Maxim chipsæt giver sikker kommunikation mellem system og periferienheder

Maxim Integrated Products 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 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 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 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 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.

- Customers require secure authentication, says Scott Jones, Executive Director at Maxim Integrated.

- You need an implementation that is cryptographically sound, but it must also withstand an inevitable attack and physical tampering to obtain keys and secrets. Maxim leads the way in this field by ensuring that sensitive information is protected with strong cryptography and state-of-the-art tamper protection.

Advanced security: the DS2465 performs SHA1)-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.

Comprehensive physical tamper protection: thwarts the most probable security attack at the die level.

Minimalist interface simplifies implementation and reduces costs: the 1-Wire interface requires only one dedicated contact to operate.
