DNP Multi-Peer VPN Adopted by Auto Component Manufacturers

Facilitates Gathering of Drive Test Data in Secure Environment for Autos in Development

Dai Nippon Printing Co., Ltd. (DNP) is pleased to announce that the DNP Multi-Peer VPN, a Virtual Private Network-based security system designed to carry out authentication between communications equipment peers and management on a dedicated server, has been adopted for the first time by Japanese auto component  manufacturers.
By integrating this system into on-board communications equipment, it becomes possible to achieve a secure communications environment when communicating drive test data during the development of new models on a remote basis.

When developing new models, drive test data is collected and recorded by such recording media as OBD II (on-board diagnostics II), and CompactFlash memory cards. To date, when communicating this drive data on a remote basis, such as overseas locations, it has taken time to mail the recording media. As a result, it has been necessary to connect the test model to the network, and use a system capable of gathering drive data in real time at a separate location. Such drive data is confidential, and requires a secure environment, which has led Japanese auto component manufacturers to include DNP Multi-Peer VPN in their systems.

[DNP Multi-Peer VPN]

  • DNP Multi-Peer VPN is comprised of a software development kit for encrypting communications data, and a cloud environment or VPN management server installed in an in-house network environment. The server facilitates automatic authentication of multiple on-board communications equipment and peer-to-peer communications, precluding the need for special VPN devices. It is also possible to create a secure data communications environment at low cost.
  • By integrating DNP Multi-Peer VPN into on-board communications equipment, communications can be conducted in a secure environment, making it possible to prevent illegal access or the leaking of confidential information caused by interception of communications channels between automobiles and servers, and also between automobiles, themselves. 
  • Even in instances when the communications environment goes out of range while sending data, recovery is possible via an automatic reconnection function.

[Forward Looking Developments]

With the development of a society driven by the Internet of Things (IoT), and with the advent of the Connected Car that is linked to the internet and capable of receiving a variety of information services, there will also be an increased risk of damage to cars in motion from cyber-attacks. As a result, the promotion of IoT and boosting of information security have become a challenge for the automobile industry.
Beginning with DNP Multi-Peer VPN, DNP will continue to offer a variety of services to the automobile industry designed to create safe and secure communications environments, while also dealing with cyber-attacks. The Company aims for sales of 5.0 billion yen by FY 2020.
