As the number of connected IoT devices grows exponentially, security becomes a primary concern. IoT security requires an end-to-end approach. Security must be incorporated into every stage of development. Authentication and encryption are two key aspects that must be thought through at the hardware level as well as in software development. As security is a moving target, the ability to update firmware over-the-air (OTA) is a winning advantage.
The ATECC608A CryptoAuthentication device from Microchip Technology integrates ECDH security protocol with ECDSA. ECDH is an ultra-secure method to provide key agreement for encryption/decryption. ECDSA is sign-verify authentication for the Internet of Things (IoT) market, including home automation, industrial networking, and medical, as well as accessories and consumables authentication and more.
To meet increasing security requirements for Internet of Things products, Maxim’s MAXREFDES143# is an IoT embedded security reference design, built to protect an industrial sensing node by means of authentication and notification to a web server.
