- Matrix is one of math study field in linear algebra. Matrix is used since in matrix there are elements arranged in row and column, so operating will refer to each element. Matrix was used to purpose is describing matrix in encryption and decryption in calculating Vigenere code in Unicode. Matrix usage in encryption and decryption at Vigenere code by modulus 65.536, where the modulus refer to the amount of Unicode (Universal Code) characters which has 65.536 characters and the process used matrix operation, which are addition and subtraction. Vigenere code encryption and decryption process in coding message has several phases, they are phases where matrix usage to encode a message. Those phases such as: (1) deciding matrix orde, (2) converting character to value, (3) code placement in matrix element, (4) selecting keys, (5) calculating encryption/decryption, (6) Converting value to character. In encryption and decryption process, there’s a manual matrix calculation, but it can be done using MATLAB programming language, where the programming language is set to read Unicode character code, so the encoded message will be displayed automatically.
