Abstract: The traditional embedded system networking technology ignores the security of network systems, either ignores fast networking requirements of network system, these requirements can be achieved at the same time. A embedded dynamic security networking technology based on fast jump and trust degree is proposed, when systems is networking, the use of random beating from multiple network nodes and fast switching optimize network search methods. Experimental results show that the proposed method can detect distribution of systems security risks accurately, and has a good application value for network security.

Abstract: The first long-term bridge monitoring system in Korea was installed in 1995, and many bridges have been maintained by long-term monitoring systems. Recently, reliability of data and cost effectiveness have been increased by advanced sensor technology (fiber optic sensor, RFID, USN etc) and measuring equipment. In Korea, the large-scale project for the safety network integration for long-term smart monitoring systems for bridge structures started in 2007, and this is the second year of the project. In this system, various innovative sensor types are considered. To increase the effectiveness of this network system, an analysis of the problems with the conventional long-term bridge monitoring system and solution investigations are needed. The biggest problems are low durability and data reliability because of noise, and the lack of data applications techniques. Therefore, in this paper, a brief summary of the projects is presented and the state of bridge monitoring systems in Korea is investigated, and various problems and solutions for these problems are briefly suggested.
