Cypress Semiconductor, a leader in advanced embedded system solutions, provides a secure microcontroller (MCU) solution to promote the application of the LoRaWAN™ open protocol to promote smart city and industry 4.0 applications.
ESCRYPT integrates its secure LoRaWAN key configuration and management application programming interface (API) with Cypress’s PSoC® 6 BLE MCU, enabling customers to easily protect and manage their LoRaWAN keys and quickly deploy a secure LoRaWAN system. PSoC 6 BLE MCU is the industry’s lowest power consumption, highest flexibility, built-in Bluetooth low energy (BLE) wireless connection dual-core MCU, and integrates hardware-based security features, including isolated execution environment, secure component functions and accelerated encryption engine.
Smart cities and industrial Internet of Things (IoT) applications using LoRaWAN networks require processing of sensor collection, control drivers, and RF stack operation. The radio frequency stack uses two advanced encryption standard AES-128 encryption keys for security operations, one of which is used to authenticate the packet data to the network server, and the other is used to decrypt the packet when it reaches the application server. Cypress PSoC 6 MCU ensures that only encryption operations can use these keys, and these keys cannot be accessed by other programs. The RF stack performs signature and encryption in the MCU isolated execution environment to protect sensitive information. In addition, the safe boot function of PSoC 6 MCU ensures that it can be started in a safe state. In addition to these security functions, PSoC 6 MCU can process BLE offline communication data, and realize the sensor hub function through its additional processing capabilities, thus forming a complete single-chip LoRaWAN host MCU.
ESCRYPT LoRaWAN Key Management System (KMS) is a cloud-based security service suitable for key management in the life cycle of any LoRaWAN ecosystem. It can be used for the secure configuration and registration of any LoRaWAN network equipment and the secure storage of key materials in the LoRaWAN ecosystem. The key material will never be leaked, and only authorized users can access sensitive IoT data.
Cypress and ESCRYPT are successively demonstrating PSoC 6 MCU-based secure LoRa modules from their partner Onethinx. The module can be connected with the Cross-Domain Development Kit (XDK) provided by Bosch Connected Devices and Solutions Co., Ltd. XDK is a multi-sensor module using intelligent wireless transmission technology. XDK can record sensor data, such as vibration, direction, temperature, light intensity or air pressure data from microelectromechanical systems (MEMS) sensors, and use the ESCRYPT configuration system to safely connect to Onethinx’s LoRa-based application server.
