IMPLEMENTASI NETWORK ACCESS CONTROL PADA JARINGAN EEPIS

Belakangan ini, pencurian identitas pribadi melalui media internet semakin marak. Berbagai cara bisa digunakan misalnya melalui phishing, email scan ataupun menggunakan piranti yang sanggup melacak gerak-gerik kebiasaan user ketika mengakses situs-situs web di internet. Kebocoran informasi ini tidak hanya terjadi secara personal tapi juga dapat terjadi secara korporat. Yang mana tidak tertutup kemungkinan kebocoran itu datang dari orang dalam sendiri. Karena itulah diperlukan adanya pengaman jaringan diantaranya dengan menggunakan metode NAC (Network Access Control). Dengan menggunakan metode NAC, seorang administrator jaringan dapat mengontrol dan mengamankan jaringannya dari aksi para user yang tidak bertanggung jawab dengan cara mengisolasi komputer user tersebut dari koneksi jaringan. Dalam pengerjaan tugas akhir ini, terdapat sebuah komponen tambahan yang digunakan, yaitu SNORT NIDS. NAC dapat dikembangkan lebih lanjut dengan menambah komponen-komponen pendukung lain. Komponen-komponen tersebut diantaranya adalah hping, nmap, nessus, ethereal dan masih banyak lagi. Dengan NAC ini diharapkan keamanan dalam jaringan akan semakin terjami

Implementasi Algoritma ECDSA untuk Pengamanan E-Mail (Verifikasi Keaslian Pesan)

This final project is discussed about implementation of digital signature on email delivery with java programming language. Digital signature is one of the cryptographic security services that provide assurance to the recipient of the message (receiver). Given the assurance that the sender of the message is the sender, not a third party (eyesdropper) and received messages are genuine. Elliptic Curve Digital Signature Algorithm (ECDSA) is one method of digital signatures on Elliptic Curve Cryptography (ECC). ECC is a public-key cryptography using the Elliptic Curve Discrete Logarithm Problem (ECDLP) as the basic math. ECDLP used is Q = kP, where Q and P are the points on the elliptic curve of F2m Finite field and k is positive integers. This final project provide an email client application that integrated with ECDSA algorithm, so it can be able to provide digital signature on sent message, to verify the digital signature on a received message, and give a warning if the verification fails, which means received email was not genuine

IMPLEMENTASI GRID COMPUTING DENGAN MENGGUNAKAN PENGALAMATAN IPv6

Untuk menghasilkan karya yang lebih dibutuhkan juga perangkat komputasi yang setara dengan karya tersebut. Habisnya IPv4 valid juga menjadi kendala tersendiri di era sekarang. Implementasi grid computing dengan menggunakan pengalamatan IPv6 menjadi solusi dari masalah yang ada. Grid Computing mampu melakukan komputasi dalam skala besar yang terdistribusi dan terpisah secara geografis. Grid Computing diimplementasikan pada 9 komputer yang membentuk 1 server dan 2 cluster dimana semua node menggunakan pengalamatan IPv6. Implementasi cluster menggunakan openmpi, job scheduler menggunakan condor, dan grid engine menggunakan globus toolkit. Perkalian matrik dan Prime sum digunakan untuk menguji coba kecepatan dari sistem grid computing untuk menunjukkan seberapa cepat sistem grid computing mengeksekusi aplikasi (program parallel). Hasil dari uji coba menunjukkan bahwa implementasi openmpi menggunakan IPv6 mampu meningkatkan komputasi lebih dari 5 kali dibandingkan dengan komputasi pada 1 komputer, condor tidak bisa diimplementasikan karena versinya belum memenuhi, dan globus tidak cocok diintegrasikan dengan openmpi. Dua problem tersebut digantikan dengan Portal PHP yang difungsikan sebagai administrasi jobs. Hasilnya, aplikasi Prime Sum dapat dijalankan pada Portal untuk diteruskan ke semua node pada cluster. Kata Kunci : IPv6, Grid Computing, Komputasi Paralle

Implementasi OpenID Pada EEPIS Network

At this time most of the Internet users want the ease and convenience to gain access information that is always an update from the provided information content. On EEPIS network, the content of information is well integrated, but the digital identity facilities that provided on each content requires user to register the digital identity separately. So that each user must properly manage the digital identities on any content that accessible information. Therefore neccessery a system to allow users to manage digital identities owned. The system is a Single Sign-On system using OpenID. OpenID method is a method of open protocols that allow a user using URLs as single digital identities to sign-in into an application. In this final project, the system will be implemented and applied on the EEPIS network in the form of web based application. Future development is expected to implement OpenID authentication system and can assist users in accessing the information content services already integrated in the EEPIS network. Keywords : user, digital identity, OpenID, authentication
