DNP to Begin Offering Built in Module for Safe M2M Communications

Easily connected to Cloud, while also preventing tampering of mission critical data

Dai Nippon Printing Co., Ltd (DNP) will begin offering the M2M Secure Module, a built in module designed to prevent data tampering and achieve safe machine-to-machine (M2M) services.

[Developmental Backdrop]

In recent years we have seen an increase in highly convenient services that use M2M technology to exchange data obtained via sensors between network-connected equipment. For example, vehicle dispatching services that use positional information for automobiles, and maintenance management services that use operational information for factory and agriculture equipment. Looking ahead, expanded use of M2M is anticipated in financial settlement areas and the medical and healthcare fields. When handling large amounts of personal information, however, it is also expected that we will see increased risks of attacks, such as malicious third parties illegally obtaining data via networks, and/or data tampering. In order to prevent such attacks, DNP has taken advantage of the security technology and know-how developed in its smart card business and will begin offering the M2M Secure Module, a module that can be safely connected to a cloud service by embedding it in the equipment used, as a solution for safe M2M services.

[Overview of M2M Secure Module]

The M2M Secure Module is a product designed for embedding the following functions into equipment, and is mounted with a resistant secure chip against external illegal access.

  • A secure boot function for confirming the presence of illicit equipment tampering when activating or resetting.
  • The extracting of necessary data from amongst data obtained using an equipment-based sensor, and the use of the secure chip to encrypt the same.
  • Connecting to cloud services and sending encrypted data by use of a cloud connection application.

The module is offered in a board format, with the security chip and communications components mounted on the print board. The client can decide the performance of the secure chip and memory volume in line with equipment OS, type and size of the data being handled, and cloud service specifications, and the module is offered in a customized hardware specification. The secure chip also integrates a secure application uniquely developed by DNP, and is compatible with I2C, SPI, GPIO and UART equipment interfaces.

[Cloud Service Validation]

In cooperation with ITOCHU Techno-Solutions Corporation (CTC), Inventit Inc., Qualica Inc., and Hitachi High-Technologies Corporation, companies that variously provide M2M cloud services, DNP has confirmed that the following operations have been correctly carried out as a part of data communications between the M2M Secure Module prototype and the cloud services offered by each company.

  • A secure boot function for confirming the presence of illicit equipment tampering when activating or resetting.
  • The encryption of data obtained via the equipment thermal sensor and camera, and forwarding to the cloud service using the secure chip.
  • The decoding of the encrypted data on the cloud service.
  • The remote resetting of the M2M Secure Module, based on reset instructions from the cloud service.

[Looking Ahead]

DNP will market the M2M Secure Module to manufacturers of smart meters, automobiles, FA equipment, multi-functional machines, ATMs and vending machines. And apart from commercialization of one chip-type modules suitable for embedding in compact equipment, such as wearable devices, DNP also plans to commercialize gateway terminals that include board-type modules. The Company will also offer remote personalization services for the safe writing of personal information and key information in the secure chip of the M2M Secure Module. These services will be offered in combination with such cloud applications as M2M cloud and thermal monitoring systems.

DNP aims for sales of 1 billion yen by fiscal year 2017 from M2M related business.
