IMPLEMENTASI ALGORITMA KRIPTOGRAFI AES 128BIT DAN ELGAMAL UNTUK PENGAMANAN E-MAIL PADA BANDARA INTERNASIONAL SULTAN MAHMUD BAHARUDDIN II PALEMBANG

Abstract

Document security is one of the most important things in the exchange of data and information, especially
the exchange of data using email media, because there are many threats when the process is done. Data
security, especially for text documents is very important. Because the text of messages that are sent is
sometimes a private and confidential message, so the confidentiality of messages becomes very important.
Document security at SMB II Airport is very important such as employee data from head office as well as
company documents that should not be known by outsiders. The document is a very secret document, if
the important documents of the company fall into the hands of irresponsible, then there are parties who
will be very harmful in the incident. Therefore, a better level of security is required with the development
of an encryption application or message to be sent. Utilize the email media shown to help resolve
document security issues, so that third parties can not know the contents of the information or messages.
Utilization of AES 128bit algorithm combined with Elgamal algorithm to generate an information
encoding application in improving document security.
