D&M Holdings Licenses Certicom Intellectual Property

Certicom Corp. (TSX: CIC) today
announced that Japan-based D&M Holdings, Inc, maker of the popular Denon,
Marantz, McIntosh, and ReplayTV brands, licensed Certicom elliptic curve
cryptography (ECC) intellectual property to implement the digital rights
management (DRM) standard, DTCP, in many of its products. DTCP (Digital
Transmission Content Protection), which protects digital video and audio
interfaces on consumer electronic devices, uses ECC for authentication and key
agreement.
Digital interfaces on consumer electronic devices eliminate the need for
analog conversion and pave the way for interoperability between consumer
electronic and personal computers in the home. While this new approach offers
higher quality content, there is a risk that perfect digital copies of content
could be created if the interfaces aren't protected.
To counter this risk, the industry has introduced DTCP as a DRM standard
to protect digital audio and video content as it moves from device to device.
Today DTCP is primarily used for Firewire interfaces but is expected to extend
to USB and wireless digital interfaces. Certicom's security technologies, used
for authentication and key agreement, help to protect audio/video content from
illegal copying, and tampering.
"Consumer electronic companies are under pressure from content providers
to protect digital content. Consequently, this is an emerging market with
great potential for ECC and Certicom," said Ian McKinnon, president and CEO of
Certicom. "The agreement with D&M Holdings is a key milestone in our strategy
to continue to expand into the consumer electronics market, particularly in
Asia. As this industry moves more of its content to digital, we can expect to
see a greater demand for Certicom and our ECC expertise."
ECC is a computationally efficient form of cryptography that offers
equivalent security to other competing technologies but with much smaller key
sizes. This results in faster computations, lower power consumption, as well
as memory and bandwidth savings, thereby making it ideal for today's
resource-constrained environments of consumer electronics. Certicom's patent
portfolio covers many key aspects of cryptography and ECC in particular,
including software optimizations, efficient hardware implementations, methods
to enhance the security, and various cryptographic protocols.
D&M Holdings has licensed ECC-based patents and patents pending, and will
pay Certicom royalties on product shipment over the life of the patents.
