ECDSA authenticator protects devices against security attacks

Mouser now stocks the DS28E38 DeepCover secure ECDSA authenticator from Maxim Integrated. Developed to protect devices against security attacks, the device is an Elliptic Curve Digital Signature Algorithm (ECDSA) public key-based secure authenticator. It incorporates Maxim’s patented ChipDNA physically unclonable function (PUF) technology. The authenticator is the first secure authenticator to integrate the company's ChipDNA capability to protect all device stored data from invasive discovery. The technology involves a PUF that enables the device to achieve cost-effective protection against invasive physical attacks. Attempts to probe or observe ChipDNA operation modifies the underlying circuit characteristics, stopping discovery of the unique value used by the chip cryptographic functions. The device's secure ECDSA authenticator enables engineers to add an extra layer of protection to applications such as IoT nodes, device management, secure peripherals, and medical sensors.
