In a recent study conducted by CSA, they examined ways in which blockchain can facilitate and improve IoT security. The report explores tactics to consider when attempting to secure connected devices using blockchain technology. The study uncovered some drawbacks with blockchain-facilitated security, yet found some inherent benefits from it. It revealed that due to hardware limitations of the IoT, when several hundred thousand or so IoT devices are connected, many of these end points could be incapable of functioning as transaction nodes. As such, they could fall outside the secure blockchain. On the flip side though, many devices would benefit from the security offered by blockchain services through APIs from upstream transaction notes of networks or by specialized intermediaries. Those upstream capabilities can be used to secure many connected IoT devices and communications.
Two of the hottest technology trends today are the rise in Internet of Things (IoT) and blockchain adoption. A recent report by the Cloud Security Alliance (CSA) brings these two areas together—in a potentially good way.
The study by CSA, an organization that raises awareness of best practices to help ensure a secure cloud computing environment, examines the ways in which blockchain can facilitate and improve IoT security. Securing this highly connected environment, in which potentially thousands of objects will be linked via the Internet, is something many IoT practitioners are concerned about.
