Preparing the Environment

The verify lib, QCA lib, and QTA are open-sourced in the openEuler community. You can see the demos to learn how to use remote attestation APIs and develop remote attestation applications.

The sections that follow demonstrate remote attestation on a server. You can open four windows to simulate the modules involved in remote attestation.

• Window 1: indicates the Attestation Service. If the NO AS mode is used, do not open this window.
• Window 2: indicates the RA Service, which receives remote attestation requests. The QCA lib and QTA are contained in the RA Service.
• Window 3: indicates the target TA, which runs on the RA Server.
• Window 4: indicates the RA Client, which initiates remote attestation requests. The verify lib is deployed on the RA Client.
