Developers of industrial, medical, and IoT products now have an added level of IP and device integrity protection with the DS28C36 DeepCover secure authenticator from Maxim Integrated. It provides a targeted set of asymmetric-key and symmetric-key cryptographic tools in a low cost and compact solution. Asymmetric public-key features are supported with the P256 based elliptic curve cryptography (ECC) algorithm and symmetric secret-key with SHA-256. The DS28C36 provides two authenticated GPIO pins with optional secure state control and level sensing as well as a unique function to enhance secure download/boot features. The device also integrates sophisticated countermeasures to protect against invasive and noninvasive security attacks.
