Maxim Integrated Products has announced that it is now sampling a new chipset that provides the strongest levels of security when authentication of peripherals is necessary.

As part of Maxim’s DeepCover™ security products, the chipset comprises the DS2465 secure co-processor 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 will immediately 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 co-processor, used with any of the 1-Wire secure authenticators, quickly identifies unlicensed after-market peripherals that are not approved for a system.

Scott Jones, executive director at Maxim Integrated comments: “You need an implementation that is cryptographically sound, but it must also withstand an inevitable attack and physical tampering to obtain keys and secrets.”

Using this DeepCover secure chipset, 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.

Key Advantages include:

Advanced security: the DS2465 performs SHA-256 coprocessing to operate slave devices that provide SHA-256 authentication security; an integrated 1-Wire master communicates with 1-Wire slaves.

Design flexibility: the DS28E15/DS28E22/DS28E25 make it easy to add a device to a design with either the integrated 1-Wire IO of the DS2465 or one spare GPIO pin from a microcontroller or FPGA.
