HITAG co-processor HTRC12002B
FEATURES
General security concept
• Data encryption
• Encryption mutual authentication
• Password verification.
Additional features
• On-chip EEPROM to store secret data
• Uncomplicated host interface
• Sleep mode for reduced current consumption.
All secret keys are stored within the HTRC12002B.
GENERAL DESCRIPTION
The HITAG
(1)
co-processor is designed to perform all
computations of the read/write device in a system where
HITAG1 and HITAG2 transponders are used.
Access to related extended data sheet
This short data sheet will inform about the basic features
of the product and about the mechanical dimensions only.
Due to our marketing strategy to supply reader
manufacturerswithan IC based toolset for HITAG readers
the HITAG12002B is available without any license fees.
However, because of the security aspect of this product
Philips tracks the delivery of the extended data sheet
HTRC12002B, which includes all additional necessary
information to run the HTRC12002B.
In order to gain access to the extended data sheet, please
contact your local sales office in order to sign a
non-disclosure agreement.
The device performs all encryption computations needed
to access transponders and cards based on the HITAG1
respectively HITAG2 ICs in secure mode. Usually the
HTRC12002B is used in combination with the
HTRC11001T, which comprisesthe complete analog part
of a read/write device.
