There are many different connection protocols on the market for different smart home products, which makes it increasingly complex to realize the interconnection and security of smart home products. 71% of consumers (according to incontrol data) are concerned about the theft of personal information when using smart home products, and many products are too complicated to install and use.

Leading suppliers and potential suppliers to the smart home industry have joined forces to take further action on the interoperability of smart home products with a new standard, the Internet Protocol (IP)-based Matter standard.

True Interoperability and Security Needs

While the idea of ​​using network technology to automate the home has been around since the mid-1970s or even earlier, modern smart home connectivity products designed to improve the quality of life for occupants require the Internet, especially the Internet of Things (IoT), to become a reality. However, today's smart home products are often complex to operate, not secure enough, and in many cases incompatible with each other. Users buy a device and go home, only to find that devices of different brands do not communicate with each other. Sometimes the setup is complicated. When it was finally set up, it was discovered that the new device would not work with existing smart home products (such as smartphones, thermostats, security systems, etc.). Sometimes incompatibilities are due to a lack of industry uniform standards. But the reason why smart home products are incompatible with each other is also because there are too many standards for smart home interconnection, such as connection standards alliance, Z-Wave, Thread, Wi-Fi, Bluetooth, and so on. These standards are often not linked to each other.

Matter: A secure interoperable connectivity standard for future smart homes

The Matter Working Group was formed by the Connectivity Standards Alliance (formerly the "Zigbee Alliance") to bring together the many different network factions to address interconnectivity and security issues. The working group is composed of experts from more than 170 large market players, including Apple, Amazon, Google, Infineon, Johnson Controls, Schneider Electric, LG Electronics and other giants. Among them are companies that allow ecosystems, devices and chips to work together to create open smart home standards. In addition to the usual glossary of terms found in any standard, one of the first things Matter addresses is the definition of terms so that all developers use the same vocabulary to describe key networking items.

Matter: Typical User Experience

In a typical Matter usage scenario, after a user brings back a new product (see Figure 1), the QR code on the back of the product can be scanned with a smartphone. The QR code is unique to the device and can represent the identity of the device for secure network distribution. Press the pairing button on the device to prompt it to start the installation. After receiving this prompt, the smartphone uses the encrypted information contained in the QR code it scans to establish a secure connection with the device; at the same time, it verifies the identity of the device, confirming that it is indeed a Matter authenticated device; and determines which device it belongs to (in this case is the coffee machine); then send all the necessary information (Wi-Fi password, etc.) for the coffee machine to join the network. That includes giving the coffee machine a new set of credentials, allowing it to communicate securely with any other smart home device. At this point, the coffee machine can communicate securely with the smart speaker, so that the smart speaker can start a specific brewing program, and the coffee machine has become one of the reliable members integrated into the smart home.
