Research and Design of Embedded Trusted Computing in Domestic IE-DCS

In order to solve the problems of complicated space environment, lack of built-in information security mechanism and limited chip resources faced by the domestic 1E-DCS, an embedded trusted computing design method applicable to the domestic 1E-DCS is researched and proposed. The methodology integrates the deterministic design requirements in functional safety, realizes the cyclic metrics on the static data of the startup process and the critical program and application data in operation, and finally forms a set of safety protection mechanism for the whole life cycle of 1E-DCS. Experimental results show that the mechanism design only increases the real-time response time of 1E-DCS by 0.91 ms, which is in line with the system response time requirements, and improves the overall ability of the domestic 1E-DCS to prevent known and unknown malicious attacks.
