“…The mentioned functions are unidirectional, so it is impossible to reconstruct the data based on the hash itself. This means that the whole message that has been signed [61,62] must be sent with the electronic signature.…”

The rapid development of Internet of things (IoT) technology has made the IoT applicable in many areas of life and has contributed to the IoT’s improvement. IoT devices are equipped with various sensors that enable them to perform the tasks they were designed for. The use of such devices is associated with securing communication between devices and users. The key stages of communication are the processes of authentication and the process of agreeing on session keys because they are the basis of the subsequent communication phases. The specially designed security protocols are used to secure communication. These protocols define the course of communication and cryptographic techniques employed for securing. In this article, we have reviewed the latest communication protocols designed to secure authentication processes and agree on session keys in IoT environments. We analyzed the proposed protocols’ security level, vulnerability, and computational and communication costs. We showed our observations, describing the requirements that a secure protocol should meet.

“…Block encryption algorithms belong to an important branch of symmetric cryptography and have played a crucial role in information security, such as authentication and encryption in wireless networks [7], [8], terminal authentication in mobileto-mobile scenarios [10], [11], and secure integration of IoT and cloud computing [2], [10], [12]- [14]. Shannon conducted an early investigation of block encryption algorithms [15].…”

A Complexity-Reduced Block Encryption Algorithm Suitable for Internet of Things

The Internet of Things (IoT) poses stringent requirements on service quality and security strength. A highly reliable encryption algorithm with low complexity is required to ensure information security. Therefore, this paper proposes a complexity-reduced secure and fast encryption routine (SAFER)-Fermat block encryption method that accounts for the confusion and diffusion principles. In particular, a novel diffusion layer that exploiting the Fermat number theory transform is proposed, while the confusion layer remains unchanged as the SAFER algorithm. We also propose two data record structures to accommodate the two layers and deal with the overflow issue. The proposed scheme only considers the integer operation, the inclusion of multipliers in our study is no longer necessary, thereby resulting in low complexity and lightweight encryption method. Therefore, the proposed encryption method is advantageous for power-limited IoT devices. The simulations demonstrate that the proposed encryption method maintains the security of the SAFER++ method but requires fewer computations.INDEX TERMS Internet of things, block encryption, Fermat number theory transform, computational Complexity.
