Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] The heterogeneous fusion method of a trusted computing environment provided by this application can be applied in such as figure 1 An application environment in which a client communicates with a server over a network. Among them, clients and servers can be but not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices. The server can be implemented by an independent server or a s...

The invention discloses a heterogeneous fusion method and device for a trusted computing environment, computer equipment and a storage medium, is applied to the field of computer security, and is usedfor solving the problem that TEE applications of a heterogeneous trusted computing environment cannot directly communicate with each other. By initializing a TEE container, the credibility of the TEEcontainer is determined. A client public key and a server public key are obtained by negotiating a communication key request. A server decrypts and verifies a client local integrity measurement report through the obtained client public key, and determines that the client is a server trusted TEE application; and the client decrypts and verifies the local integrity measurement report of the serverthrough the obtained server public key, determines that the server is a trusted TEE application of the client, opens a trusted closed loop and establishes mutual trust. Finally, the client encrypts and sends a credible calling request, and the server receives the request, decrypts the request, processes and returns a calling result to realize credible mutual calling.
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...
