While the IoT market continues to grow, a large number of devices are being installed in unregulated areas, even in potentially risky environments, making them more vulnerable to physical attacks. These attacks are more threatening than software tampering such as general key cracking and default password attacks. Designers hope to provide stronger system defense capabilities for some key data and operations to prevent network paralysis, company reputation damage, property damage, and even negative impacts on human life that may be caused by key leakage.

The ChipDNA-based MAX32520 provides multiple layers of protection through its PUF technology, using the industry’s most advanced key protection technology to provide the most secure keys for cryptographic operations. The device uses a tamper-resistant PUF key for flash encryption, and the secure import feature supports root of trust and serial flash emulation. Additionally, the inherent physical protection of PUF keys can actively destroy keys without the need for batteries when the system is under malicious attack. To date, even the most secure protection schemes require battery power to achieve this highest level of key protection.

main advantage

·Anti-tampering: The key generated by ChipDNA PUF circuit has strong anti-physical attack ability, ensuring that the key used for data and system protection will not fall into the hands of hackers.

IP Protection: Flash encryption with PUF technology makes protected sensitive data resistant to the most advanced physical detection methods, providing the most reliable IP protection on the market today.

Advanced cryptographic functions: DeepCover secure microcontrollers are equipped with SP 800-90A and SP 800-90B compatible TRNGs (True Random Number Generators), hardware accelerators that support AES-256, ECDSA P-521 and SHA-512 algorithms, capable of Protect all user data.

Large storage capacity: Provides up to 2MB of secure flash memory to ensure advanced applications run in a highly secure environment.

Efficient: Based on advanced process node technology, the safety controller offers advanced safety, a 120 MHz ARM Cortex M4 processor and ample memory space. components commonly found in other security-sensitive applications, such as batteries, tamper-monitoring ICs, and system management processors, are eliminated.

Evaluation

“IoT developers desperately need robust security solutions to enhance their design protections, while having difficulty finding professionals with the relevant skills to help them successfully bring their products to market,” said Tanner Johnson, senior analyst for IoT cybersecurity at Omdia. : “With Maxim’s flash-encrypted PUF and secure mount technology, developers can significantly reduce time-to-market by eliminating the need to redesign systems or develop code.”

“The attack techniques faced by IoT systems have become more sophisticated, and every day system attack tools are flowing from academia to open source.” said Kris Ardis, executive director of Maxim Integrated’s Microprocessor and Security Products Group. “The ChipDNA-based MAX32520 provides A solid step forward. Based on the most advanced key protection technology designed for IoT applications, it effectively protects your data and IP and helps designers defend against future system threats.”
