Improved Cryptographic Technique by Square Matrix with Column Cells and Uniform Point Crossover on Binary Field

Abstract: A new cryptographic algorithm is introduced. This technique uses three keys for encryption and decryption. A nearby square matrix with few column cells is used to place the input plain text in a unique manner. The left diagonal‟s positional value will be the key-1 with that key intermediate cipher text is produced. A 7-digit random number is generated as key-2. According to the digits of key-2 the section division, the block division process and the crossover point is finalized. Uniform point crossover is applied on the binary field of intermediate cipher text to produce complex final cipher text.
