Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 90h |
| 1 | Subcommand, subcommand=82h |
| 2 | Action selector, which indicates the current command action. The options are as follows: 00h: set 01h: query |
| 3 | Direction: indicates the operation direction of the current command file. The options are as follows: 00h: export 01h: import |
| 4 | File Type: type of the file operated by the current command. The options are as follows: 00h: asymmetric public key for encrypting the security chip firmware (export only) 01h: encryption key of the security chip firmware (The key can be imported only and cannot be imported again after being imported.) |
| 5:6 | Reserved. Set to 0. |
| 7:N | Datas. The value varies according to the value of Action Selector. For details, see Table 1. |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion code. The value varies according to the value of Action Selector. For details, see Table 1. |
| 2:N | Datas. The value varies according to the value of Action Selector. For details, see Table 1. |

| Action Selector | # | Request Datas | Response Datas |
|---|---|---|---|
| Setting | 00h | Byte[7]: file name length (N) Byte[8:7+N]: file name (with the path) Byte[8+N]: length (M) of the extended information. The value varies according to the value of File Type. When File Type is set to 00h, the value is fixed to 1.When the value of File Type is 01h, the value is the digest value of the encryption key of the security chip firmware. Byte[9+N:8+M+N]: extended information. The options are as follows based on the value of File Type: When File Type is set to 00h, this parameter indicates the asymmetric public key algorithm. The options are as follows: 00h: RSA2048; 01h: RSA409601h: encryption key digest value of the security chip firmware | Byte[1]: CompletionCode. When the operation is to import the encryption key of the security chip firmware, the following response is returned: 85h: The encryption key format of the security chip firmware is incorrect. 86h: The encryption key of the security chip firmware is incorrectly processed. 87h: The encryption key of the security chip firmware already exists. Byte[2:N]: N/A |
| Query | 01h | This part does not exist. | Byte[1]: CompletionCode Byte[2]: task status. The value can be any of the following: 00h: The operation is complete.01h: The operation fails.02h: The operation is being performed.FFh: idle state, not started Byte[3]: operation progress percentage. The value ranges from 0 to 100. |
Command Example
Export the asymmetric public key "/tmp/test.pub" for encrypting the firmware of the security chip.
