摘要：Data encryption technique is the art of cryptology protecting valuable information or data by transforming it into an unreadable scrambled text. Cryptography algorithm is a mathematical technique used to preventing or safeguard messages from unsolicited access. In the current digital environment, public, private financial institution�s data transactions conducts through open network channel only. Therefore, it is significant to implement cryptography techniques on those financial data to secure valuable things. In many sectors exploiting private algorithms such as DES, AES and public algorithms such as RSA, Diffie-hellman been using in various applications. Public key or Asymmetric key encryption technique has connection with many performance issues such as energy consumption, memory wastage and computational problems etc., Correspondingly, symmetric key algorithm also has a problem of non-repudiation, false modification etc., to overcome the above issues and enhance the confidentiality to make it stronger, hybrid cryptography techniques offered better solution. In short, the hybrid technique uses the combination of two or more encryption algorithms. The proposed hybrid algorithm is combination of enhanced hill cipher algorithm using modulo 37 and using simple positive and negative integer numbers. Many hybrid algorithm follows different logic to provide more security, we proposed here, simple and open design, straightforwardness, computational speed, more privacy. and security compared to existing hybrid encryption schemes.
