Secure RPC in embedded systems: evaluation of some GlobalPlatform implementation alternatives

In secure computing systems, isolation between different components is normally the basis for security. However, absolute isolation is seldom desired nor practical. Often for the system to function, a secure communication channel between otherwise isolated components is also needed. In this work, we will consider implementation of the secure Remote Procedure Call (RPC) mechanism defined by the GlobalPlatform specification on top of some different isolation mechanisms. Furthermore, implementation details, performance and security will be discussed.
