Data Security using Compressed Classical Technique

Throughout the time of years, an elaborate set of protocols and mechanisms has been created to deal with cyber security. Cryptographic algorithm plays an important role in the vast domain of cyber security systems. While transmitting the data to third party it is possible to be victim of being hacked by an attacker. The proposed system is a new security model which utilizes the concept of hybrid encryption and decryption to provide a secure and protected environment. In the proposed model, data owner performs some mechanism and encrypts the data to make it hidden from attacker and provide only authorized user with the corrcsponding decryption key to retrieve the original data. The utilization of Hybrid encryption and idea of key cryptography is utilized as it is more efficient and makes data more protected from any malicious activity. The proposed system contributes in the area of classical cryptography by providing a modified and expanded version of some cryptographic algorithms with the knowledge of mathematics and computer science. To build the quality of the traditional encryption methods, the proposed modified algorithm uses the concepts of transposition ciphers and randomized substitution techniques to create a cipher text which is which is almost difficult to decipher.
