ABSTRACT: Cryptography is the study of encoding and decoding secret messages, videos, audio and images. In this paper a study on modified encryption and decryption technique is done to cryptanalyst by using Greek Alphabets. Addition, Subtraction and Multiplication tables of mod 24 for Greek Alphabets are created. Using Shift transformation, Julius Caesar method, Affine transformation, Digraph, Enciphering matrices, Knapsack problem, new ciphertext codes are generated.
