Recently, USN (ubiquitous sensor network) technologies have been widely applied to various kinds of systems in society at large. In this paper, we identify security vulnerabilities in the systems using USN-based technologies and propose a security structure to securely protect the systems from malicious attacks. Most of the systems based on the USN technologies check a transmission error of the collected data by default during collecting and transmitting data in real time. However, these systems operate systematically without regard to security section. Therefore, these systems lack of the way to prevent and identify the data forgery and modulation when the data is transmitted and processed. The proposed scheme uses a public-key method to compensate for the security vulnerabilities in USN systems. By applying the secure structure to the automatic plant growth measurement system which is using one of USN-based technologies, we have checked whether the data is securely transmitted and processed or not on the system. The proposed method has been verified through safety analysis about the essential security requirements (confidentiality, authentication and integrity) of the threats (node authentication information disclosure, message content forgery and exposure) that may occur as typical type of attacks (node takeover, data forgery and eavesdropping) on USN systems. |
