WISeNeT Mutual Authentication Guide for Devices

Hanwha Techwin devices are equipped with mutual authentication functions to ensure secure communication between devices. This guide provides information on how to set up mutual authentication between devices.

What is mutual authentication?

Mutual authentication is a secure process in which the server and client authenticate each other before encrypted communication takes place. This is achieved by providing a device certificate and authentication function to prove their identity.

Mutual authentication is a two-way authentication. It is actually a secure process in which the server and client authenticate each other before encrypted communication takes place.
To this end, in the network environment, both the server and the client must be able to provide a device certificate and authentication function to prove their identity.

Hanwha Techwin’s latest devices are equipped with a device certificate and provide a mutual authentication function. This provides the ability to restrict or check invalid server or client connections.

Server authentication is supported from NVR (Intel-based) and SSM Appliance*SSM v2.10.7 or later products, and client authentication is supported from WN7 X series model.

Mutual authentication between Camera and Video recorder

Follow the steps below to set up mutual authentication between Camera and Video recorder:

1. Connect the camera where the device certificate is installed and the video storage.
2. In the camera, set HTTPS and mutual authentication mode.
3. In the video storage device, register the camera with manual registration and set mutual authentication mode.
4. Check the authentication result on the video storage set live screen for camera authentication result and in the camera web browser based on the camera access client IP address for video storage authentication result.

How to connect and set up

Connect the camera where the device certificate is installed and the video storage.

Camera setup

1. The camera sets HTTPS and mutual authentication mode as follows.

   • Check “HTTPS”
   • Select certificates as HTW-default
   • Check “Mutual Authentication” & select “Allow only mutually authenticated connections”.
   • Mutual authentication options(Server: Camera / Client: Video storage, SSM)

   1. Allow all connections
      The server allows encrypted communication with the client regardless of whether or not the authentication of the certificate delivered from the client is successful. However, whether the authentication was successful or not can be checked based on the IP of the client connected to the server.

   2. Allow only mutually authenticated connections
      The server determines whether or not to allow the client to access the server according to the success of the authentication of the certificate received from the client. At this time, authentication checks whether the client’s certificate is a certificate issued by Hanwha and whether the validity period has expired.
      When authentication fails, encrypted communication between the server and the client is terminated.

   3. Allow only mutually authenticated connections (including Device ID authentication)
      The server determines whether or not to allow the client to access the server according to whether the authentication of the certificate delivered from the client is successful. At this time, authentication checks whether the client’s certificate is a certificate issued by Hanwha and whether the validity period has expired. Also make sure it matches the client’s MAC address. If authentication fails, the encrypted communication between the server and the client is terminated.

Mutual authentication after releasing HTTP mode If you select ② or ③ options, web browser access becomes impossible, and connection is possible after factory reset of the camera.

Video storage setup

1. When registering a camera in the storage device, set as follows.
   • Only Manual registration is supported with Mutual Authentication.
   • Protocol: Wisenet
   • HTTP: 80
   • Streaming mode: HTTP

Device authentication result

• Camera authentication result
  You can check the camera authentication result on the video storage set live screen as follows.

• Video storage authentication result
  The authentication result for the video storage device can be checked in the camera web browser based on the camera access client IP address.

  • When set to “Only allow mutually authenticated connections” mode, encrypted communication is possible only with clients equipped with device certificates. It is impossible to check the storage device authentication result through a web browser, and success or failure can be determined because the encrypted communication between the camera and the storage device has not been terminated. However, if you want to temporarily check the authentication result through a web browser for convenience, you can check the authentication result on the web browser screen as follows if you additionally set the HTTP mode in the camera.

  • In case of web browser access through HTTP mode, it is not encrypted communication, so be careful about security.
    No lock(-): No certificate (HTTP mode)
    Red lock( ): Certificates that do not support device authentication (authentication failed)
    Green lock( ): Certificate that supports device authentication (authentication successful

  • In case of connection to a storage device that supports device authentication (192.168.38.224), the success of mutual authentication is confirmed through the green lock.

  • In case of connection to a storage device that does not support device authentication (192.168.38.207), check the failure of mutual authentication through a red lock.

  • In case of web browser access without certificate (192.068.38.163), there is no lock mark
