Abstract

The invention provides a method and a system for realizing secure and high-performance inter-process communication, and the method comprises the following steps: a developer completes Enclave development and loads the Enclave development to a computing system; a host process Host program is loaded by a computing system, and thus starting an enclave process Enclave; a host process Host program starts communication with an enclave process Enclave, and a Monitor is called to request inter-process communication; the Monitor ensures that the relay page only has one memory mapping, and the ownership of the Monitor is transferred from the host process Host to the enclave process Enclave; inter-process communication between an enclave process Enclave program and another enclave process Enclave is started, and the monitor establishes connection between an enclave process Enclave 1 and a Name Server; the enclave process Enclave 1 requests the Capability of the enclave process Enclave 2 from the Name Server; and the Monitor remaps the relay page to realize the message transmission between the enclave process Enclave 1 and the enclave process Enclave 2. According to the invention, a relay page and software and hardware collaboratively provide integrity protection, so that an enclave process is subjected to high-performance inter-process communication (IPC) in a trusted computing scene.

Description

Technical field[0001]The present invention relates to the field of trusted calculation, and in particular, to a method and system for realizing communication between processes and high performance processes.Background technique[0002]Trusted Calculation Technology: Trusted Computing, TC) is a technique that is promoted and developed by trustedcomputing group, called TCPA, called TCPA. This term comes from a trusted system (trusted system) and has its specific meaning. Specifically, it means that it is possible to fully comply with its behavior to comply with the design, and the probability of behavior prohibited by the execution designer and software writer is very low. System security and process interval in trusted computing computing are higher, resulting in high processes inter-process overhead.[0003]RISC-V: is an open source instruction set architecture (ISA) based on a thin instruction set (RISC) principle, which is easy to interpret "open source hardware" corresponding to the ...
