Modify Speck-SHA3 (SSHA) for data integrity in WoT networking based on 4-D chaotic system

Abstract

WoT has become one of the important fields that accompanied the development of technology in the present day, so that its income in all areas of work, including (industrial, agricultural, medical, industrial, etc.). This proliferation generated fears among users of the growing use of WoT without providing safe ways to preserve the information generated by its devices. So, many ways to maintain the security of data as well as integrity, through the use of light weight speed algorithms to encrypt and to validate the parameters that may be used in this area. In the field of information authentication, many algorithms have emerged that help to ensure the authenticity of information generated when sent from physical sensors to the user environment. These include SHA-1, SHA-2, SHA-3, etc. In WoT, the speed of encryption and authentication must be an important requirement and a duty to ensure the validity of the information and to continue monitoring the data. Therefore, providing fast algorithms is an important requirement to be provided with WoT.
In this paper, a modification of the SHA-3 algorithm will be introduced by replacing the KECCAK function with another very fast algorithm which is SPECK which is produced a very fast algorithm with a reliable strong level of security in the data validation process produced by sensors.
Also, the extended logistic system will be used to generate the initial values that the SHA3 algorithm uses to make these values unknown and which the intruder cannot guess or recognize.
