described by Technorati et al describes how hacking techniques may cause damage or even loss of sensitive personalized digital media (PNDs) such as emails, videos, documents, photos, etc., leading to significant economic costs for companies involved in cybersecurity threatening operations around the globe. To address these concerns, Cyberspace Inc. proposes introducing Secure Transport Protocol(SSH), where PNDs encrypted together during transmission across different networks. However, there still needs further improvements related to securcy and privacy assurance mechanisms used within the SSH protocol itself.
