NXP has unveiled a new EdgeLock secure enclave to help protect IoT devices. The autonomous on-die subsystem will be featured in NXP’s upcoming i.MX 8ULP, i.MX 8ULP-CS, and i.MX 9 processors, and will make it easier for developers to add strong security to edge applications built for a number of different industries.
To that end, the EdgeLock hardware is fully self-contained, with a dedicated security core, internal ROM and RAM, and symmetric and asymmetric crypto accelerators to guard against attacks through other channels. The secure enclave will support the other developer-programmed applications on the chip, storing keys and other assets in an isolated area that is separate from the parts of the chip that handle more direct real-time processing functions.
According to NXP, the secure enclave will provide developers with a preconfigured security framework that is compliant with the latest international regulations. As a result, it will simplify the certification process, and reduce the amount of time that device manufacturers need to bring new products to market. The enclave can provide coverage for many different kinds of IoT connections, keeping data safe whether the processor is interfacing with the cloud, another device, or a sensor for authentication.
EdgeLock is part of NXP’s broader EdgeVerse portfolio. The enclave can guard against physical and network attacks, and offers intelligent power management and tamper detection.
“We’ve engineered the EdgeLock secure enclave to simplify the deployment of robust security mechanisms and meet the ever-increasing demand for scalable, easy-to-implement IoT security,” said NXP VP and Head of Crypto and Security Wolfgang Steinbauer. “Embedded developers can now focus on their applications and time-to-market challenges, and let the EdgeLock secure enclave technology handle the underlying complexities of securing the IoT.”
EdgeLock is one of several products that NXP has released to promote the development of IoT devices. Most notably, the company has introduced improved i.MX RT106F and i.MX RT106L MCUs that will make face and voice recognition more affordable for device manufacturers.
