<p class="0abstract"><span lang="EN-US">In order to study the intelligent buildings, the intelligent building network security of wireless sensor was explored. Because of its advantages of low cost, easy installation, low maintenance and update cost, wireless sensor network system was applied to intelligent building. In view of the characteristics of various influencing factors on the wireless sensor network working environment, node hardware cost and location accuracy, a secure localization algorithm based on DV-Hop was put forward. The security analysis results showed that the algorithm resisted external attacks and guaranteed the accuracy of location results. Based on the above findings, it is concluded that the algorithm can be used to protect the safety of wireless sensor network in building. </span></p>

Industrial Wireless Sensor Network

Standar IEEE 802.15.4 merupakan standar acuan pengembangan protokol yang diterapkan untuk teknologi industrial wireless sensor network pada saat ini. Unsur keamanan data dalam industrial wireless sensor network perlu untuk diperhatikan karena dampak gangguan yang timbul akan dapat berpengaruh secara langsung pada proses industri yang sedang beroperasi dan berdampak pada keselamatan pekerja, peralatan dan lingkungan serta keekonomian. Metode enkripsi adalah metode umum yang dipergunakan dalam perlindungan data pada sistem wireless sensor network. Metode enkripsi pada layer physical dengan menggunakan algoritma stream cipher Rabbit dipergunakan sebagai metode alternatif perlindungan data pada sistem aplikasi industrial wireless sensor network yang mana pada umumnya menggunakan metode enkripsi block cipher pada lapisan upper layer. Algoritma Rabbit akan dibandingkan dengan algoritma RC4 yang telah diteliti sebelumnya. Dari hasil simulasi, algoritma Rabbit dengan jumlah kunci yang lebih pendek dan cipher text yang lebih sedikit dapat memberikan hasil yang lebih baik untuk nilai avalanche effect, entrophy dan penggunaan CPU dibandingkan dengan algoritma RC4. Meskipun mendapatkan hasil yang bervariasi pada penggunaan memori dan end to end delay, algoritma Rabbit pada jumlah node tertentu masih dapat memenuhi standar kebutuhan industri untuk aplikasi sektor migas.

A new and secure chaos-based block cipher for image encryption in wireless sensor networks is proposed. The security analysis and the performances of the proposed algorithm have been investigated. The statistical analysis includes the histograms and correlation coefficients of adjacent pixels. In the differential analysis, the authors use the Number of Pixels Change Rate (NPCR) and the Unified Changing Average (UACI) measures to demonstrate the security against differential attacks. Key sensitivity analysis and key space analysis show that the proposed cipher is secure and resistant to brute force attack. The authors demonstrate that the performance of the cipher exceeds the studied encryption algorithms as well as AES (Advanced Encryption Standard). An implementation on a real wireless sensor network testbed is realized, and the energy consumption is investigated.
