Creating key, data, and project

Available in VPC

Once you've completed requesting subscription, you can use the console to create encryption keys, upload data, and create projects.

Homomorphic encryption keys are used for encryption and decryption of uploaded data and for computation of encrypted data. Projects are used as workspaces to perform computations using the key files and data that are prepared.

Create and manage encryption keys

You can create a key for encryption on the console, or create an encryption key file locally and upload it. Data can be uploaded once you have the key ready.

Create key on the console

The following describes how to create a new encryption key on the console.

1. From the VPC environment of the NAVER Cloud Platform console, click the Services > Big Data & Analytics > HEaaN Homomorphic Analytics > Key menus, in that order.
2. Click the [Create key] button.
3. Enter the name and description for the key.
4. Select the key's Capability by referring to the table below, and then click the [Confirm] button.
   • Encryption block size: Number of rows or columns contained in one ciphertext (Refer to Encryption method)

5. From the confirmation pop-up window, click the [Confirm] button.

Create key locally and upload

You can use an agent to create an encryption key locally and upload to the cloud. The following OSes support agents.

• Linux - RHEL/CentOS
• Linux - Ubuntu
• Mac OS

The following describes how to create a key file locally and upload it using the agent.

1. Refer to Using agent and create an encryption key file locally.
2. From the VPC environment of the NAVER Cloud Platform console, click the Services > Big Data & Analytics > HEaaN Homomorphic Analytics > Key menus, in that order.
3. Click the [Upload key] button.
4. Enter the name of the key to upload.
   • Entering the key name will automatically complete an agent command with the key name reflected, and you can click the [Copy] button to copy the command to the clipboard.
5. Click the [OK] button.
6. Paste the copied command in the terminal environment to run the agent, and then enter commands according to the key creation path and capability.
   • Creating and uploading the key will be done automatically.

View key list

The key files created are shown in the key list on the console. You can perform management tasks in the list, such as viewing, downloading, or deleting the keys.

To see the list of key files, click the Services > Big Data & Analytics > HEaaN Homomorphic Analytics > Key menus, in that order, from the VPC environment of the NAVER Cloud Platform console.

View key details

2. Click the [Delete key] button above the key list.
3. Enter the key's name in the confirmation pop-up window, and then click the [Delete] button.

Upload and manage data

You can use the HEaaN Homomorphic Analytics to upload data to be used for computations.

You can encrypt the uploaded data on the cloud using the homomorphic encryption key created in advance, or complete encryption locally and upload it to the cloud. You can use the uploaded and encrypted data to create projects or tasks, as well as perform computations.

Create folder

Create a folder first to upload data. You can skip this stage if you upload the data to the folder created in advance.

1. From the VPC environment of the NAVER Cloud Platform console, click the Services > Big Data & Analytics > HEaaN Homomorphic Analytics > Data menus, in that order.
2. Click the [Create data folder] button.
3. Enter the Folder name and click the [OK] button.

Upload to cloud and encrypt

Once you've created a homomorphic encryption key file, you can upload data to the cloud. Select a key file and upload data. The encryption will take place on the cloud.

The following describes how to upload computation data to encrypt on the cloud.

1. From the VPC environment of the NAVER Cloud Platform console, click the Services > Big Data & Analytics > HEaaN Homomorphic Analytics > Data menus, in that order.
2. Select the folder to upload.
3. Click the [Upload data] button.
