Color Cryptography using Substitution Method

In world of computer network, fears come in many different forms. Some of the most common fears today are software attacks. If we want to secure any type of data then we can use encryption method. All traditional encryption methods use substitution and switch. Substitution methods map plain text into ciphertext in which characters, numbers and special symbols are substituted with other characters, numbers and special symbols. In this paper, we are using a creative cryptographic replacement method is to generate a stronger cipher than the existing replacement algorithms. This method focuses on the replacement of characters, numbers and special symbols with color blocks. This algorithm of substitution is based on Play Color Cipher. Yashvanth. L | Dr. N.
