Blockchain As An IoT Security Solution
By Sandeep Kasalkar
The potential use of blockchain for Internet of Things or IoT security solutions may come as a surprise if you haven’t kept up with the recent technological developments. Most of us are familiar with IoT, which powers smart homes, linked medical equipment, etc., and Blockchain, which powers cryptocurrencies. The use of blockchain for IoT security offers us an intriguing look at how several technologies may combine to produce future value-creating innovations. The use of blockchain in IoT security merits investigation since IoT security is a major problem and a barrier to the mainstream adoption of IoT.
Issues with IoT Security
The Internet of Things, or IoT as we refer to it, is made up of a variety of connected networks and gadgets. Device-to-device or M2M (machine-to-machine) communication is what defines it. Compared to other endpoint devices like smartphones, tablets, or laptops, each device’s resource pool is small. This is a result of their little size and insufficient memory and power.
In terms of energy use and memory needs, traditional security techniques used in the previous setups are a costly option for IoT security. Furthermore, a lot of security frameworks provide a single gateway because they are centrally located.
The entire IoT network may be accessed if a centralised configuration is hacked by only one piece of hardware.
Blockchain’s advantages for IoT security
- The main benefits that blockchain delivers to IoT security, according to our knowledge of its design, are
- Blockchain’s distributed and decentralised structure eliminates the potential of a single point of failure.
- Protects data integrity and is impossible to mess with
- Scalable in that nodes may be added when necessary
- Compared to conventional authorisation protocols, smart contracts offer effective authorization access rules to IoT devices with a great deal less complexity.
