Technology Innovation: Infineon Helps Protect Consumers From Counterfeit Batteries and Other Electronic Accessories With World F
September 17 2008 - 4:27PM
Marketwired
Infineon Technologies AG (FRANKFURT: IFX) (NYSE: IFX) today
introduced the world's first chip that uses asymmetric
authentication featuring elliptic curve cryptography (ECC) and
integrated temperature sensor that can be used by battery and
electronics manufacturers to detect unauthorized accessories and
after-market replacements. This counterfeit detection capability
helps manufacturers ensure the intended user experience and protect
against safety risks posed by unauthorized and untested accessories
or batteries.
The new ORIGA(TM) SLE95050 family includes a version with an
integrated temperature sensor that can further improve the safety
level of batteries for electronic devices such as digital cameras,
mobile phones and portable computers. The ORIGA SLE95050 can also
be used for printer cartridges, replacement parts, medical
disposables, networking equipment or other accessories, such as
earphones, speakers, docking stations and chargers. With SLE95050
production start projected for the end of 2008, first consumer
products -- like digital cameras -- integrating Infineon's
authentication chips are expected to hit the shelves during the
second half of 2009.
"Security and safety have become a key challenge for designers
and developers of most systems and applications. We developed the
SLE95050 in response to our customers' request to help protect a
safe and consistent end-user experience. Our innovative asymmetric
cryptography approach, using two different keys for encryption and
decryption, provides improved security at reduced overall system
cost," explained Sandro Cerato, Vice President and General Manager
of the ASIC Design and Security Business Unit at Infineon
Technologies. "Our authentication solutions open up a new dimension
in brand protection and clone prevention for designers and
developers of many different types of systems."
ORIGA SLE95050: Improved Authentication and Temperature
Monitoring at Reduced System Cost
The ORIGA SLE95050 family uses ECC asymmetric authentication,
which uses two different keys (one public, one private) to encrypt
and decrypt information. ECC is a considerably more modern
encryption/decryption algorithm than today's asymmetric systems,
like RSA, and symmetric systems that use the same key for
encryption and decryption, like AES and DES. The weak spot of
symmetric cryptography is that the whole system is compromised,
once this key is retrieved. Using ECC significantly increases the
level of security as the private key is hidden in the ORIGA
chip.
The benefit of the ORIGA SLE95050 is that applications do not
require an additional security chip inside the host device, e.g.
the camera. With ORIGA, the implementation in the host device can
be realized in software without compromising security. The private
key is protected in the ORIGA SLE95050 chip which is integrated
into the accessory or the battery. For comparison, symmetric
solutions require an additional authenticating chip in the host
device for a secure implementation.
The ORIGA SLE95050 also complies with emerging battery safety
regulations, for example in Japan, that require temperature
monitoring of Lithium based batteries. It has a built-in
analog-to-digital converter that allows convenient temperature
monitoring from either its on-chip or an external sensor. This is
done by just sending a bus command via Infineon's proprietary
single wire interface. This single wire interface of the ORIGA
SLE95050 allows smooth system integration and remote powering over
this single line. With non-volatile memory (NVM) of up to 1 kbit
including NVM for write-protection and unique chip ID, ORIGA also
provides the added benefit of personalization by storing data about
the specific accessory, the logistics chain and the usage of the
accessory itself.
The SLE95050 operates at the temperature range from -25 �C to 85
�C and at an operating voltage range of 2.0 V to 5.5 V.
Availability
The ORIGA SLE95050 family today comprises two members. The
SLE95050F1 including the temperature monitoring feature and
SLE95050F2 without temperature monitoring. Samples of both devices
are available with production expected to start at the end of
2008.
