MODIFIKASI VIDEO ENCRYPTON ALGORITHM UNTUK MENINGKATKAN TINGKAT KEAMANANNYA
Abstract: Nowadays,
information exchange through electronic media becomes one of communication ways
which is frequently used for communicating with each other. Since there are
information which have to be kept secret during the transmission while the
communication line can not prevent the information against the eavesdropper,
impersonating, man in the middle attack, etc, then the way to keep the
information secret should be considered. One of methods for keeping the
information secret is cryptography. There are many cryptosystems which have
been proposed for preventing information against attacker. Two of them are
Video Encryption Algorithm (VEA) and Data Encryption Standards (DES) which can
be used for encrypting information in either visual or text. However, both cryptosystems
still have weaknesses. VEA is less secure than DES, while DES needs more time
for processing the video/picture encryption compared with VEA. This paper
introduce a cryptosystem for encrypting video/picture which needs less time for
encrypting video/picture but has equal security as DES. In other words, the
proposed cryptosystem is more secure than VEA. This cryptosystem is a
development of both DES and VEA. Based
on analysis we demonstrated that our approach confirmed those above advantages.
