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.
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)
