Embodiment approach

[0191] According to one embodiment, the device 90 further includes a key negotiation module configured to perform key negotiation with the trusted certificate generator to establish a trusted channel before sending the first authentication request to the trusted certificate generator, The trusted channel is used to send the first certificate request and receive the first certificate report.

[0192] According to another embodiment, an apparatus for distributing certificates for trusted computing units is provided, which is deployed in a trusted certificate generator. The trusted certificate generator can be implemented by any device, platform or device cluster with computing and processing capabilities. Figure 10 A schematic block diagram showing an apparatus for distributing certificates for trusted computing units in one embodiment. Such as Figure 10 As shown, the device 100 includes:

[0193] The first request receiving module 101 is configured to receive a first certi...

Abstract

The embodiment of the invention provides a method and device for providing a high-availability service by signing and issuing a certificate. According to the scheme, a trusted certificate generator distinguishes different calculation tasks through code hash, a certificate chain and a private key are generated for one code hash, the certificate chain comprises a public key certificate and a corresponding root certificate, and the public key certificate is matched with the private key to form a certificate pair. And then, the trusted certificate generator distributes the certificate pair to eachauthenticated trusted computing unit which runs the computing task corresponding to the code hash. And on the other hand, the trusted certificate generator distributes the root certificate in the certificate chain to the user terminal requesting the computing task. Thus, a user terminal having a root certificate and a trusted computing unit having a corresponding certificate pair can communicatesecurely by means of a TLS protocol.

Description

technical field [0001] One or more embodiments of this specification relate to the field of distributed computing and secure computing, and in particular to a method and an apparatus for providing highly available computing services in a distributed system. Background technique [0002] For the security of computing and data transmission, trusted computing units in Trusted Execution Environment (TEE) are often used for trusted computing and data processing, in which trusted computing units can ensure that the code execution is safe, and the outside world includes Neither the operating system nor the driver can obtain secrets such as internal runtime memory. For example, trusted computing units can be used to run applications and perform computing tasks, so as to ensure safe execution of program codes and isolation from the outside world. [0003] Due to the security needs of the trusted execution environment, before the user terminal and the trusted computing unit exchange ...
