%X Security is preferred in information systems, especially in the exchange of  data that are important or confidential. The information will be given to the party  entitled to such information should really be kept, do not fall into the hands of  others who do not have a right to that information. One of the efforts to preserve  and guarantee the security of information or data is to use cryptographic  techniques. Cryptography is the art and science of hiding information from third  parties.  Advanced Encryption Standard (AES) and Twofish are two examples of  some symmetric cryptographic algorithms based on block ciphers. Both systems  use the same key of symmetric cryptography, 128-bit block size, and 128, 192,  256 key length. This study aims to analyze the performance comparison AES and  Twofish in speed encryption and decryption process, the value of avalanche  effect, and the exhaustive key search. This comparison is facilitated by DP –  Multicrypt software.  Based on the results of this study concluded that a process of encryption  and decryption algorithm is faster than the AES algorithm Twofish, because AES  has a simpler structure. While the Twofish algorithm tougher than AES against  cryptanalysis because it has a larger avalanche effect. And exhaustive key search  on both the algorithm generates a value of loading very large, this causes said  second algorithm resistant to cryptanalysis.
