Edge Devices

Following is a brief explanation of the Edge Devices component of asvin architecture.

The edge devices are end points in the Device Security Booster architecture and, in an IoT network, are tasked to control, manage and solve a physical task. Usually, many edge devices shall have a small footprint and must be easy to manage in remote areas under often extreme environmental conditions. For example: industrial process monitoring sensors, smart meters, Lora node etc. asvin provides libraries for a wide range of edge devices to facilitate the technical requirements necessary to interact with the Device Security Booster infrastructure securely and efficiently. The asvin libraries act as an interface between the edge devices and the Device Security Booster. The asvin SDK makes it easy to use APIs to interact with the Device Security Booster update infrastructure. The SDKs are developer friendly and allow for new IoT devices to connect with Device Security Booster infrastructure quickly to take direct advantage of a ready-to-run, update distribution network. The key features of asvin SDK is that It is a generic solution and not limited to any specific hardware platform e.g. Arduino, ESP, STM, Arm Cortex-M3, M4 etc. and software protocols.

The Device Security Booster libraries installed on edge device provides following functionalities:

1. Device Update Management

   • Securely register devices on Device Security Booster

2. Check for Firmware Updates

   • Regularly poll for updates in configurable time intervals

3. Download and Install Firmware

   • Download and store updated versions of firmware

   • Install the firmware based on traffic and availability of edge device

4. Collect Health Statistics

   • Send timely health updates of edge device on Device Security Booster e.g. firmware version in use

   • Device Security Booster generates insights from the data which can be used to extend life cycle of IoT devices and for preventive maintenance.
