Maxim's PUF technology enables multiple layers of protection to provide the most advanced key protection technology in a cost-effective format for use in IoT, healthcare, industrial, and IT systems.
As IoT applications continue to proliferate, vast numbers of devices are being deployed in uncontrolled and hostile environments, making them more vulnerable to physical attacks. These attacks are more sophisticated than software threats, such as poor encryption implementations or default password attacks. Designers want better system defenses for their mission-critical applications, where exposing secret encryption keys can bring down networks, ruin reputations, bankrupt businesses, and even negatively impact people's lives.
The MAX32520 with ChipDNA offers multiple layers of protection through its PUF technology, the industry's most advanced key protection technology for safeguarding secrets used in cryptographic operations. It utilizes a tamper-proof PUF key for flash encryption, secure boot for the root of trust, and serial flash emulation. Furthermore, the inherent physical security of the PUF key eliminates the need for a battery to actively destroy secret key materials under attack. Until now, the most sensitive applications have always required a battery to provide this higher level of secret key protection.
Key Advantages
Tamper-proof: The secret keys generated by the ChipDNA PUF circuit are highly resistant to physical attacks, ensuring that the keys protecting data and systems are beyond the reach of attackers.
IP Protection: Flash encryption with PUF protects sensitive information with encryption keys that resist even advanced physical inspection and intrusion, providing the strongest form of IP security available.
Advanced Encryption: The secure DeepCover microcontroller can protect all user data, as it is equipped with hardware accelerators and TRNG compatible with SP 800-90A and SP 800-90B for AES-256, ECDSA P-521, and SHA-512.
Memory: It offers up to 2 MB of secure flash memory, allowing advanced applications to run in a highly secure environment.
Cost-effective: Built on an advanced process node, this secure microcontroller offers advanced security features, a 120 MHz ARM Cortex M4 processor, and ample memory. It eliminates several components, such as a battery, a tamper monitor IC, and system management microcontrollers, that are often found in security-sensitive applications.
