Maxim ChipDNA technology generates a unique key for each IC, shutting down hackers

Security is an eternal topic. In recent years, domestic and international Internet users have suffered frequent incidents of hacker intrusion. Do you remember that 58 city-wide resume leaked in India? India's McDonald's 220W user receipt was leaked and the user's home camera was intruded and hacked, Cards, counterfeit credit cards, RFID intrusion, medical device intrusion, and even the US presidential election last year did not escape the hackers patronage, all kinds of scenes to make users scared. According to the Forrester report, more than 500,000 IOT devices have been attacked this year. Looking ahead, especially in the era of all-things interconnection, realizing the desire of 1 trillion IoT devices in 2035 can not be ignored.

Many engineers previously thought that security solutions were not only costly to implement but also difficult and time consuming to operate, leaving security issues to software for protection. Obviously software protection now is no longer enough to block hackers' efforts to develop innovative simulations and Mixed-signal products, technology Maxim has more than 20 years of experience in the development of secure ICs, recently released a security chip DS28E38, using ChipDNA technology, the security to a new level. Don Loomis, Vice President, Maxim Microprocessor and Security Products Group, said: "The ChipDNAPUF technology used by the DS28E38 is physically unclonable, making it an effective defense against intrusion attacks because ChipDNA-based root keys are not at all Exists in memory or any other static space. "

What is ChipDNA technology?

Don explained that ChipDNA technology is a non-cloneable technology that takes advantage of the random electrical characteristics of IC devices to obtain PUFs, generates a unique, repeatable root key for each IC when needed, and disappears immediately after use. Once invaded, will lead to changes in the circuit's sensitive electrical properties to further prevent damage behavior. Provide NIST-level encryption of ultra-high reliability.

The DS28E38 costs less than $ 1

The DS28E38 is the first chipDNA-based product to offer the following features

High Security: Encryption tools for ChipDNA include asymmetric (ECC-P256) hardware engine, True Random Number Generator (TRNG), descent counter with authentication protection, 2Kb Secure EEPROM (erasable programmable read only memory) , The only 64-bit ROM identification number.
Easy-to-implement, high-performance: 1-Wire 1-Wire operation eliminates device-level firmware development, simplifies key management and provides free host system software tools.
High Reliability: The PUF Key Error Rate (KER) is only 5 ppb over the entire time, temperature and voltage range.

The DS28E38 is suitable for any application areas such as consumer products, industrial products, peripherals and cables, medical equipment, supplier management and more. The DS28E38 is available in a 3mm x 3mm, 6-pin TDFN package and is available for $ 0.83 (1000 units, FOB USA). Users can purchase it through the official website and authorized distributors.

Security Whether in the PC era, the era of mobile Internet, or the future era of the Internet of Things can not be ignored, the DS28E38 provided by the United States effectively defend the physical or black box reverse attacks, multi-user acclaim.
