A New Symmetric key Cryptographic Algorithm for Unicode Compliant Bangla Characters

Abstract

Cryptography is the discipline that embodies principles, means, and methods for the transformation of data in order to hide its information content, prevent its undetected modification and/or prevent its unauthorized use. Now-a-day most of the organizations are increasingly dependent on electronic data for various purposes. Since data travels electronically the alarming issue is the security. Cryptographic algorithms can play vital role to resolve this issue. There are two basic types of cryptography: secret/symmetric key and public/asymmetric key. Symmetric key algorithms are the quickest and most commonly used type of encryption. Here, a single key is used for both encryption and decryption. This paper describes a new symmetric key algorithm which is applied on the Unicode compliant bangle characters. Algorithms for both also described along with the drawbacks. Since government of Bangladesh is planning to introduce e-governance this kind of cryptographic algorithm should be applied to secure various important and vital data. As per as literature are concerned, this kind of work for Unicode compliant bangle characters has not been done yet i.e. this could be the pioneer work.
