Sooner Lightweight cryptosystem: Towardss Privacy Preservation of Resource-Constrained Devices

Abstract

The use of cryptosystem became popular because of the increased need for exchanges across untrusted medium especially Internet-enabled net works. On the basis of application, several forms of cryptosystems have been developed for purpose of authentication, confidentiality, integrity, and non repudiation. Cryptosystems make use of encryption schemes that convert plaintext to ciphertext in diverse areas of applications. The vast progressions in the Internet of Things (IoT) technology and resource-constrained devices have given rise to massive deployment of sensor devices and growth of services tar geted at lightweight devices. Though, these devices support a number of ser vices, they require strong lightweight encryption approaches for privacy protec tion of data. Existing lightweight cryptosystems fall short on the expected pri vacy levels and applicability in emerging resource-constrained environment. This paper develops a mathematical model for a sooner lightweight crypto graphic scheme based on reduced and hardened ciphertext block sizes, hash siz es and key sizes of traditional cryptosystems and Blockchain technology. Thereafter, the hardening procedure offered by the RSA homomorphic encryp tion was applied for the purpose of generating stronger, secure and lightweight AES, and SHA-3 in order to deal with untrusted channels exchanges. The pro posed Sooner is recommended for adoption in public Blockchain-based smart systems and applications for the purpose of data privacy at 95% likelihood.
