Building secure embedded kernels with the Think architecture
Christophe Rippert, Jean‐Bernard Stefani · 2002
We present in this paper the security features of Think, an object-oriented architecture dedicated to build customized operating system kernels. The Think architecture is composed of an object-oriented software framework including a trader, and a library of system abstractions programmed as components. We show how to use this architecture to build secure and efficient kernels for embedded systems. Policy neutral security is achieved by providing elementary tools that can be used by the system programmer to build a system resistant to denial of service attacks and incorporating data access control. An example of such a secure system is given by detailing how to ensure component isolation with a elementary software-based memory isolation tool.
