Current User Information
- In this text box, you can view the public and private keys of the current user. If other users want to use their public and private keys to log in to the node administrator interface, they can copy their public and private keys to this text box.
- After copying your public and private keys, click Import the public key to add the public key to the local node administrator
- The first five public keys are displayed in Local public key. If you select your own public key, the role of the selected public key will be displayed in My permission. If the node has not been authenticated by the central administrator, the default value is Anonymous.
- If you are not a node administrator and want to join the network of a central administrator, use your own public and private keys to import the key to the user management where the central administrator resides for authentication.
- If you want to perform more operations on contracts, you need to authenticate different roles: contract administrator, contract consumer, contract provider, and then Role of certification
List of authorized and unauthorized users
After the node administrator authenticates the role, the node administrator will see the application information with the public key in the Role management is not authorized form. If yes, click . If no, click . After authorization, you will see a list of authorized nodes in the Authorized Role Management table. If the node administrator wants to remove a role from a node, enter delete in the entitlement role management list.
