Abstract

Vehicular Ad-hoc Network (VANET) merupakan teknologi yang mendukung pertukaran data antar kendaraan di jalan raya. VANET menggunakan jaringan wireless berbasis ad hoc yang memungkinkan terjadi serangan, seperti Black hole dan Worm hole attack. Black hole attack adalah serangan yang dilakukan suatu malicious node dengan menjatuhkan paket data yang diterima, sedangkan Worm hole attack dilakukan dengan mengubah isi paket data. Kedua serangan ini dapat mempengaruhi performa routing protocol yang digunakan dalam komunikasi antar kendaraan. Kedua serangan tersebut dapat diatasi jika tiap node dapat mendeteksi jika ada malicious node di sekitarnya, sehingga tiap node tersebut tidak meneruskan paket data ke malicious node. Black hole attack dapat dideteksi dengan melakukan pemantauan terhadap arus pertukaran data pada tiap node, sedangkan Worm hole attack dapat dideteksi dengan menggunakan digital signature. Tugas akhir ini mengimplementasikan Elliptic Curve Digital Signature Algorithm (ECDSA) sebagai algoritma digital signature yang dilampirkan pada tiap paket data. Pada tugas akhir ini didapatkan routing protocol yang menerapkan pemantauan arus pertukaran data dan digital signature pada tiap paket data yang dikirimkan mempunyai performa yang lebih baik jika dihadapkan dengan Black hole dan Worm hole attack dibandingkan dengan routing protocol yang tidak menerapkannya, dibuktikan dengan peningkatan packet delivery ratio hingga mencapai 60.61% yang pada routing protocol tanpa modifikasi sebelumnya turun drastis. =========================================================================== Vehicular Ad-hoc Network (VANET) is a technology enabling data exchange between vehicular on roads, in order to support Intelligent Transportation System. VANET use an ad-hoc base wireless network that can be attacked by several attacks, such as Black hole attack and Worm hole attack. Black hole attack is an attack conducted by dropping data packet that has been received, meanwhile Worm hole attack conducted by tampering the data packet. Both attacks can affect the performance of the routing protocol used in vehicular communication. Both attacks can be overcome if each node can detect the malicious node around them, so they do not forward the data packet to malicious node. Black hole attack can be detected by recording the data packet exchange traffic in each node, meanwhile Worm hole attack can be detected by attaching digital signature on each data packets that will be sent. This thesis implements Elliptic Curve Digital Signature Algorithm (ECDSA) as the digital signature algorithm attached to each data packets that will be sent. In this thesis, it is obtained that the routing protocol which applies data packet exchange traffic recording and the digital signature on each packet that will be sent has better performance than the routing protocol which does not, proven by the increase of packet delivery ratio until 60.61%, which value has dropped dramatically when using the original routing protocol before.
