Abstract:

Routers are the key equipments connecting Wan, LAN and Internet network, and are the main part of the Internet. The reliability and security of routers is very important to the network performance and information data security. The analysis and research on the technologies of router security and protection is the core issue for network security. This paper mainly aims at providing a series of test and analysis on the vulnerabilities of Tenda wireless routers. Technically, it’s very difficult to crack the WPA /WPA2 wireless encryption. In this paper, we use the related vulnerabilities of wireless routers, and open Wifi Protection Setup (WPS) and Quick Security Settings (QSS) to get router PIN code, which can help us bypass the WPA/WPA2 encryption and, realizesd the router attack.

Abstract:

Wi-Fi protected access (WPA) has provided serious improvements over the now deprecated wired equivalent privacy (WEP) protocol. WPA, however, still has some flaws that allow an attacker to obtain the passphrase. One of these flaws is exposed when the access point (AP) is operating in the WPA personal mode. This is the most common mode, as it is the quickest and easiest to configure. This vulnerability requires the attacker to capture the traffic from the four-way handshake between the AP and client, and then have enough compute time to reverse the passphrase. Increasing the rate at which passphrases can be reversed reduces the amount of time required to construct a repository of service set identifiers (SSIDs) and passphrases, which can increase the chances an attack is successful, or, alternatively, reduce the difficulty of auditing a wireless network for security purposes. This work focuses on creating an field programmable gate array (FPGA)-based architecture to accelerate the generation of a WPA/WPA2 pairwise master key (PMK) lookup table (LUT) for the recovery of the passphrase, with special emphasis on the secure hash algorithm-1 (SHA-1) implementation. PMK generation relies heavily on SHA-1 hashing and, as this work shows, an optimized SHA-1 implementation can achieve up to a 40 × speedup over an unoptimized implementation when generating PMKs.

Abstract:

Cloud based libraries connect individuals to on-demand information needed to solve problems, expand frontiers and re-shape the future. In the era of disruptive computing, a digital library model using cloud computing Infrastructure as a Service (IaaS) is proposed. The proof of concept is used to demonstrate the viability of deploying and running virtualized digital library in Nigerian higher institutions. Lean design phases are used in developing the library application program interface (API) as well as the network design. Programming languages such as CSS, JavaScript, PHP and MYSQL are used for the API integration while demonstrating a hypervisor based server infrastructure on a Wi-Fi hotspot. For access control on the network, a network IP address configuration based on classless inter-domain routing (CIDR-192.168.0.0/24) is applied while using TP-Link 3G/4G Wireless N-Router (TL-MR3420) access point for 300Mbps wireless connectivity. Front-end vulnerability threats are addressed during the coding phase while demonstrating improvement on the level of services provided for resource accessibility and management. A faculty wide scenario in Federal University of Technology is used as a validation case study. The proposed system is flexible, offers robust security support with 64/128bit wired equivalent privacy (WEP), WPA/WPA2 and WPA-PSK/WAP2-PSK encryption standards. Cloud-DLT eradicates the challenges and inconveniences associated with accessing and managing the library resources. The work highlighted its usefulness and implications to academics and students in the next few years.

Abstract:

Pada sistem jaringan wireless sering terjadi masalah yaitu salah satunya keamanan wifi yang menggunakan keamanan WPA, WPA2, dan WEP yang ditinjau dari vulneravility. Karena teknologi wireless memanfaatkan frekwensi tinggi untuk menghantarkan sebuah komunikasi, maka kerentanan terhadap keamanan juga lebih tinggi dibanding dengan teknologi komunikasi yang lainnya. Sekarang ini sudah banyak tool aplikasi exploit wifi yang di gunakan oleh hacker atau attacker salah satunya tool Reaver dan tool Aircrack dalam system operasi kali linux, dari kedua tool tersebut peneliti ingin mencari perbandingan dari tingkat availability. Karena kedua tool tersebut menrut peneliti adalah tool yang terbaik saat ini. Dalam penelitian ini parameter yang akan di ukur adalah seberapa capat waktu ackes ke jaringan wifi, seberapa cepat menembus keamanan wifi, dan berapa besaran biter yang di dapat. Dari hasil penelitian dan uji coba maka di simpulkan bahwa untuk segi kecepatan aircrack yang lebih cepat untuk memecah password karena bruteforce dengan wordlist, reaver langsung scanning password wifi namun memakan waktu sangat lama hampir 13 jam untuk waktu terlama Kata kunci: Tool Reaver dan Aircrack, Avability dan vurnability bruteforce, wordlist

Abstract:

Jaman sekarang keamanan pada sistem jaringan komputer sudah sangat berkembang pesat, selain itu juga jaringan berbasis wireless sudah sering sekali kita temukan, jaringan tersebut juga harus dikombinasikan dengan keamanan yang baik. Pada saat ini pembuatan kemanan jaringan menggunakan Wireless sudah banyak ditemukan di sekitar kita tetapi dalam situasi dan kondisi pengamanan jaringan wireless yang banyak digunakan saat ini seringkali dapat dikatakan masih belum aman. Pasalnya, keamanan yang saat ini sering sekali kita temui yaitu seperti WPA, dan WPA2. hal ini masih dapat dikategorikan tidak aman dikarenakan keamanan yang banyak digunakan saat ini masih dikategorikan mudah dalam upaya pembobolan. Untuk itu diperlukan keamanan yang mumpuni dan mudah dalam proses manajemen user. Maka dari itu penulis berencana mengembangkan keamanan jaringan menggunakan sistem authentikasi menggunakan LDAP server. Digunakan sistem authentikasi dinilai lebih aman, dikarenakan setiap pengguna akan dilakukan pengecekan identitas pada proses login ke dalam sebuah sistem jaringan. LDAP digunakan sebagai protocol direktori servis, dimana semua data user akan disimpan didalam LDAP sehingga akan lebih mempermudah dalam proses management user.. Pembuatan server menggunakan Ubuntu 14.04 (LDAP) dan Ubuntu 12.04 (Radius), dalam pembuatan server ini kedepannya akan lebih memudahkan untuk pengamanan jaringan pada user akun pengguna. Karena itu, authentikasi menggunakan LDAP menjadi pilihan penulis untuk mengatasi masalah keamanan dan manajemen user pada jaringan komputer karena dinilai lebih mudah, aman dan efisien dalam hal keamanan dan pengelolaan user dalam sebuah jaringan.
