Security chip integrates European utility protection profiles

LONDON — With more and more energy utilities adopting smart metering and technologies, the potential for cyberattacks increases significantly. Hence, enabling security within the connected devices becomes critical, especially with the global smart metering system market set to reach $21 billion by 2024.

To address this, chip vendors are increasingly developing IoT security solutions, with the latest being STMicroelectronics, which has introduced the STSAFE-J100 security-on-a-chip device featuring pre-certified protection profiles for German BSI and French Enedis smart-utilities specifications.

Several countries have begun enforcing the implementation of smart meters. By adopting automated technologies, energy utilities stand to benefit from helping energy conservation, improving customer service, and providing better load management; consumers can also make consumption decisions based on real-time information.

The new ST chip integrated into IoT devices like smart meters, data concentrators, and utility gateways gives objects an unalterable identity that can be authenticated; it also handles encrypted communications and provides secure storage. Customizable with market-specific applets, the STSAFE-J100 secure element combines CC EAL5+ certified hardware and a CC EAL5+ certified secure operating system. Device designers can use ST’s pre-certified profiles or create their own security profiles.

The device is backwards-compatible with its predecessor, ST’s Kerkey embedded secure element, to preserve customers’ existing investment in software and development expertise. The new chip adds extra memory, offering up to 66 kB of user data storage; it executes cryptographic algorithms faster, leveraging its updated and higher-performing secure microcontroller embedding dedicated hardware accelerator.
