Abstract

For various reason data security and confidentially are needed. One way to improve data confidentiality in data communications by modifying the classic cryptographic algorithm into a difficult algorithm to solve. Vigenere Cipher is one of the most complicated classical cryptography algorithms to be solved, because it uses substitution techniques and keywords. Although so Vigenere Cipher still have weaknesses and the length of the keyword can be solved by using the kasiki’s method. This paper discussed about modification of Vigenere Cipher, that is changing the contents of Vigenere square to decimal numbers 1…26, which then the decimal symbol of the encryption result are coded RGB color, so the final encryption result of the modification of Vigenere Cipher in this paper is a color image, so it becomes very difficult to solve. Because a cryptanalyst does not necessarily think the color image is an encryption that should be solved.
