Maxim announces the introduction of non-cloneable security ICs to protect designs from attack

The DS28E38 Security Authenticator uses ChipDNA ™ technology to provide a highly effective turnkey security solution that effectively protects the user's design

Maxim announces the DS28E38 DeepCover® Security Authenticator, an anti-physical attack solution that enables designers to easily and proactively secure proactive protection solutions at low cost, reliably protecting their intellectual property and products.

Cyber attacks continue to dominate the news headlines, with Internet of Things (IoT) devices at the heart of the attack - according to Cybersecurity Ventures, a U.S. investment advisory agency, the cost of cybercrime worldwide will reach $ 6 trillion by 2021. However, design security is still a remedy, and many engineers believe that the implementation of security solutions is expensive, difficult, and time-consuming, leaving the software under system protection. In addition, some systems that use secure IC protection may in turn suffer from the invasion of advanced wafer-level direct attack techniques that often acquire keys and security data from the IC.

The DS28E38 uses Maxim's ChipDNA PUF (Physical Cloneless Technology) to effectively protect against intrusive attacks because the ChipDNA-based root key simply does not exist in memory or any other static space. Maxim's PUF circuit relies on the analog characteristics of the underlying MOSFET semiconductor device to protect the keys, and the analog features of the device are naturally randomized. When needed, each device circuit will generate a unique key that disappears immediately after use. If the DS28E38 is subjected to an intrusive physical attack, it will cause the circuit's sensitive electrical characteristics to change, further deterring sabotage. In addition to the benefits of protection, ChipDNA technology also simplifies and eliminates the need for complex secure IC key management because the key can be used directly for cryptographic operations. ChipDNA circuit has proven its high reliability in process, voltage, temperature and aging. In addition, to improve the quality of encryption, the PUF output evaluation successfully passed the systematic NIST randomness test. With the DS28E38, engineers can incorporate anti-attack measures into their designs from the beginning. It is easy to integrate the IC into a customer's design with Maxim's single-contact 1-Wire® interface and incorporates simple, fixed-function commands that include cryptographic operations.

The main advantage

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.

Evaluation

"With Maxim's ChipDNA PUF technology, the DS28E38 Security Authenticator is very effective against physical or black-box reverse engineering attacks." Michael Strizich, president of MicroNet Solutions, said: "PUF generated data is protected even in the toughest internal attacks This is due to Maxim's proprietary security technology. "

"We did not need to spend too much energy, resources or time on hardware-based upfront system protection." Scott Jones, executive director of Embedded Security at Maxim Integrated, said: "With the DS28E38ChipDNA technology, designers can easily get their designs to the highest level In short, you can not steal keys that do not exist. "
