Perancangan Program Aplikasi Kriptosistem Menggunakan Algoritma Frog dan Fungsi Hash MD5

Abstract

Problems integrity and confidentiality of data has become an important aspect of information systems , as more and more crimes against computers that arise, as a result of these technological advances . Until now, more and more toward computer crimes that occurred , but acknowledged it is difficult to avoid the crime. Therefore , the thing to do is to avoid the occurrence of a crime against the computer . Required a safeguard against software, so that the data contained on the computer more secure . It has therefore been made to the software security program , which is expected to be used to ensure the confidentiality and integrity of data . The design was made by using two algorithms , which is a fusion of two algorithms , MD5 and Frog with a symmetric key . By using a combination of two algorithms is expected that the program created will provide security to the data . The process of data encryption in the program will also prevent intrusion by people who do not have access rights . Application program cryptosystem using FROG algorithm and the MD5 hash function can be implemented in accordance with the technical specifications of design designed. This application is built using Microsoft Visual Basic 6.0, and Microsoft Visual C + + . Overall the module has.
