Maxim Integrated's DS28E35 DeepCover Secure Authenticator

The DS28E35 from Maxim Integrated is a powerful cryptographic solution designed to provide robust security to safeguard your electronic systems. As part of the DeepCover® embedded security solutions, the DS28E35 offers an advanced set of features aimed at protecting your product integrity through secure challenge-and-response authentication and high-grade encryption.

This secure authenticator integrates a FIPS/NIST compliant SHA-256 hash engine, which is coupled with a 1024-bit asymmetric (ECC-P256) hardware engine. These cryptographic tools work together to ensure that the device can handle complex cryptographic operations with ease, making it ideal for applications where security cannot be compromised, such as medical devices, financial systems, and other sensitive electronic products.

Key Features:

• Robust Security: The DS28E35 utilizes Maxim's patented ChipDNA™ physically unclonable function (PUF) technology. This ensures that the cryptographic key is protected against invasive physical attacks, as the key is derived from the unique characteristics of the chip itself and is not stored in memory.
• Asymmetric Key Authentication: The device supports public/private key (ECC-P256) cryptography, providing a high level of security for authentication processes without the need for secure key storage on the host side.
• Flexible Memory Organization: It comes with user-programmable and read-only memory options, offering flexibility for storing sensitive data, such as application data, certificates, and manufacturing information.
• High-Speed Communication: The DS28E35 features a 1-Wire® interface, allowing for fast and efficient communication through a single data line plus ground.
• Low-Power Operation: Designed for energy-sensitive applications, the device operates at low power, making it suitable for battery-powered devices.

With the DS28E35, Maxim Integrated continues its commitment to providing secure and reliable solutions for your electronic products. Whether you're looking to protect intellectual property, ensure supply chain integrity, or secure data communications, the DS28E35 offers a sophisticated and cost-effective approach to meet your security needs.

By incorporating the DS28E35 into your design, you can rest assured that your products will be safeguarded against unauthorized access and counterfeiting, thereby maintaining your brand's reputation and customer trust.
