Massive automation systems not possible with current technologies

Not enough many engineers on the globe to do the job with current technology

Arrowhead automation service framework based on Internet of Things and Service Oriented Architecture

enabling Collaborative automation involving almost any device and Machine supported system integration

Benefits to the production industry• Better optimization and coordination of single processes or process chains and of

complete plants and sites, • Significantly improved resource efficiency. • Better coordinated control loops in one process step and improved collaboration of

control systems of different processes along a process chain give higher process yields which results in better material efficiency, waste reduction, less energy use and reduction of pollution.

• Improved product quality through better process control and smart quality control• Higher utilization of equipment• New collaborative solutions with integrated information management offer new

possibilities for supply chain management including price-based coordination or optimised market mechanisms

• Safer operation of plants due to improved control and shut-down procedures. • Possibilities to integrate multiple processes.

Figure 6: Authentication process

4.1 Authentication Method

On the authentication process the server must recognize the user as a valid user andcommunicate that to the CoAP-NAS. This process needs to be flexible and compatiblewith other standards and with this goal the propose framework creates a public loginCoAP service on the CoAP-NAS. This login service must receive a PUT request withone of the following contents as a payload:

• User name and password as plain text. This option is only recommended duringtesting, debugging and development phases.

• User name and password hash. This is easy to implement and could be authenti-cated directly on the CoAP server (without RADIUS).

• A RADIUS packet (future work).

The possibility to run RADIUS protocol over CoAP (see section 2.4) gives to theframework a flexible authentication method usable with a standard RADIUS server.
