92 Internet of Things Strategic Research and Innovation Agenda
• Detection-oriented CEP: Focused on detecting combinations of
events called event patterns or situations. A simple example of
detecting a situation is to look for a specific sequence of events.
Some of the research topics for the immediate future in the context of CEP are:
• Distributed CEP: Since CEP core engines usually require powerful
hardware and complex input data to consider, it is not easy to
design and implement distributed systems capable of taking consistent
decisions from non-centralised resources.
• Definition of standardised interfaces: Currently, most of the CEP
solutions are totally proprietary and not compliant with any type of
standard format or interface. In addition, it is not easy to integrate
these processes in other systems in an automated way. It is essential
to standardise input and output interfaces in order to make CEP systems
interoperable among themselves (thus enabling exchanging
of input events and results) and to ease integration of CEP in other
systems, just as any other step in the transformation or processing
of data.
• Improved security and privacy policies: CEP systems often
imply the handling of “private” data that are incorporated to decision
taking or elaboration of more complex data. It is necessary
that all processes and synthetic data can be limited by well-defined
rules and security constraints (that must be measurable, traceable
and verifiable).
2.9 Security, Privacy & Trust
The Internet of Things presents security-related challenges that are identified
in the IERC 2010 Strategic Research and Innovation Roadmap but some
elaboration is useful as there are further aspects that need to be addressed
by the research community. While there are a number of specific security,
privacy and trust challenges in the IoT, they all share a number of transverse
non-functional requirements:
• Lightweight and symmetric solutions, Support for resource constrained
devices
• Scalable to billions of devices/transactions
