The A71CH from NXP Semiconductors is a ready-to-use secure element for IoT devices which provides a root of trust at the IC level.

It is intended for use in a wide range of security use cases, including securing a device’s connection to a cloud service, device-to-device authentication, establishing proof of origin and protecting against counterfeiting, secure key storage, secure management of credentials, secure data protection, and secure commissioning support.

The A71CH provides end-to-end security, from chip to edge to cloud: its integrated connectivity applet means that there is no need for the system developer to write security code or expose keys. Host software which is ready to deploy eases integration with a wide range of microcontroller and microprocessor platforms.

The A71CH also includes a complete product-support package which reduces design time and accelerates time to market.

NXP eases the design process in several ways. For example, the use of an OpenSSL engine and integration into mbedTLS make it easier to work with connectivity stacks. NXP also offers time-saving design tools such as sample code for important use cases, extensive application notes, and compatible development kits for i.MX and Kinetis® microcontrollers.
