With the rapid expansion of the human-centric ubiquitous environment, wireless sensor networks (WSN) will continue to be part of our everyday life and increase the amount and the type of data generated and transmitted by the WSN. As sensors become more essential in our daily life, the data from the sensors will become more private and need to be handled more sensitively. Therefore, the security of not only the data transmission between sensor nodes, but also the software system handling the data from sensor nodes will become more important. In this study, I concentrated on the security characteristics of the overall application systems in WSNs and derived the security attributes from the security requirements and standards of the existing network-based software systems. In the software development process, security must be considered throughout the whole process and, according to the applications the priority of each security attribute can be changed. I demonstrated the relative priority change in a web-based system and a WSN application system with an Analytic Hierarchy Process. The evaluation results showed that the difference of the relative priority of the security attributes in each sample system results not from the difference between the existing network-based system and the WSN but the type of the application. Therefore, the Multimedia security requirements and standards of the existing network-based software development process can be applied to the WSN application system through proper selection and modification.

Ad hoc networks are autonomously distributed wireless networks which consist of wireless terminals (hereinafter, referred to as nodes). They do not rely on wireless network infrastructures such as base stations. Relaying nodes and their surrounding nodes are susceptible to data theft and eavesdropping because nodes communicate via radio waves. Previously, we had proposed the secure dispersed data transfer method for encryption, decryption, and transfer of the original data packets. To use the secure dispersed data transfer method securely, we had proposed using the node-disjoint multipath routing method. In this method, multiple versions of encrypted data packets are transferred along each disjoint multipath to counter data packet theft. We had also proposed the enhanced version of the aforementioned routing method to reduce radio area overlap by using rebroadcasting of control packets to counter eavesdropping attacks. In this paper, we propose a multipath routing method to reduce radio area overlap through the introduction of control packet overhearing. We introduce control packet overhearing mechanisms to eliminate excess control packet counts and latency in the pathfinding process. Our main contributions are as follows: (1) our proposed method can reduce radio area overlap without each node's geographical location information (e.g., using GPS information); (2) our proposed method also can eliminate excess control packets and latency without degradation of the security. Furthermore we conducted simulation experiments to evaluate our proposed method. We observed that our proposed method can construct the desired paths with a smaller amount of control packets and a shorter latency in the pathfinding process. We also conducted additional experiments to discuss the applicable scope of our proposed method. As a result, we confirmed that our proposed method was more effective as the average number of adjacent nodes increased.

“…Instead of single path, the data are routed through two or more paths, and therefore the multipath mechanism is considered to be more fault tolerant than the conventional single path approach (Alrajeh et al, 2013a). Multipath routing protects data security in WSNs against attacks by reducing the chance of a packet being modified or dropped by a malicious sensor node (Kohno et al, 2012). Moreover, lightweight security mechanism can be adapted to the multipath routing technique to further enhance the security of transmission by mitigating the impact of network attacks in WSNs (Khalil et al, 2010).…”
