Kombinasi Algoritma Triple DES dan Algoritma AES dalam Pengamanan File

Abstract

Cryptography is a method to secure data sent from sender to recipient. Triple DES and AES are two symmetric algorithms commonly used in Automatic Teller Machine security and Blackberry Messenger. Since both of these are widely used in society, it is necessary to investigate whether there are weaknesses in the algorithms are and whether there are ways to cope. Key on Triple DES algorithm can be breached by using Differential Attack. For AES, Biclique Attack can reduce the complexity of key from 2128 to 2126.1 (Bogdanov et al, 2011). By combining the methods of Triple DES and AES will get a combined algorithm which is expected to address the weaknesses found in each of these methods.
