Generating Random Binary Bit Sequences for Secure Communications between Constraint Devices under the IOT Environment

The researchers found random numbers beneficial to implement a secure IoT environment. To secure the communications between constrained devices, researchers can use either true random number generators (TRNGs) or pseudorandom number generators (PRNGs) to generate the secure key. Encryption or decryption of the plain text and the mutual authentication between devices uses these keys. PRNGs are highly dependable on TRNGs for the perfect randomness because the randomness of the natural sources or TRNGs is not traceable. Although TRNGs are much safe to generate random numbers, programmers write codes for pseudorandom number generation, commonly known as PRNGs. These PRNGs should use less complicated methods for use in the IoT environment. Authors are writing the programs to generate random numbers independently, without any hardware interruption. In this paper, authors are going to use these concepts to form a new lightweight mechanism for the generation of cryptographically secure random binary bit sequences. Here authors are trying to incorporate the goodness of every flavor at one platform.
