Abstract

The network security has a very important role at this time, because the development of network technology caused the greater threat faced. These conditions create a lot of opportunities in the development of computer applications but also makes threats to alter and steal data. The purpose of this research is to analyze the comparison between cryptography method and AES from encryption and description point of view, crypto component, iteration, algorithm character, transformation and key. The category of this research is cryptography algorithm comparison between DES method (data encryption system) and AES (advanced encryption). This research is to compare and analyze DES and AES method by examining sample based on the structure of encryption and description, iteration, algorithm character and transformation. The result of the research reveals: 1) encryption and description analysis uses DES program which is simpler than AES program. DES data is processed by four steps without iteration and the result is alphabet form whose number as many as the analyzed alphabets. ; 2) The result of encryption and description AES analyses uses the cryptography algorithm AES Rijndael with 128 byte key size, it has long iteration (9 iteration). The long steps make encryption and description are more safe ; (3) the usage of cryptography AES Rijndael with 192 and 256 byte key size is more safe and it produces longer and complex iteration so that it is hard to be pirated by hacker or irresponsible hand.
