Chipset authenticates peripheral devices

23 January 2013 Analogue, Mixed Signal, LSI

Maxim is sampling a new chipset that claims to provide the strongest levels of security when authentication of peripherals is necessary. As part of the manufacturer’s DeepCover security lineup, the chipset comprises the DS2465 secure coprocessor with integrated 1-Wire master and the DS28E15/DS28E22/DS28E25 1-Wire secure authenticators.

This secure chipset protects a revenue stream by ensuring that only licensed peripherals are used with OEM equipment. Many applications in consumer, medical, industrial and communications markets can benefit from this security.

OEMs can ensure that the peripherals used with their equipment are genuine and meet their performance and quality standards. The DS2465 coprocessor, used with any of the 1-Wire secure authenticators, quickly identifies unlicensed after-market peripherals that are not approved for a system.

An example application is a medical system for patient monitoring that uses replaceable sensors and peripherals. Using this DeepCover solution, the medical device will verify that the attached medical sensors are authentic and approved by the device manufacturer, and thus deliver the performance and safety requirements demanded by the application.
