Secure Plug and Play Architecture for Field Devices

A PA (Process Automation) system is a kind of control systems which have been used in various non-IP (Internet Protocol) network areas. The system is now introducing IP with advantages, and will face the issues of security and configuration complexity due to upcoming new requirements. The authors have proposed a model called Secure Plug and Play which intends to solve these issues while satisfying restrictions, i.e. small embedded devices, isolated networks, private naming system/name space and application transparency, which are required when introducing new functionality into the existing systems. This paper shows the practicability of the model through implementing the model experimentally.
