Current cryptographic techniques pose high computational
requirements on the executing system. Particularly in
embedded systems, where limited resources regarding computational
power, energy, and cost are a common case, this can lead
to difficulties when establishing the required security properties.
Our approach tackles the problem of limited recources by
introducing a crypto-enabled memory which is a special purpose
hardware forming a new basic building block in System-on-Chip
(SoC) design. It bundles a cryptographic function and a memory
block in an atomic unit that can be instantiated multiple times
in a single SoC. Compared to pure software implementations,
the proposed hardware accelerated extensions have improved
performance and energy efficiency. Moreover, the crypto-enabled
memory is totally transparent to the application and hence
enables the seamless integration of security mechanisms into
a system. To show the feasibility of our approach we have
implemented a middleware module in hardware that realizes
end-to-end encryption between distributed processor cores in
the Time-Triggered SoC (TTSoC) Architecture, which is a novel
integrated architecture for embedded systems.
