IMPLEMENTASI ALGORITMA KRIPTOGRAFI PERMUTASI SUBSTITUSI XOR DINAMIS PADA PROSES DOWNLOAD FILE
Abstract
Currently, Internet is growing so rapidly that almost anyone can use it in many areas of life. With internet users can quickly get the information they want. In the process of getting the data there are times when the data can be retrieved by others who are not eligible for example hackers. Therefore we need a method that can be used to secure our data that can not be retrieved by unauthorized parties. One method I use to secure data is cryptography using permutation substiutsi xor (PSX) dynamically during the process of getting data from a computer server of an agency. The encryption process is done on the server side during the process of downloading the desired file and dsimpan takes place on the client computer. To open the data required applications installed on the client computer. So that not everyone can use it and the result is that data can be obtained safely.References
