QingTian Enclave

What Is QingTian Enclave?

QingTian Enclave is an advanced security feature based on the Huawei Cloud QingTian architecture and allows you to create a secure, isolated execution environment. QingTian Enclave instances are completely separate VMs and have no persistent storage, interactive access, or external networking. They communicate with the parent instance through a secure local channel, which is called vsock. Even the root user of the parent instance cannot access or SSH into QingTian Enclave instances.

Application Scenarios

QingTian Enclave allows you to create isolated execution environments from ECS instances to secure your sensitive data, such as personal identity information, keys, healthcare data, financial data, and intellectual property data. In this way, you can ensure the data confidentiality and reduce the attack surface area during the processing of sensitive data.

Advantages

Superb Isolation and Security
QingTian Enclave instances are completely separate VMs and have no persistent storage, interactive access, or external networking. They communicate with the parent instance through a secure local channel, which is called vsock. Even the root user of the parent instance cannot access or SSH into QingTian Enclave instances.
Cryptographic Attestation
QingTian Enclave instances support cryptographic attestation. The instances use cryptographic attestation to prove their identities and build trust with external services. The attestation process uses an attestation document that includes the measurements of the QingTian Enclave runtime environment. These measurements can be used to create access control policies in external services to control access to specific operations for specific QingTian Enclave instances.
Flexibility
You can create QingTian Enclave instances with different combinations of vCPUs and memory. QingTian Enclave combines hardware and software. It is processor agnostic and compatible with any programming language or framework. In addition, since many components of QingTian Enclave are open sourced, you can even check and verify the code by yourself.

Multiple QingTian Enclaves Support
You can create multiple separate, isolated QingTian Enclave security zones on a parent instance for confidential computing.
