1. What is Azure Sphere:
For details, please refer to the official website Documentation: https://docs.microsoft.com/zh-cn/azure-sphere/
The following is a simplified version of the author's understanding, for reference only:
It is a comprehensive solution for IoT:
Use Azure Sphere to help protect your data, privacy, physical security and infrastructure, which is based on Microsoft in hardware, software and cloud decades of experiences is built, one-stop shop for the IoT device security solutions.
Azure Sphere is how to do it safe?
Start talking about its composition:
1. Safety networking MCU
2. custom Linux-based operating system
3. Cloud-based security services
Let's look at each constitute a separate program:
1. Certified MCU:
Hardware partners of Microsoft Azure Sphere authentication chip has built-in security technologies, it can be put for connection and dependable hardware root of trust .
Documents or information currently we see where are the MT3620 (MediaTek 3620),
Detailed information, see the document:
https://www.mediatek.com/products/azureSphere/mt3620
https://docs.microsoft.com/zh-cn/azure-sphere/hardware/mt3620-product-status
Rough estimation of the parameters of the MCU as follows:
2. custom Linux-based operating system
Azure Sphere OS adds layers of protection and ongoing security update, designed to create a trusted platform to provide new IoT experience.
3. Cloud-based security services
Azure Sphere security services transit facilities to trust cloud communications equipment to detect threats and security updates.
Microsoft's cloud-based service, Azure Sphere chip can communicate with in order to achieve the maintenance, update and control. Sometimes abbreviated as AS3.
To ensure the safety of the seven attributes:

Hardware-based root of trust
This will ensure that only genuine equipment to run the latest software before connecting to the rest of the Internet.
Defense in Depth
The more layer of defense, the harder it *** confidential access to the most sensitive equipment. The more layers of defense provided by the more sensitive areas.
Small Trusted Computing Base
Always try to keep the trusted computing base at a smaller scale, in order to reduce the maximum extent possible by *** surface, and reduce the use of bug or a feature of its possibilities ***.
Dynamic Isolation
Boundary between software components can prevent a component of vulnerability spread to other components. You can safely move and redraw the dynamic boundary.
Certificate-based authentication
The password may be a number of security systems weakest link. Verify need to manage equipment required for password-based authentication.
error report
Early detection, analysis and response to the error, which is to deter threats is essential, to avoid causing significant damage.
You can renew security
Ongoing software updates can be deployed, which is essential for strengthening the defense equipment and close loopholes.
2. Azure Sphere can do
1. secure networking capabilities: Azure Sphere MCU with networking functions can not be previously networked devices via the secure data transmission network Azure Sphere;
2. The application development support: Support for application development, Azure Sphere itself has many, many interfaces, such as GPIO like the typical IOT control system may be implemented;
Integration Scheme 3. Azure IoT: Azure Sphere can fit Azure IoT Hub DPS, Azure IoT Hub, Azure IoT Central used to construct a complete networking applications;

4. Azure Sphere Rate
Azure Sphere's first certified MCU (MT3620AN) pricing and support details.
When we add new MCU product lines certified to be expected pricing due to their function and manufacturer requirements vary.
| AZURE SPHERE SKU details | Pricing ** | support information |
|---|---|---|
| Azure Sphere MCU model MT3620AN | Less than $ 8.65 |
