Creating a CA, TA or RSA Project

Prerequisites

• You have logged in to the Kunpeng DevKit.
• The Development Assistant has been installed. You are advised to install the Compiler and Debugger and add a target server before creating a project for future compilation and debugging.

Procedure

1. Click in the shortcut menu bar on the left pane or click next to Development Assistant. The Kunpeng Application Projects page is displayed. See Figure 1.
   Figure 1 Kunpeng Application Projects
   
2. Click Secure Computing Application. The Secure Computing Application page is displayed. See Figure 2.
   Figure 2 Secure Computing Application
   
3. Click GlobalPlatform-Compliant TEE Application. On the left pane of the displayed page, select CA project, TA project, or RSA project for Project Type and set other parameters as required. See Figure 3.

   Table 1 Parameter settings (1)

   Parameter	Description
   Project Type	The options are: Template project CA Project TA Project RSA Project Data Sealing Secret Vote Cert Assign Empty project NOTE: A CA project runs in the REE, and a TA project runs in the TEE. An RSA project implements secure communication based on the CA and TA projects. A data sealing project includes CA and TA projects. The TEE secure storage interface is used to store confidential data. A secret voting project includes CA and TA projects and is based on Advanced Encryption Standard (AES) and RSA encryption. A certificate assignment project includes CA and TA projects. Certificates are issued based on the RSA and SM2 algorithms. Dependencies: Ensure that kunpeng-sc has been installed. (For data sealing and secret voting projects, ensure that kunpeng-sc-devel has been installed. For certificate assignment projects, ensure that the confidential computing SDK and kunpeng-sc-devel have been installed.) Run the lsmod | grep tzdriver command to check that the tzdriver is properly loaded. Run the ps -ef| grep teecd command to check that the daemon is properly started.
   Project Name	Name of the project to be created. The default project name is xxx_ProjectN, which can be modified as required. NOTE: N is an integer starting from 1 in ascending order. The project name can contain 1 to 64 characters, including only letters, digits, periods (.), hyphens (-), plus signs (+), parentheses (), and underscores (_). It cannot start with a period (.).
   Project Location	Storage path of the project to be created. The default project location is C:\Users\username\KunpengProject, which can be modified as required.
   (Optional) Signature Private Key	Import the signature private key file.
   (Optional) Config Binary	Import the binary configuration file.

   

   CA project creation does not involve the Signature Private Key and Config Binary configuration items.

4. Click Next to configure the target node. You can use an existing server or add a new server. To add a server, enter the IP address, SSH port, user name, password, and storage directory. If you select Configure later, no SDKs will be deployed by default. See Figure 4.
   Figure 4 Configuring the target node
   

   Table 2 Parameter settings (2)

   Parameter	Description
   Deploy Server	Existing New Configure later NOTE: The new server will be added to the target server management.
   IP Address	IP address of the target node for subsequent operations.
   SSH Port	SSH port number of the target node.
   User Name	Account of the target node for subsequent operations.
   Password	Password of the target node user.
   Remember password	If you select this option, the password of the current server user will be remembered.
   Storage Directory	Storage directory on the target node. NOTE: The tool reads and writes the content in the storage directory. To avoid data loss, you are advised to use an empty directory.
   Deploy SDK When Creating Project	Yes: deploys the SDK. No: does not deploy the SDK.
   Deploy SDK	Select an SDK deployment method. Online deployment kunpeng-sc kunpeng-sc-devel Offline deployment kunpeng-sc kunpeng-sc-devel NOTE: If you select Online deployment, the server must be connected to the Internet. In an isolated network environment, you need to use a proxy to access the Internet. For details, see Configuring a Proxy. If you select Offline deployment, the SDK is imported from the local host. Download the SDK to the local host and upload it.

   

   When configuring the new target node, ensure that the node is running on a physical machine and runs the openEuler 20.03 LTS SP1, UOS 20 SP1, CentOS 7.6, or Kylin V10 in the Arm architecture, and that you have administrator permissions for the node.

5. Determine whether to deploy the SDK when creating the project. If you select Yes, specify a deployment method. See Figure 5. Click Create.
   Figure 5 Deploying the SDK
   
   

   If the secure computing SDK fails to be deployed, rectify the fault by following instructions in Failed to Deploy the Secure Computing Application SDK.

6. During project creation, the corresponding module content in the secure computing application framework will be verified. You can click Terminate Configuration on the verification page to stop the current verification. If the verification is successful, the module content on the right is displayed in green. If the verification fails, the content is displayed in red.

   Figure 7 Verification success
   
   Figure 8 Verification failure
   
   

   • If the parameters fail to be set, check the network connection and reconfigure the parameters.
   • If the verification fails in online SDK deployment mode, click Retry. If the verification fails in offline SDK deployment mode, click Retry, or click reselect and upload to upload the SDK and perform another verification.
7. After the RSA project is created, click Open Project to open it in the current window.

8. You can use the Compiler and Debugger tool to compile, run, and debug the new project. The specific operations are subject to the project type.
   • If you create a CA project, perform compilation and debugging directly.
   • If you create a TA project, use it together with the CA project. For details, see the README file in the TA project folder.
   • If you create an RSA project, use it together with the TA and CA projects. For details, see the README file in the RSA project folder. After the compilation is complete, copy the generated files to the specified directory by following instructions in Instructions on Running Secure Computing Applications.

   If a project folder or file is added, deleted, modified, or renamed, you can synchronize the change to the remote server. For details, see Synchronizing Code to a Remote Server.
