  • Security, internet connectivity and aircraft data networks
    2006
    Co-Authors: Thanthry Nagaraja, Ali, Muhammad Sabeeh, Pendse Ravi
    Abstract:

    DOI: 10.1109/MAES.2006.1635168Internet connectivity which was in experimental stages only a few years ago is a reality today. Current implementations allow passengers to access Internet for pleasure and in some cases secure VPN access is provided to corporate networks. Several researchers are looking at the possibility of the existence of a total of three networks: passenger network (PN); crew network (CRN); and the control network (CON). Researchers envision an architecture where these three networks will co-exist in an airplane. The available Internet connectivity can be utilized for transporting flight critical information like Cockpit flight data Recorder (CFDR) data, digital flight data Recorder (DFDR) data, Cockpit Voice Recorder (CVR) data, and controller pilot data link communication. In addition, the internet connectivity could also be used for other safety mechanisms like video surveillance and remote control of the flight. Security is one of the major concerns that affect the successful deployment of Aircraft Data Networks (ADN) and other safety features. Several studies have been carried out to secure the network using fJl"ewalls and intrusion detection system but so far no study has focused on securing the communication channel (between the aircraft and the gronnd station) and its impact on the ADN. The scope of this research is to determine the v iability and need of a security mechanism. The research will also focus on the performance of different security architectures and determine their usability in the framework of an ADN.Peer reviewed articl

  • Efficient data storage mechanisms for DAP
    IEEE, 2004
    Co-Authors: Ali, Muhammad Sabeeh, Bhagavathula Ravi, Pendse Ravi
    Abstract:

    The full text of this article is not available on SOAR. WSU users can access the article via IEEE Xplore database licensed by University Libraries: http://libcat.wichita.edu/vwebv/holdingsInfo?bibId=1045954The Cockpit Voice Recorder (CVR) and digital flight data Recorder (DFDR) are the traditional black boxes used in general and commercial aviation aircrafts. These are used to record vital audio and aircraft parameters. Substantial time and monetary expense are incurred after an aircraft accident to retrieve the black boxes and sometimes the Recorders are found damaged and unreadable which further inflates aircraft accident investigation time and expenditures. The CVR typically records the Voice conversations within the Cockpit on 2 (or 4) different channels for a duration of 30 minutes. The DFDR records the aircraft's vital parameters over the entire duration of a flight. The CVR records information in such a way that only the last 30 minutes of Voice is available. As a supplement to the existing CVR/DFDR, the authors present the possible transfer of the acquired Voice, video and data from the airplane to the ground stations. This transfer is envisioned to be carried out by (a) utilizing the available data link being employed for IP connectivity between the airplane and the ground station to stream live data, Voice and video traffic to the appropriate servers on the ground, or (b) storing the data, Voice and video streams locally within the airplane and downloading them to the appropriate servers on the ground station. Since numerous aircraft are expected to be in-flight at any given point of time, the management of the downloaded Voice and data within the ground stations could easily become a scalability issue. While file transfer mechanisms like FTP provide considerable flexibility in the deployment of DAP, a scalable means of catering to hundreds of airplanes simultaneously would be the adoption of file I/O and block I/O based data transfer mechanisms. Different I/O mechanisms including (a) network file system (NFS), (b) Internet small computer system interface (iSCSI), and (c) enhanced network block device (ENBD) were considered for the current work.Peer reviewed articl

  • IMPLEMENTASI DAN ANALISIS PERBANDINGAN ALGORITMA STREAM CIPHER UNTUK SECURE BLACKBOX Cockpit Voice Recorder
    Universitas Telkom, 2017
    Co-Authors: Fadira Akmal
    Abstract:

    Sistem yang ada pada black box pesawat saat ini hanya sebatas sebagai media penyimpan segala bentuk aktivitas penerbangan. Black box pesawat belum memiliki kemampuan untuk mengirimkan informasi ke tempat lain serta jika ada proses pengiriman informasi, black box pesawat belum memiliki sistem keamanan. Keamanan data merupakan bagian yang sangat penting pada saat melakukan proses pertukaran informasi. Informasi yang dipertukarkan hanya boleh diketahui dan dimiliki oleh pengirim dan penerima yang telah ditentukan. Proses pertukaran tidak boleh melibatkan man-in-the-middle attacker atau pihak yang tidak dikenali oleh pengirim atau penerima. Oleh karena itu untuk menjaga keamanan, kerahasian dan autentikasi data perlu adanya implementasi kriptografi, yang merupakan ilmu dan seni untuk menjaga keamanan pesan. Algoritma stream cipher yang digunakan adalah Dragon yang termasuk ke dalam kategori synchronous stream cipher dalam proses enkripsi dan dekripsi. Dragon merupakan algoritma kandidat eStream Project, yang dapat diimplementasikan pada software dan hardware. Pada penelitian Tugas Akhir ini, dirancang suatu sistem pengamanan data suara pada Cockpit Voice Recorder, dengan cara dienkripsi. Lalu memberikan hak akses secara aman untuk didekripsi oleh orang yang memiliki hak akses data tersebut. Hasil akhir yang didapat dari penelitian ini akan di uji performansi terkait waktu proses enkripsi dan dekripsi, avalanche effect, dan keutuhan data. Sehingga didapatkan satu algoritma yang memiliki sistem keamanan yang layak untuk Cockpit Voice Recorder. Keyword : Stream Cipher, dragon, Cockpit Voice recorde

  • a mathematical cross correlation for time alignment of Cockpit Voice Recorder and flight data Recorder data
    Journal of Accident Investigation, 2006
    Co-Authors: J A Gregor
    Abstract:

    A new method is described for performing timing correlations between flight data Recorder (FDR) and Cockpit Voice Recorder (CVR) information. This method involves the use of the cross-correlation function to search the typically larger FDR data file for a best match to the event pattern present in the CVR data file. The results of this search give a first-order estimate of the time differential between identical events as recorded on both units. A simple curve fit may then be employed to obtain a general conversion from time as represented in the CVR and time as represented in the FDR.
