Hybrid Cryptographic Approach for Internet Ofhybrid Cryptographic Approach for Internet Ofthings Applications: A Review

Abstract

Cryptography is described as the study of encrypting or secret writing of data using logical and mathematical principles to protect information. This technique has grown in importance in computing technologies for banking services, medical systems, transportation and other Internet of Things (IoT)based applications which have been subjected to increasing security concerns. In cryptography, each scheme is built with its own respective strength, but the implementation of single cryptographic scheme into the system has some disadvantages. For instance, symmetric encryption method provides a costeffective technique of securing data without compromising security. However, sharing the secret key is a vital problem. On the other hand the asymmetric scheme solves the secret key distribution issue; yet the standalone technique is slow and consumes more computer resources compared to the symmetric encryption. In contrast, hashing function generates a unique and fixed-length signature for a message to provide data integrity but the method is only a one-way function which is infeasible to invert. As an alternative to solve the security weakness

SELAMAT: A New Secure and Lightweight Multi-Factor Authentication Scheme for Cross-Platform Industrial IoT Systems

“…The ECC is utilized to encrypt and transfer the Private Keys as AES Private Keys while AES encrypts the plain text (communication data). The process is applied when an entity needs to encrypt/decrypt the message [ 37 , 38 ]. The encryption/decryption processes are shown in Figure 2 , and the steps are explained as follow: Data are the users’ information, i.e., their identities, passwords, and biometrics.…”

The Dynamic Symmetric Four-Key-Generators System for Securing Data Transmission in the Industrial Control System

“…Mohamed [13] stated that communication devices must provide a strong communication capacity to secure data transmission of various data types to prevent cyber-attacks, including implementing cryptographic methods. As data transmission security, each cryptographic scheme is built with its strengths.…”

“…Mohamed [13] reviewed some of the hybrid cryptographic approach to data transmission security. As for comparison to the proposed method, as shown in Table 3.…”

“…To prevent cyberattacks, any data communication system must include strong data transmission security, perhaps using cryptography [54]. Every cryptographic scheme has its own strengths and weaknesses, and thus the application of a single cryptographic technique has severe shortcomings.…”
