Abstract
The concept Web of Things (WoT) goes well beyond the emphasis on the Internet as a means of sharing data, instead of introducing all resources and connections involving computers, data, and people to the Web. It, therefore, focuses on a range of problems and opportunities, thus paving the way for several exciting industries applications. In cryptography a range of main characteristics of chaotic systems such as non-linearity, initial condition sensitivity, and mixing properties are available. These characteristics provide an essential connection between cryptography and chaos. GOST block cipher is based on secret key secrecy. However, when the encryption process with the same key is used for plaintext, the same cipher text is created. Message replication can be easily detected by an adversary who is a bad link in every communication. In this paper, propose to use a 5d chaotic system combined with GOST block cipher to create a new secure Web of Things (WoT) cryptography system. The 5D chaotic system was used to generate chaotic random keys used in GOST algorithm to provide proper security with as high hardness randomly enhances the NIST fifteen statistical tests and modifies key schedule as security operations.
Highlights
A variety of experiments have been carried out to discourage third entities from accessing data through contact
In [41], this study proposed to encrypt WSN’s message digester MD, a new encoding scheme known as Chaotic Block Cipher (CBC)
Many tests are conducted using the proposed approach to encrypt/decrypt sensing data by using the characteristics of GOST block cipher and chaotic system, ensuring that the software and hardware encryption and decryption scheme is fast and easy to implement for resource-controlled devices such as smart devices and wireless nodes
Summary
A variety of experiments have been carried out to discourage third entities from accessing data through contact. Chaotic systems have important features that ensure the mechanism is extremely safe and resilient to cryptographic attacks Due to their capability to attain diffusion-based confusion results, various chaos-based encryption algorithms were investigated and implemented in any cryptosystem [7]. The aim of this research in this paper, suggests a new WoT cryptography algorithm according to GOST and novel 5d chaotic system. It can provide high security at a very fast encryption rate and can be implemented by software and hardware.
