Renesas’ Synergy programme boosts IoT device security, cloud connectivity

September 05, 2017 // By Graham Prophet
Renesas’ Synergy Software Package v1.3.0 includes NetX Secure TLS, MQTT connectivity, Wi-Fi/Cellular/BLE frameworks, and support for additional Synergy microcontrollers.

This update of the Synergy platform includes the Synergy Software Package (SSP) version 1.3.0, which integrates Express Logic’s NetX Secure Transport Layer Security (TLS) and Message Queue Telemetry Transport (MQTT) for NetX Duo. SSP v1.3.0 also adds Wi-Fi, LTE cellular and Bluetooth low energy (BLE) wireless application frameworks that simplify adding or exchanging radio frequency (RF) modules in IoT devices. Low power management is improved by adding the Power Profile application framework for the Synergy MCUs’ complex low-power modes. The Synergy Platform also includes software and development tool support for three additional MCU groups – S5D5, S3A6, and S128. New low-cost S5D5 and S3A6 target board kits and S128 development kit reduce development cost barriers.

 

SSP v1.3.0 integrates NetX Secure to safeguard connected IoT device communications over public networks and the Internet. Developers can deploy NetX Secure to authenticate the sender’s and receiver’s identity, and prevent eavesdropping and tampering with data sent across the network. NetX Secure uses the TLS protocol to achieve socket layer security while using the NetX Duo TCP/IP network stack. TLS provides security three ways: by establishing secret keys between the client and server, applying hashing algorithms to detect alteration or forgery of packet content, and remote host identity using digital certificates. The MQTT protocol enables lightweight machine-to-machine (M2M) communication across small IoT edge devices powered by MCUs. This combination of TLS and MQTT protocols ensures secure and efficient communication from edge to cloud.

 

The wireless application frameworks in SSP v1.3.0 enable developers to add, or swap RF modules from various suppliers into their projects by providing a set of uniform APIs that abstract low-level hardware details. This makes it easy for Synergy Platform users to evaluate popular RF modules and adapt to changes in availability of specific RF modules with minimum impact to application code. SSP v1.3.0 also makes the Wi-Fi application framework native to the SSP and adds new frameworks for cellular
