2 ARM mbed: Connecting chip to cloud Device software Device services Third-party cloud services IoT device application mbed Cloud Update IoT cloud applications Analytics and rules App management mbed clients mbed OS, mbed Cloud Client Provision Web servers Scale-out Device silicon and hardware Connect Load balancing Data storage 2

3 mbed Cloud 3

4 mbed Cloud mbed Cloud simplifies management of IoT devices Connectivity, Provisioning and Firmware Update Standards-based approach Optimized for energy efficiency mbed Cloud Unique offering for a chain of trust for IoT Simplifies firmware update across complex networks 4

5 mbed Cloud Connect Simple, secure and energy efficient IoT connectivity solution for a diversity of devices, enabling unified connectivity from cloud applications Key features Standard based OMA LWM2M, CoAP and TLS/DTLS End-to-end channel security Secure device bootstrap Optimizes for small devices and energy efficiency IoT device communication via REST APIs to enterprise software and web apps 5

6 OMA Lightweight M2M LWM2M is a Device Management protocols optimized for IoT devices Manage IoT devices remotely and update over-the-air LWM2M enables interworking between compatible clients and servers Usage of Standard protocols is the key in preventing vendor lock-in Vendor lock-in - a customer dependent on a vendor for products and services, unable to use another vendor without substantial switching costs ARM is an active member in the OMA standard body activities ARM client and server implementation are standard compliant ARM participate in the on-going TestFests computability activities 6

7 mbed Cloud Connect is standards based OMA Lightweight M2M V1.0 Optimized for IoT CoAP RFC 7252 CoAP block wise - rev 16 CoAP over TCP - rev 01 CoAP observe - rev 11 CoRE resource directory - rev 04 Secure connectivity using TLS/DTLS V1.2 7

8 Network optimization: Cache mechanism 2. Send resource value with max-age mbed Cloud Connect 1. Get resource value 3. Resource value 4. Get resource value IoT Cloud Application Queue/ Cache 5. get value from cache 6. Resource value mbed Cloud connect cache mechanism increases device battery life time Reduces network utilization and hence reduces device usage of battery to yield longer battery life Optimized network utilization is ideal for mesh networks and battery powered sleepy devices 8

9 Integration with application cloud platforms mbed Cloud Client CoAP HTTP(S) IoT devices 9 Your Own Server

10 Making it easier for developers: mbed Cloud SDKs Speeds up application development on mbed Cloud Available in JavaScript and Python Open Source Apache 2.0 Functionality offered: 10 User and key management Connected and disconnected device and resource management Certificate creation and management Firmware image, manifest and update campaign management

11 Features of mbed Cloud Update Secure Authenticity, integrity and confidentiality protection Failsafe operation Reduce costs for rolling out updates Flexible Workflow Simple but powerful APIs to manage and monitor devices Conditional Updates Target groups of devices and apply rules to avoid interrupting critical device operations Monitoring Track the progress of updates and status on all devices Standards Support Transferable technology, reduced time to market 11

12 mbed Cloud Update components Cloud Set of REST based APIs Example web application (Portal) Accelerating proof of concept projects Service available when needed Service reliable and scalable Client Included as part of mbed Cloud Client Small and portable (PAL) Reference Bootloader Power Failsafe Built in recovery Tools Manifest creation/signing tool 12

13 Update Workflow using mbed Cloud Software Developer Developer Publish Firmware Update Service Device Apply Updates Code Development Prepare Update Package Publish Package Setup Campaign Distribute Package Verify Package Apply Recover Device Admin Manage Campaigns Device Admin/ Service Manager 13

14 mbed OS 14

15 mbed OS 5 mbed OS is built to address the disruptive jump in complexity for embedded software Cortex-M RTOS kernel Partner ecosystem Development tools mbed OS Portable drivers Developer community Open collaboration across the ecosystem accelerates IoT system development Management services IoT connectivity Integrated security 15

16 mbed OS Connectivity LAN WAN Ethernet BLE Cellular LoRaWAN WiFi Thread Sub-GHz 6LoWPAN NB-IoT 16

17 mbed OS Security Covers three main types of threat 1. Security of system, including ability to provision, manage and update devices (e.g. security fix) 2. Security of communications between device and cloud services 3. Security and integrity of device itself from untrusted or malicious code mbed OS Security mbed Client Lifecycle Security mbed TLS Communication Security mbed uvisor Device Security 17
