Abstract

LoRa (Long Range) termasuk pada konektivitas IoT nirkabel terbaru yang sedang berevolusi dan mendapatkanpopularitas dalam sistem tertanam dengan dioperasikan menggunakan daya rendah. LoRa perlu mentransfersejumlah kecil data pada interval pendek dengan jarak yang jauh. Modul komunikasi LoRa menggunakangelombang radio untuk melakukan komunikasi. Perangkat LoRa dihubungkan dengan frekuensi yang sama. Selainitu, dikarenakan LoRa menggunakan frekuensi sebagai metode komunikasinya, maka LoRa memiliki fitur yaitubroadcast. Pada fitur ini, LoRa mentransfer data pada frekuensi yang sama. Sehingga hal tersebut menjadi sebuahmasalah apabila terdapat perangkat LoRa yang melakukan transfer data penting, dikarenakan pada dasarnya LoRasendiri tidak memiliki upaya keamanan. Solusi berdasarkan permasalahan tersebut adalah diberikannya sebuahupaya keamanan yaitu berupa enkripsi pada data atau pesan yang dikirimkan. Pada penelitian yang dilakukan olehSemiconductor 2018 telah menerapkan algoritme AES-128 pada perangkat LoRa Namun terdapat penelitian lainyang menguji keefektifan algoritme AES-128bit dan menemukan beberapa kekurangan. Sehingga, pada penelitianini diterapkan algoritme SPECK 128/128bit yang memiliki kelebihan sehingga dapat menutupi kekurangan darialgoritme sebelumnya untuk mengamankan pesan penting yang dikirimkan agar tidak mudah dibaca oleh pihakyang tidak sah. Untuk menguji kemananan, serangkaian serangan aktif dan pasif dilakukan yaitu dengan metodeknown-plaintext attack. Hasil dari penelitian ini, sistem mampu memberikan keamanan pada pesan yangdikirimkan dengan mengirimkan pesan dalam bentuk ciphertext sehingga keamanan komunikasi antar modul LoRamenjadi terjamin.

Abstract

Long Range (LoRa) merupakan teknologi Low Power Wide Arean Network (LPWAN) yang digunakanuntuk transmisi menggunakan spectrum gelombang radio dengan transmisi jangkauan jarak yang jauhdan konsumsi daya yang rendah. Data yang ditransmisikan belum memiliki keamanan sehinggaintegritasnya tidak terjamin. Metode yang telah digunakan untuk keamanan integritas data yaitualgoritme SHA-256 yang sudah tidak aman untuk digunakan karena serangan collison attack dan secondpreimage. Oleh karena itu, algoritme BLAKE2S digunakan sebagai alternatif untuk menjaga integritasdata yang ditransmisikan. BLAKE2S telah terbukti sebagai algoritme yang memiliki tingat keamananyang lebih baik. Dari penelitian yang dihasilkan, algoritme BLAKE2S berhasil melakukan keamananyang diimplementasikan untuk menjamin keamanan data pada LoRa. Pengamanan data dilakukandengan mengubah menjadi message digest melalui proses hashing. Keamanan data dengan pengujianserangan aktif menggunakan teknik Man In The Middle Attack berhasil dilakukan. Ketika attackermelakukan serangan, gateway mampu melakukan pengecekan terhadap data dari node asli dan attackeryang dicocokan dengan data dari gateway sehingga menghasilkan data yang tidak valid yang berartiintegritas datanya terjamin.

Abstract

Long-Range (LoRa) merupakan teknologi Low Power Wide Area Network (LPWN) yang menggunakanmodulasi Chirp Spread Spectrum (CSS) yang berasal dari skema modulasi spread spectrum yang mampumempertahankan daya rendah serta meningkatkan jangkauan komunikasi yang dibutuhkan pada Internetof things (IoT). Perangkat LoRa melakukan komunikasi melalui radio gelombang dengan frekuensi yangsama. Pada penelitian ini LoRa berperan sebagai node dan gateway yang melakukan pengiriman datapada LoRa melalui broadcast dengan frekuensi yang sama. LoRa memiliki kelemahan pada keamanandatanya, di mana data yang dikirimkan ke node gateway masih rentan terhadap serangan pihak ketiga.Keamanan pada LoRa dapat ditingkatkan dengan menambahkan algoritme Grain-128a pada node dangateway yang bertujuan untuk memberikan keamanan pada data yang dikirimkan oleh node ke gateway.Grain-128a merupakan algoritme enkripsi yang menawarkan autentikasi opsional, yaitu melakukanenkripsi dengan autentikasi dan tanpa autentikasi pada data. Pada penelitian ini Grain-128a berhasilmelakukan pengamanan pada data suhu dan pada modul komunikasi LoRa berdasarkan dari pengujianyang telah dilakukan. Pada pengujian known-plaintext attack yang dilakukan, penyerang tidak berhasilmengetahui plaintext dari ciphertext yang dihasilkan algoritme Grain-128a. Hal ini membuktikan bahwapenyerang tidak berhasil melakukan penyerangan, dan algoritme Grain-128a berhasil melakukanpengamanan pada data.

Abstract

This study discusses the acceptance of Windows 10 as operating system for desktop. This study is based on the seven constructs of the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) from Venkatesh et al. (2012) without moderate constructs who processed with Structural Equation Model (SEM). The respondents were teenage users in Indonesia. The result showed that effort expectancy, facilitating condition and price value do not have a significant positive impact on behavioral intentions while performance expectancy, social influence, hedonic motivation and habit had a significant positive effect on behavior intention. On the other hand, facilitating condition and habit factors influence use behavior while behavior intention do not have a positive impact on use behaviour to use Windows 10.

Abstract

Garuda Training Cost is a web application for calculating the training costs for pilots and flight attendants developed in Garuda Indonesia Training Center. This application use SHA-1 hash function algorithm to secure user password in database. However, the weakness and colisions have been found in this algorithm, therefore this algorithm less secure. Hence, in this research authors will replace the SHA-1 with the algorithm successor, SHA-3. This algorithm will be implemented in login process, password change process and adding users process. Both algorithm will be tested and analyzed to determine the performance of the algorithm. There are three types of tests performed. The first is brute-force testing, second is avalanche effect testing and the final test is processing time testing. From the brute-force test result, SHA-3 algorithm much better than SHA-1. From the 30 times testing for 10-character password, the SHA-1 generated hash need average 14 hours 53 minutes and 51 seconds to find the plaintext. While SHA-3 generated hash need average 4 days 13 hours 6 minutes and 6 seconds to find the plaintext. For the avalanche effect testing, SHA-1 algorithm get a percentage change of 100%, while SHA-3 get 95%. For the processing time testing, SHA-1 algorithm is better because of SHA-3 higher complexity. Although two of three test SHA-1 is better, does not mean SHA-3 is not better. Minimum avalanche effect percentage for an algorithm is 50%. And that processing time is still in milliseconds unit, so that user do not feel the impact directly. In conclusion, the three these tests show that the SHA-3 has a higher resistance than the algorithm SHA-1.
