Abstract

This paper is a contribution to the field of network security.It states a new technique named “Symbol Shifting Cipher” for encryption and decryption to prevent unauthorized access of data.It states a new encryption technique for secure data transmission.This paper describes that the alphabets, digits and space between the words of the plain text are replaced by their corresponding ASCII values and by some assigned symbols.These symbols are then represented in (nXn) matrix where each elements of the matrix are shifted to their corresponding columns.Then the elements of the (nXn) matrix are written in a sequence and again are replaced by corresponding ASCII values and alphabets, digits, space to create the final cipher text.This paper also compares this new cipher technique with some others renowned cipher techniques (such as Ceaser cipher, Vernam cipher) with respect to their complexity of the techniques and the probability to break the cipher code.
