Critical explores security in Embedded Systems as “built in” rather than as “add-on” functionalities
07/17/2011

Critical Software participates in international consortia that is running a pilot project focused on the creation of an embedded Systems arcHItecturE for multi-Layer Dependable solutions (in short pSHIELD). The aim of the project is to define a framework to improve the level of security associated to Embedded Systems while reducing the design and development costs. At the same time, the project will contribute to dramatically reduce the development cycles because the qualification, (re-)certification and (re-)validation process will be faster, easier and widely accepted.

Online PR News – 17-July-2011 – – The era where Embedded Systems were closed and inaccessible has ended. The exclusive (secure) physical access to Embedded Systems is no longer guaranteed; the present reveals a future where network connectivity is everywhere, leading to logical access methods, so common and as simple as using TCP/IP protocol to communicate.

In this new era, Embedded Systems are ever more prevalent, interoperability and information exchange is an increasing need and connectivity options proliferate in systems of this nature. This new context brings a whole new range of security issues that, if not managed properly, may pose serious safety and security risks. Without built-in security, the Embedded Systems, such as those used in automobiles, become extremely vulnerable to a wide spectrum of possible attackers with unpredictable consequences. The not so distant mass adoption of IPv6 and the endless amount of Embedded Systems that will surface with their own public IP address widens even more the number of possible targets.

The pSHIELD project addresses these issues building a framework that incorporates Security, Privacy and Dependability (SPD) concerns in the context of Embedded Systems as “built in” rather than as “add-on”. This framework is based on the design and development of open and dependable interfaces that allow both a static and dynamic composition of SPD technologies (e.g. cryptography, secure routing, semantic rules, and authentication), hence laying the foundations for becoming the reference for a new generation of “SPD-ready” Embedded Systems.

pSHIELD will approach SPD at 4 different levels: node, network, middleware and overlay. For each level, the state of the art in SPD of single technologies and solutions will be improved and integrated (e.g. hardware and communication technologies, cryptography, middleware, smart SPD applications). The framework will also use an overlay approach to SPD and introduce semantic technologies to address the complexity associated with the design, development and deployment of built-in SPD in Embedded Systems. Using semantics, the available technologies can be automatically composed to match the needed, application specific SPD levels, resulting in an effort reduction during the design, operational and maintaining phases.

The project will use an application scenario to validate the technology through monitoring of freight trains transporting hazardous material.

Critical Software’s experience in cryptography for low-powered and embedded systems aims to introduce the security paradigm from the very beginning (such as authentication mechanisms, secure communication channels, etc). The Critical Software responsibilities in the consortia are focussed on:

1. Researching the state-of-the-art in the means of providing security in lightweight and networked embedded devices through an adequate cryptographic scheme;
2. Analysing relevant requirements especially those used in the application scenario;
3. Developing a framework through which asymmetric and/or symmetric cryptography, using an appropriate key management scheme, can provide security for the proposed architecture.
