TECOM · Trusted Embedded Computing

Trusted Computing (TC) has become meanwhile an established technology for verification and implementation of integrity and security at personal computers. Similar requirements are also needed for embedded computing platforms which have alike trust and security problems due to the increasing complexity and therefore instability of Os and applications as well as connection to the Internet with its security dangers and attacks. Until now the TC standard is mainly targeted for PCs with their large resources of available code space, specific bus interfaces and large computing power which are not available with embedded platforms.As there are a much higher number of embedded computing platforms like PCs in the field, it becomes a necessity to adapt the current TC standard to embedded platforms.The project will make an systematic approach for the development of trusted embedded systems, consisting of hardware platforms with integrated trust components and also work on the necessary trusted operating systems:1.Trusted hardware, Trusted Platform Module as VHDL design, which could adapted to different host systems together with processors supporting a trust architecture2.Trusted operating systems mainly based on the new virtualisation/hypervisor architecture which are already in use at the PC world. Adapting it to the specific requirements of small platforms and trusted modules3.Security layers for implementing easy accessible security mechanisms.4.Trusted protocols: Elementary TC protocols like TSS (Host interface API) and TNC (trusted network connect, an advanced secure communication protocol) will be adapted for embedded platforms5.Application examples will give us feedback about available trust functionality, application friendliness and user requirements.We will use the results and experience from the project to influence the TC standardisation and prepare for application scenarios like mobile phones, communication, e-commerce, industrial and automotive
