Abstract
Underwater Acoustic Communication System (UACS) adalah teknologi komunikasi yang banyak digunakan di dunia kemaritiman, namun dewasa ini mulai dieksplorasi untuk kepentingan sistem komunikasi data dengan medium bawah air. Hal ini didorong kenyataan bahwa pemakaian gelombang radio (medium udara) di atas perairan memiliki atenuasi yang lebih besar oleh berbagai faktor peredam, sehingga medium air menjadi alternatif yang cukup potensial. Meskipun demikian, faktor keamanan (security) tetap mejadi pertimbangan penting. Ada banyak metode untuk membangun sistem keamanan komunikasi (termasuk di bawah air), diantaranya dengan teknik kriptografi seperti enkripsi (ciphertext), autentifikasi user dan/atau content, yang kesemuanya membutuhkan secret key yang kuat.
Pada tugas akhir ini, akan diimplementasikan algoritma berbasis Received Signal Strength (RSS) untuk pembangkitan secret key pada sistem UACS sederhana, dengan memilih nilai RSS tertentu untuk kepentingan sebagai link komunikasi hanya untuk dua pihak itu saja, yang tentu berbeda dari nilai RSS link lain. Pembahasan dalam tugas akhir ini meliputi perencanaan link propagasi bawah air, implementasi UACS sederhana di kolam Hidrodinamika ITS, serta pembuatan simulasi pembangkitan secret key-nya. Selanjutnya akan dilakukan analisa dan pembahasan unjuk kerja sistem UACS tersebut.
Dari hasil pengukuran dan pengolahan sinyal, dengan berbagai skema algoritma, dapat disimpulkan bahwa jenis sinyal Tone memiliki nilai Bit Mismatch Rate yang paling kecil, sedangkan jenis sinyal Noise memiliki level Bit Mismatch Rate yang paling besar.
================================================================================================
Underwater Acoustics Communication System (UACS) is communication technology vastly used by the maritime domain until recently started to be explored for data communication purposes with the underwater medium. That is encouraged by usage of radio waves in water surface area is heavily attenuated by various factors, thus underwater medium made to be a potential alternative. However, the security factor must be taken as an essential consideration. There are many methods for building a communication security system (including underwater), such as encryption, user, and content authentification, which require a robust secret key.
In this final project, we will implement RSS based algorithm for the secret key generation in simple UACS, with choosing specific RSS value for communication between two parties only, which must be different with another link’s RSS value. The study for this final project covers underwater propagation link planning, implementation of simple UACS in ITS Hydrodynamics pool, and simulation of secret key generation. Next analysis and study of UACS performance will be conducted.
From the results of signal measurement and processing, with various algorithm schemes, it can be concluded that the Tone signal type has the smallest Bit Mismatch Rate value, while the Noise signal type has the largest Bit Mismatch Rate level.
