Triplicative Cipher Technique

Cryptography, the study of “secret writing”, is used today to protect the valuable data on internet and extranet. In computer networks assets like servers, user accounts, password and many more are critical and need protection. Cryptography serves the sole purpose of information security i.e., “to protect assets”. Main aim is to achieve the three security goals- confidentiality, integrity and authenticity. To achieve these securities this paper proposes a robust encryption technique by considering alphabetical, numerical and alphanumerical data. It is purely a mathematical cryptography technique which comprises AES standard consisting of mathematical operations like addition, subtraction, multiplication and conversion methods.
