Methods for constructing trusted grid, trusted grids, and application interaction methods thereon

Abstract

Trusted grid construction includes respectively loading, by a plurality of computing nodes, uniform target code in trusted execution environments (TEEs) of the plurality of computing nodes. A target metric value corresponding to the target code is stored to form a plurality of trusted nodes, where target logic corresponding to the uniform target code includes trusted proxy logic configured to provide a security related service for an upper-layer application. Each trusted node performs mutual verification with another trusted node based on the target metric value. A secure connection is established to the another trusted node after the mutual verification is passed, where a plurality of trusted nodes that establish secure connections to each other form a trusted grid.
