Configuring the KMC Encryption Algorithm

You can configure the KMC encryption algorithm based on service requirements. If you do not configure it, the default configuration is used.

Configuring an Encryption Algorithm for MEF Center

Log in to the MEF Center device environment as the root user.
Go to the path of the MEF Center configuration file. The default installation directory is /usr/local.
```
cd Installation_path/MEF-Center/mef-config/public-config
```

Edit the algorithms field in the kmc-config.json file. The default encryption algorithm is AES_GCM_256.

{
    "algorithms":"Aes256gcm"
}

**Table 1** Description of the algorithms field
Value	Description
Aes256gcm	Default value, indicating that the AES_GCM_256 encryption algorithm is used.
Aes128gcm	Indicates that the AES_GCM_128 encryption algorithm is used.

Restart MEF Center for the configuration to take effect. For details, see Restarting MEF Center.

Configuring an Encryption Algorithm for MEF Edge

Go to the MEF Edge configuration file path and modify the configuration files of edge_om and edge_main. The default installation directory is /usr/local/mindx.

Go to the directory where the edge_om configuration file is stored.
```
cd Installation_path/MEFEdge/config/edge_om
```
Edit the algorithms field in the kmc-config.json file. The default encryption algorithm is AES_GCM_256.
```
{
    "algorithms":"Aes256gcm"
}
```

Go to the directory where the edge_main configuration file is stored.

cd Installation_path/MEFEdge/config/edge_main

Edit the algorithms field in the kmc-config.json file. The default encryption algorithm is AES_GCM_256.

{
    "algorithms":"Aes256gcm"
}

**Table 2** Description of the algorithms field
Value	Description
Aes256gcm	Default value, indicating that the AES_GCM_256 encryption algorithm is used.
Aes128gcm	Indicates that the AES_GCM_128 encryption algorithm is used.

Restart MEF Edge for the configuration to take effect. For details, see Restarting MEF Edge.
