One of the most important challenging tasks in transferring data over digital medium now a days is security. Confidentiality, Integrity, and Authenticity are the fundamental principles of information security. Every technique which deals security should be designed to succeed in achieving one or more of these fundamental principles. Coding based Cryptography is one of the research areas in the field of Cryptography. In this paper, a new method has been proposed which deals with a variant encryption scheme using arithmetic addition coding and linear inverse function. Arithmetic addition coding is a technique which divides the input data text into 4x4 blocks and then encodes using a series of simple addition operations. Linear inverse function encrypts the encoded data using a linear invertible equation using prime module with multiplicative inverse. Linear invertible function adds additional level of encryption to the encoded data. This combination giving best encrypted results than the existing method. The performance of proposed method is measured with encryption time and decryption times for various file sizes.
