Data Security Optimization using Hybrid Cryptography -An Empirical Study of Hybrid Encryption using Symmetric, Asymmetric and Hashing Algorithms

This research study proposes Hybrid Encryption System using public key, private key and hashing algorithms in unison. Hybrid encryption is a mode of encryption that amalgamates two or more encryption systems. It integrates a combination of symmetric, asymmetric and hashing encryption to benefit from the strengths of each form of encryption. This paper presents a provably three way secured data encryption system, which addresses the concerns of users privacy, security, and integrity. In the proposed system, three different encryption algorithms have been used in the encryption sequence. One is private key cryptography based on the simple symmetric algorithm and another one is public-key cryptography based on a linear block cipher and a hashing function algorithm (Message-Digest). This cryptography algorithm provides more security and makes the encryption further robust compared to the existing hybrid algorithms.
