ARM has released a new IoT device management solution, mbed Cloud. The mbed Cloud can securely and efficiently simplify the connection of any IoT device to the cloud, allowing service providers to easily manage devices and fully unlock their value throughout the life of the device.
The Internet of Things revolution is gaining momentum, and the Internet of Things is now connected to billions of devices worldwide, and this number is growing every day. For us, obviously there will be more equipment coming out to improve people's lives.
Networking: A variety of wireless networking options are emerging, and a new round of low-cost wireless technology is emerging, including cellular networks such as LTE Cat M and LTE-NB that are optimized for the Internet of Things, Thread, 6LoWPAN, and BLE. Consumable mesh networks and low-power wide-area networks (LPWA networks) such as LoRa. Some of these networking technologies offer low bandwidth connectivity.
Cost: The popularity of IoT devices and technologies in the market has driven module prices down to lower unit numbers. The use of unlicensed spectrum reduces the cost of continuous networking.
Low power consumption: Energy-efficient networking solutions paved the way for new use scenarios where discrete zero-maintenance equipment is required.
Connecting all of these devices and serving them is an opportunity and a challenge for ARM! The mbed Cloud is ideally suited to address the many challenges of expanding IoT deployments.
The mbed Cloud is an end-to-end product that is a holistic approach to developing the Internet of Things. It is designed to accelerate the development of secure, standards-based innovative devices and cloud applications.
Devices in the Internet of Things need to be updated and secured throughout their life cycle. The mbed Cloud meets common device management needs from the perspective of the Internet of Things. Its optimized network utilization is ideal for small-capacity devices with limited power consumption, making it easy to meet the needs of low-power devices and battery-powered devices.
Some development efforts require developers to be proficient in security and knowledge of device software and hardware architecture, and mbed Cloud can meet these more challenging needs. In addition, its features are dedicated to the Internet of Things, such as identity management, remote wireless software updates, management of production line tools and security assets, and intelligent supply chain licensing.
Mbed Cloud Service - Connect
Mbed Cloud Connect is a powerful command and control service between devices and mbed Cloud. It reliably and securely transfers device data, allowing you to manage and use it in IoT applications. It is at the heart of the mbed Cloud and is based on a set of industry-standard modules optimized for IoT devices and networks.
Large IoT device networks contain devices from multiple vendors. The mbed Cloud uses standard application-level protocols, which are key to preventing vendor lock-in (vendor lock-in means that a customer is dependent on a vendor for products and services and cannot be used without a large switching fee). Another supplier's products and services).
The mbed Cloud uses OMA Lightweight M2M to communicate with the device. The protocol and its modules are as follows:
· OMA Lightweight M2M (LWM2M) - An application layer communication protocol between an LWM2M server and an LWM2M client optimized for IoT devices. The protocol uses lightweight modules and an efficient resource data model.
· Limited Application Protocol (CoAP) IETF RFC 7252 is a private network transport protocol for restricted and restricted networks.
· Datagram Transport Layer Security (DTLS) protocol IETF RFC 6347 is implemented by mbed TLS to provide communication privacy for datagram protocols. The protocol enables client/server applications to communicate in a manner designed to prevent eavesdropping, tampering or message forgery.
Mbed Cloud Service - Provision
Mbed Cloud Provision provides secure device asset management. Ordinary people will call these "secrets."
These tips are very useful when new equipment comes out in the production hall and is turned on for the first time. Mbed Cloud Provision assigns a secure identity to the device and creates a trust between the mbed Cloud and the device. This trust is a key enabler of multiple services over the life of the device.
The mbed Cloud Provision will implement the following services:
- Services based on device-sensitive data that should be shared with data consumers (not service providers).
- Activation of services or features that have associated costs over the life of the device.
Some examples of possible services:
- Advanced inventory management - Simplify the supply chain based on the reduction in inventory units by enabling features after shipment rather than on the production line.
- Management of sensitive data - Securely lock sensitive information (Personal Identity Information (PII) or Sensitive Personal Information (SPI)) from the device to the cloud. Once uploaded to the cloud, access to sensitive information is limited.
Quote Stephen Covey's famous quote: "Trust is the glue of life. It is the most important element of effective communication and all relationships."
Mbed Cloud Service - Update
IoT devices have a product life cycle of up to 20 years. In order to enrich these devices, unlock more development potential, and address defects in your equipment, you must replace the device software. Remote wireless software updates are the only cost-effective way to distribute and install new software.
Mbed Cloud Update provides an insurance and secure software update mechanism. This service includes an end-to-end update schedule for managing and monitoring the update process. It can be updated via wireless, USB or cable. The Update client is pre-integrated in the industry's first-line IoT operating system.
