Abstract

Our current life surrounded by cryptography. Starting from the transaction at the ATM machine, a conversation through mobile phones, accessing the Internet, to enable the missile was using cryptography. Once the importance of cryptography for Information Security (Information Security), so if talk about security issues associated with computer use, it will not be separated from the cryptography. Cryptography is also used in the process of sending email. If an email is sent through the public network then the security level is very risky. Theft techniques of information from an email will increasingly from day to day. One of them is the concept of Man - In - The Middle. Use of Cryptography will help give our email information security. Although the attacker or the Man - In - The Middle managed to get the text that we send, but can not get any information obtained since the text had been encrypted before. Chipertext obtained can only be opened by the party who has a private key (decryption key). One algorithm used for encryption and discussed in this final project is the ElGamal algorithm. This algorithm emphasizes the discrete algorithm problem. With these problems then chipertext ElGamal encryption result will be very difficult to decrypted.
