Omron Adds Secure RFID Protocol to EPC Gen 2 Reader

The company says the interrogator is the first on the market to include support for the data-protecting protocol, developed in Japan and expected to be available on tags made with Hitachi's µ-chip Hibiki.

Jun 10, 2008Tokyo-based RFID hardware provider Omron has added support for the Secure RFID protocol, developed by Japan's Ministry of Economy, Trade and Industry (METI), to its Omron V750 series of ultrahigh-frequency (UHF) interrogators compliant with the ISO 18000-6C and EPC Gen 2 standards. METI developed the protocol in collaboration with electronics firm Hitachi, to enable users of passive UHF EPC Gen 2 tags to protect data stored in tag memory.

Hitachi's µ-chip (pronounced mu-chip) Hibiki IC for UHF ISO 18000-6C and EPC Gen 2 tags supports the Secure RFID protocol, and other chipmakers are reportedly developing chips that will support that protocol as well. Omron is the first reader manufacturer to announce support for the security protocol, though there are not yet any tags on the market that do so. The protocol is available openly and royalty-free to anyone who will use it in a reasonable manner, says Gary Andrechak, product manager with Hitachi America.

According to Andrechak, there are other reader makers currently developing products that support the Secure RFID protocol, though he says he can not name them. In September 2007, NEC announced its plans to offer a multiprotocol interrogator that would read and write to the µ-chip Hibiki tags and support the protocol (see NEC Announces Development of Tri-frequency RFID Interrogator). According to Joseph Jasper, an NEC corporate communications representative, this model should be available by the end of 2008.

In 2003, METI brought together representatives from Hitachi, Dai Nippon Printing, Toppan Printing and NEC, in order to develop low-cost RFID chips that could be widely employed in the supply chain. The group, dubbed the Hibiki consortium, attended a 2005 meeting of the ISO 18000-6C standardization committee to propose that an alternative to that standard—one that would remove one of the data-encoding methods included in the ISO 18000-6C specification (see Japan Offers ISO a Gen 2 Alternative).

Doing this, the group said, would allow chipmakers to build an IC 40 percent smaller than that used for a conventional ISO 18000-6C tag, and this would lower tag costs. (The group estimated it could drop the cost of an ISO 18000-6C chip down to 5 yen, based on production of 100 million per month, by using its proposed chip design.) However, the International Organization for Standardization (ISO) ratified the 18000-6C standard without including the Hibiki consortium's proposal.
