Silicon Labs EFR32xG21B SoC & xGM210P Modules with Secure Vault

Silicon Labs EFR32xG21B SoCs and xGM210P Modules with Secure Vault help address the challenges of a changing landscape and keep pace with regulations. Silicon Labs has introduced Secure Vault, a platform for securing and future-proofing loT devices. Secure Vault features Secure Key Management. Cryptography is core to security, and a foundational element to cryptography is the secrecy of its keys. Protecting those keys is the primary objective of any security system. Secure Vault takes advantage of a unique digital fingerprint generated by a physically unclonable function. This is used to create an AES symmetric key that physically disappears when the system powers down. The AES symmetric key doesn’t even exist when the chip is off. This is an extremely effective solution to the key management challenge. The function can scale to support a vast number of keys as required by the developer application. Secure Vault also includes a tamper detection system so the key cannot be reconstructed once the device is shut down after a tamper event. Secure Vault is the most advanced suite of hardware and software security protection available today.
