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 in software development. As security is a moving target, the ability to update firmware over the air (OTA) is a winning advantage.
Microchip's CryptoAuthentication ensures things and code are authentic, untampered, and confidential. The Atmel® ATECC508A features a wide array of defense mechanisms specifically designed to prevent physical attacks on the device itself or logical attacks on the data transmitted between the device and the system.
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.
