Students will study methods of encryption and decryption, such as Substitution, Caesar Cipher and Shift Cipher. Classroom ... WebJul 9, 2024 · cryptography technique Make a matrix out of the numbers. Because the secret key will be multiplied by the created matrix, it has the given property. If A and B are two matrices represented by AB, then the number of columns in the first matrix must match the number of rows in the second matrix, i.e., if A is mn and B is np, then C=AB is defined ...
WebMar 11, 2024 · Cryptography helps protect data from being viewed, provides ways to detect whether data has been modified, and helps provide a secure means of communication over otherwise nonsecure channels. For example, data can be encrypted by using a cryptographic algorithm, transmitted in an encrypted state, and later decrypted by the intended party. ... Webmatrix is used to encrypt the messages, and its inverse is used to decrypt the encoded messages. It is important that the key matrix be kept secret between the message …

It was first … WebWe start by writing out the keyword as a matrix and converting this into a key matrix as for encryption. Now we must convert this to the inverse key matrix, for which there are several steps. The keyword written as a matrix. The key matrix (each letter of the keyword is converted to a number).
WebBreak the word in size equal to key matrix. Now convert the word matrix in number matrix. Now find the cipher matrix by using this formula: C = KP mod 26 Here C = cipher matrix K = key matrix. P = word matrix now transform the cipher matrix into word matrix. Follow the process for the whole data set. Example: We choose word Apple to transform.
