NXP Semiconductors A71CH Plug & Trust Secure Element
NXP A71CH Plug & Trust Secure Element offers a ready-to-use solution to quickly and easily deploy secure IoT connections. The A71CH solution provides a Root of Trust (RoT) at the silicon level with security functionalities such as encrypted key storage, key generation, and derivation to protect private information and credentials for mutual authentication. Developed to secure peer-to-peer or cloud connections, the A71CH chip comes with the required credentials for autonomous cloud onboarding and peer-to-peer authentication.
The A71CH solution integrates security measures to protect the IC against many physical and logical attacks. Some of these measures include securely storing and provisioning credentials, securely connecting IoT devices to cloud services, and performing cryptographic node authentication. Designers can use the A71CH solution with various host platforms and host operating systems to secure a broad range of applications. The NXP A71CH Plug & Trust Secure Element is especially well-suited for use in smart home and industrial applications including sensor networks, gateways, IP cameras, smart cities, and home appliances.
