There are many kinds of control networks which have been used in various nonIP network areas, such as BA (building automation), FA (factory automation) and PA (process automation). These do not incorporate reasonable security mechanisms as they have been mainly used for closed networks. Recently the security of control networks is becoming important because… (More)
USAGI project was founded to improve and develop Linux IPv6 stack. We also developed (IPv6) IPsec stack for Linux kernel 2.4 and 2.6 series. We present our (IPv6) IPsec implementation (PE KEY, IPsec security association, security policy, output processing, and input processing) for both 2.4 and 2.6.
Due to the deployment of the Internet throughout the world, the IPv4 addresses, which are supporting the Internet, are predicted to run out around 2011. The industrial world has been preparing to the transition to IPv6. Recently, IP is being introduced to the fieldbus protocols, which is used in the industrial network. Due to its enormous amount of… (More)
SUMMARY There are many kinds of control networks, which have been used in various non-IP network areas, such as BA (Building Automation), FA (Factory Automation) and PA (Process Automation). They are now introducing IP and face the issues of security and configuration complexity. The authors have proposed a model which intends to solve these issues while… (More)
There are many kinds of control systems, which have been used in industry area, such as process automation (PA) and factory automation (FA). They have numerous sensors and actuators called field devices in their networks, and are introducing Internet protocol (IP) as network technology. Network security is necessary to make the most of IP's capability. The… (More)
