Abstract: In today’s world of Information Technology, information storage and distribution is very important. To secure the data in the network, one need to protect the data using cipher algorithms. This paper presents a novel symmetric block cipher which ciphers data using zig-zag scan patterns. The input data is divided into manageable size of blocks. Each block of data is taken as an input and produces the corresponding cipher text. The data is arranged in a corresponding matrix of manageable size using the zig-zag scan pattern. Then again it is divided into number of 2x2 sub matrices. Cipher text can be retrieved from each 2x2 sub matrix by reading column wise. The Cipher is tested with time complexity, frequency analysis, and with homogeneity testing.
