Abstract
Data security is a crucial concern that ought to be managed to help
protect vital data. Cryptography is one of the conventional approaches for
securing data and is generally considered a fundamental data security
component that provides privacy, integrity, confidentiality and authentication.
In this paper, a hybrid data security algorithm is proposed by integrating
traditional RSA and Gaussian interpolation formulas. The integration raises the
security strength of RSA to the fifth degree. The Gaussian first forward
interpolation is used to encrypt the ASCII values of the message after which the
traditional RSA is used to encrypt and decrypt the message in the second and
third levels. The last stage employs Gaussian backward interpolation to decrypt
the data again. The integration helps to cater to the factorisation problem of the
traditional RSA. Comparative analysis was performed using four different
algorithms: RSA, SRNN, two-key pair algorithms and the proposed algorithm.
It is proven that when the data size is small, the encryption and decryption
times are lower for the proposed algorithm but higher when the data size is big.
