Introduction to How Blockchain Can Secure IoT
Blockchain technology and the internet of things are two exciting technologies. According to industry experts, the two technologies are bound to revolutionize the world in the coming years.
Today, more and more people are purchasing smartphones and other smart devices. In this light, the Internet of Things is set to grow tremendously because of the need for enhanced security for such devices.
It is important to note that while technology is good, the safety of your data and your privacy is very crucial. The reliance on IoT networks can expose your data to security breaches.
This is where blockchain technology comes in. It plays a significant role in preventing data loss and other related security breaches.
How blockchain helps to secure IoT
Blockchain has the ability to increase the level of data automation and its overall security. This is based on the fact that it is:
The blockchain is decentralized therefore, it breaks data into small chunks and then carefully distributes them across computer networks. It doesn’t upload your information in a cloud available or in a single location.
Therefore, with the digital workspace, blockchain technology helps to secure all types of information. It also secures ledger transactions more efficiently.
When using blockchain, there is no need for a middleman. This means that you do not have to deal with a financial lender, since the system is decentralized.
Remember in the past, all IOT trust requests had to be aggregated into a single location. This would mean having a security intelligence location. Often, the security of even the most sensitive information would be compromised.
Blockchain, therefore, enables smart devices to protect themselves in different ways for enhanced security. This technology allows the devices to quarantine any suspicious nodes.
Five digital safety/security primitives
Blockchain also allows for five digital safety primitives including suitability, availability, accountability, confidentiality, and integrity.
When blockchain is used in IoT, a private permission-based block is used for accountability and auditability. This means that there is no unauthorized access to the network. As a result, every device is accountable for any action.
Blockchain also has a public data entry ledger for integrity purposes. Therefore, any correction or deletion of data is recorded. All entries are also recorded by the network.
Validation and encryption
Blockchain also allows for validation and encryption in the world of IoT. It can prove that data has not tampered with thanks to its effective distribution nature.
What’s more, you can always use a blockchain ledger to prove that the information you stored in the cloud has not been tampered with. The technology is simply very reliable, efficient, and allows for independent data verification.
Hard to hack
Generally, blockchain offers enhanced security to IoT because it is impossible to hack it. Remember, IoT is all about associating a specific smart device to the internet as well as other related devices.
Being a giant system connected to people and many other things, it is easy to share information. As a result, information can be easily hacked.
What’s more, whenever smart devices are implanted into other related systems, they can also represent themselves digitally. This exposes them to risks and controls from any place.
With such a connectivity point, your data is at risk. The good thing is that blockchain technology is very effective as it expands and enhances IoT security.
However, many companies outsource dedicated software development teams to uses advanced technology to ensure the decentralization of information.
There are nodes on the network that verifies all transactions. The technology is amazing and it is beyond the ability of today’s cybercriminals.
As a matter of fact, through the decentralized approach, all nodes or peers must always agree on any changes that need to be made.
In this case, even if a hacker tries to make a security attempt without permission, the other nodes will prevent it. Blockchain will prevent the data from being altered.
Blockchain also helps to build trust for IoT. It allows IoT devices to take part in communications and other essential exchanges as confided in different parties.
Blockchain saves a record of data exchange between different devices. With the information, it can later confirm and enhance trust between people, devices, and associations for enhanced security.
Blockchain can be public or private
While blockchain plays a significant role in ensuring anonymity, you can also use private blocks to restrict specific users from accessing your data.
This can be achieved through a decentralized node to the node network. As a result, any individual trying to access your information must always prove their identity.
A point to note is that the only way that blockchain can be altered is by having a majority of nodes at the same time, on the same network. This is impossible bearing in mind the strategies used by IoT mobile app development companies to ensure a unique own access code is used on different devices.
Blockchain simply allows IoT devices to understand how to behave at all times for enhanced security. This is because an IoT device usually operates a unique service model that needs a trusted administrator to manage the network.
With such authority and the security that blockchain offers, it becomes easy for the devices to behave in a way that does not lead to security breaches.
Blockchain ensures a secure IoT because of its top features that help to minimize possible security risks.
