This software achievement could accelerate the development of more robust and secure low cost, low powered cellular IoT products and systems, and play a critical role in unlocking significant new markets for smart industrial and consumer products. For example in areas such as real-time asset tracking and monitoring, utility metering and smart city technology.
Rust is a very-high-performance alternative to systems programming languages such C and C++, which avoids the memory safety issues that plague those languages, and without the complexity and overhead of Java.
42 Technology’s application demo is based around the recently launched Nordic Semiconductor nRF9160 System in Package (SiP) device, which features a full multimode LTE-M/NB-IoT modem to connect to the mobile network, assisted GPS and an ARM Cortex-M33 processor. The ARMv8-M architecture’s TrustZone security features are particularly exciting, allowing applications and associated services to operate securely, protected from hacking, misuse and corruption.
In recent field trials, 42 Technology’s Rust application made secure encrypted connections to Amazon cloud services via an early LTE Cat-M network that is being rolled out across the UK by O2, the mobile network operator. The board also supports NB-IoT which is being launched by Vodafone and other operators.
