Security and real-time communication becomes more and more important for the widely application of industrial wireless technology in industrial system. However, it is difficult to guarantee both security and the real-time performance at same time in deterministic industrial wireless networks. Through the analysis of industrial wireless network requirements, a novel security mechanism in chip is proposed...
Wireless sensor networks extend people's ability to explore, monitor, and control the physical world. Wireless sensor networks are susceptible to certain types of attacks because they are deployed in open and unprotected environments. Novel intrusion tolerance architecture is proposed in this paper. An expert intrusion detection analysis system and an all-channel analyzer are introduced. A proposed...
Security plays an especially important role for application of wireless sensor network due to the vulnerability of network. In this paper, we propose and implement one approach of mutual authentication scheme with key agreement for wireless sensor network, which is significant to security provisioning in wireless sensor network with resource limitations. Then we discuss new sensor node security join...
Detecting intrusion attacks accurately and rapidly in wireless networks is one of the most challenging security problems. Intrusion attacks of various types can be detected by the change in traffic flow that they induce. Wireless industrial networks based on the wireless networks for industrial automation-process automation (WIA-PA) standard use a superframe to schedule network communications. We...
Industrial Wireless communications is emerging technology after the Fieldbus in industrial field. For industrial control application with wireless industrial technologies, the WIA-PA standard defines the protocol suite, system management, gateway, and security for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting the limited power consumption requirements. In...
The deployment of wireless technologies for device communication in the industrial control field is a challenging and promising issue mainly due to the increasing flexibility and the mobility. However, with limited resources such as computation capability and memory, traditional security solutions can not guarantee security requirements and communications overhead in industrial wireless networks....
