Maxim released the industry's first security authenticator IC that supports the sha3-256 encryption engine

DS28E50 using ChipDNA ™ PUF technology, embedded designers can help primary or no encryption experience for safety certification, peripheral devices to prevent counterfeit and illegal use of chip
Beijing, China, October 18, 2018, Maxim Integrated Products, Inc. (NASDAQ: MXIM) announced DS28E50 DeepCover ® secure hash algorithm 3 (SHA3-256) of secure authentication IC, help the embedded system designers to easily and deploy productively in its integration in the design of the industry's most advanced strong encryption security certification. With sha3-256, DS28E50 can realize the latest challenge-response security authentication technology, provide the strongest defense capability in the form of a secure IC solution, effectively prevent counterfeit chips, illegal use and other application problems, and is an ideal choice for primary or non-encryption experienced designers.
Today's embedded systems are constantly under attack from hackers and the means are increasingly complex. Designers are working to protect the integrity of their products by preventing fake products from the aftermarket. At the same time, the certification measures are enhanced to ensure that the sensors in this equipment are genuine and not inferior imitations. DS28E50 provides advanced features for embedded system developers to effectively guard against counterfeit chips, after-market counterfeiting and illegal use, and is widely used in the fields of intelligent, networked industries, medical and consumer equipment
In addition to providing the industry's first SHA3-256 security authentication IC, DS28E50 also integrated the Maxim ChipDNA ™ PUF (physically not cloning) patent technology, effectively prevent the common security chip IC level. ChipDNA technology relies on the simulation features of basic MOSFET semiconductor devices to protect the keys, and the simulation features of devices are generated naturally and randomly. The key to protect all data stored by DS28E50 is generated only when needed and disappears immediately after use.
Main advantages of DS28E50
High performance, strong encryption security: the sha3-256 solution compatible with the FIPS 202 provides a high performance, low complexity method that enables extremely advanced call-response security certification, effectively preventing counterfeit chips, monitoring, or limiting the use of peripherals. ChipDNA PUF technology can closely protect all sensitive data stored in the device against security attacks
Easy to implement: single contact, 1 - Wire ® simplified terminal communication application interfaces. IC includes a secure EEPROM for storing the application data in the terminal, providing a variety of configurable and irreversible storage protection modes. No device level firmware development (host side microcontroller needs firmware). In addition, delivery programming services are provided to simplify the management of security keys

Small, low power consumption, strong and durable packaging: IC power supply only 3.3 V, working in to 40 ° C to + 85 ° C temperature range, including + 8 kv for human body model (HBM) electrostatic discharge (ESD) protection, using 6 pins, 3 mm * 3 mm TDFN encapsulation   evaluation
 embedded security is undoubtedly one of the biggest issues in the IoT space, particularly in protecting intellectual property from damage." " "" sha3-256 is one of the latest and most reliable encryption algorithms available at the moment, and any scheme that USES it is in the lead," "said Tanner Johnson, senior cybersecurity technology analyst at IHS Markit.

 Maxim's latest security authenticator facilitates applications that require effective encryption for interrogation-response security authentication, which is applicable to protection of peripherals, sensor data, access control, and feature Settings." " "" with sha3-256 encryption engine and ChipDNA PUF technology, DS28E50 can achieve industry-leading security and provide strong protection for customer devices," "said Scott Jones, executive director of Maxim Integrated embedded security division.
