Samsung adopts blockchain for smart home security.
Smart homes are becoming more and more common and many of the devices we use on a daily basis have the goodness of being connected as elements of control and verification of our routine activities. However, as our connectivity increases, so does our concern for maintaining peace of mind when using the ecosystems of all these interconnected items.
As homes fill up with connected devices such as televisions, lights, air conditioners, doorbells, vacuum cleaners, washing machines, dryers, refrigerators and many others. Each of them becomes a doorway through which malware or a computer thief can potentially enter. The attraction is not in capturing that device for the original action for which it was designed, but for its ability to communicate with other devices; each element can be a place of access for a computer thief, who could install software that from some connected element manages to link to another device where you have something more than functionality, what I mean is for example they can access our personal computer where we have sensitive and important data for us.
At the start of its annual conference for developers, the Samsung Developer Conference 2022, in San Francisco, Samsung announced a new version of SmartThings, its platform for linking devices of a connected home, which will implement blockchain technology to correct one of the biggest problems of digital insecurity that has modern home automation.
Understanding that security and privacy are priorities for its users, Samsung is taking its device security experiences to a new level.
Samsung believes that protection must be collaborative, end-to-end and real-time, so its approach is constantly evolving to stay ahead of threats and keep its users safe. As such, Samsung’s smart devices are protected by the Samsung Knox security platform, which provides defense-grade security certified for use by major government agencies around the world.
In a review about Blockchain, we managed to remember that it is a technology directly associated with cryptocurrencies, but not only that, as it has a lot more functionality that new projects adopt every day and it is being used a lot to preserve security in supply chains of components, legal documents among many others. The basic concept is that all changes that can occur in a blockchain are validated by all members, and the records are stored in all of them; thus, to violate a blockchain it would be necessary to modify the records of all members simultaneously.
Samsung Knox Matrix will function as a user’s private blockchain system, in which their connected devices enhance security through multi-layered mutual monitoring. To protect the user’s smart home from unauthorized access and make the login process more convenient, this layer will share credentials from device to device and protect sensitive information even between trusted devices. Regardless of whether your Samsung devices are based on Android, Tizen or another operating system, Samsung Knox Matrix will be able to provide a unified security SDK. All in all, Samsung will continue to advance common security standards for all Samsung connected devices.
So, what Samsung is proposing with its new Knox Matrix platform: a cross-validation system that prevents unknown software from installing itself on one of these devices and taking control of it. In theory, it won’t be able to, because the rest of the network will notice it instantly: it will lack the original credentials generated by that private Blockchain. It seems complex, but Samsung assures that all this will be automatic and invisible.
This blockchain technology is adopted to increase security in smart devices, allowing each of them to control and share access data with each other.
For now, there are no dates as to when this system will be available, and they are working to recognize the maximum number of elements that can be connected to this internal blockchain to serve your smart home, since their vision is not only to hardware elements of the brand.
