DS28S60Q+

DS28S60Q+ is a DeepCover® cryptographic coprocessor. It easily integrates into embedded systems enabling confidentiality, authentication, and integrity of information. With a fixed command set and no device-level firmware development required, the DS28S60 makes it fast and easy to implement full security for IoT devices. Communication with the device is performed using the industry standard SPI interface at up to 20Mbps with a simple set of commands that provide a comprehensive security toolbox utilizing HW-based cryptographic blocks. It integrates Maxim’s patented ChipDNA™ feature, a physically unclonable function (PUF) to provide a cost-effective solution with the ultimate protection against security attacks. It is used in applications such as Internet of Things (IoT) device security, key management and exchange, end-to-end encryption, end-point authentication, and prevention of counterfeit products.
