The invention discloses a heterogeneous fusion method, device, computer equipment and storage medium of a trusted computing environment, which are applied to the field of computer security and are used to solve the problem that TEE applications in a heterogeneous trusted computing environment cannot directly communicate with each other. The present invention determines that the TEE container itself is credible by initializing the TEE container. Obtain the client public key and the server public key by negotiating the communication key request. The server decrypts and verifies the client's local integrity measurement report through the obtained client public key, and determines that the client is a trusted TEE application of the server; the client decrypts and verifies the server's local integrity measurement report through the obtained server public key, and determines that the server is a trusted TEE application. The client-side trusted TEE application opens a trusted closed loop and establishes mutual trust. Finally, the client encrypts and sends a trusted call request, and the server receives the request, decrypts it, processes the returned call result, and implements trusted mutual calls.
Description
technical field [0001] The invention relates to the field of computer security, in particular to a heterogeneous fusion method, device, computer equipment and storage medium of a trusted computing environment. Background technique [0002] Trusted Computing Environment TEE (Trusted Execution Environment) is a concept proposed by GlobalPlatform, a global platform organization. By isolating an operating space in the central processing unit from the operating system, under the condition that the native operating system and peripherals are not secure, it can still It can protect programs and data running in TEE. [0003] In practical applications, currently popular solutions include TrustZone for ARM (Advanced RISC Machine) architecture processors and SGX (SoftwareGuard Extensions) for x86 (The X86 architecture) architecture processors. [0004] ARM (Advanced RISC Machine) trust zone is a security technology launched by ARM that aims to enforce security on hardware, and has bee...
