Abstract

Operations Research is a scientific discipline that can be used to help make decisions in all fields. In the military field, the application of operations research is very much so that every officer must be able to apply it in carrying out his duties. Indonesian Navy officers received education about operations research, especially the analytic hierarchy process when they attended the Staff and Command College. A total of 20 student officers were examined to find out the difficulties they faced in solving problem solving for the analytic hierarchy process material through written answers to questions and in-depth interviews using Polya's problem-solving steps. The results obtained are that all officers did not experience problems at the time of problem identification. However, almost half of them experienced problems when planning solutions, carrying out calculations and conducting reviews. The recommendation submitted is to use a software application so that the calculations are correct and fast.

Abstract

Information security is a crucial aspect in today's digital era, where increased connectivity and data exchange involves a high risk of denial of services attacks. Increasing cybersecurity and privacy issues require more effective defense mechanisms to counter these threats. This research was conducted through design formulation using game theory for denial of service attacks. First scheme , use Bayes' theorem to determine the probability of a DDoS attack. The probability is equal. The probability of attack and defense is 50-50. Second scheme, one of players is dominan. A game theoretic framework as an approach to find out the possibility of denial of services between pairs of attacking/defending nodes using a Bayesian formulation. Game modeling can propose for developing better mitigation and detection approaches.

Abstract

Triple DES (Triple Data Encryption Standard) merupakan salah satu algoritma simetris pada kriptografi yang digunakan untuk mengamankan data berupa pesan teks dengan cara menyandikan pesan teks. Proses yang dilakukan dalam penyandian datanya, yaitu proses enkripsi dan proses dekripsi. Algoritma triple DES adalah suatu algoritma pengembangan dari algoritma DES (Data Encryption Standard). Perbedaan DES dengan triple DES terletak pada panjangnya kunci yang digunakan. Pada DES menggunakan satu kunci yang panjangnya 56- bit, sedangkan pada triple DES menggunakan tiga kunci yang panjangnya 168-bit (masing- masing panjangnya 56 bit). Pada penelitian ini penggunaan enkripsi 3Des akan dikombinasikan dengan Base64 untuk mengamankan informasi berupa teks dengan Bahasa pemograman Python
