Can Blockchain ensure security of IoT devices?

Blockchain, which is most familiar for Ethereum and bitcoin, offers an intriguing solution for IoT security. Blockchain contains strong protections against for the data tampering, locking access to Internet of Things devices (IoT), and allowing compromised devices in an IoT network to be shut down.

Numerous Internet of Things devices device over a network can be connected and spread over distributed fabric where all the Internet of Things devices transactions such as registration, authentication, sharing of resources, authorization, alert and more, can be written in ledger and remain unaltered. Any change in the transaction can be easily tracked. This ensures security. A permission blockchain allows consensus and permission membership services. Decentralized ledger allows data to be stored and spread everywhere. It is transparent and accessible to users.

How to implement Blockchain for IoT Safety

Blockchain technology began to be known with the advent of crypto coins mining since it is its main technology. But now, it also has much to do with the IoT.

The amount of data processed by IoT devices is enormous, all supplied for chain and exposed to attacks by cybercriminals. It’s context where the possibility arises to take advantage for the Blockchain architecture to authenticate, standardize and protect the adoption of data handled by the devices.

For Internet of Things devices safety, the blockchain is able to monitor the information collected by the sensors, without allowing them to be duplicated by any wrong data. Sensors can also transfer data by using Blockchain technology, without the need for a trusted third party.

In addition, we must add device autonomy, data integrity, virtual identity and point-to-point communication, all to get rid of technical deficiencies and bottlenecks. Blockchain and devices related to the IoT are addressable and are able to list a history for connected equipment, opening a bank so that in the future problems can be solved.

Coordination between devices

Blockchain technology stands out its ability to solve scalability, reliability and privacy issues. It enables coordination between devices, as well as tracking millions of connected devices and processing transactions.

This is a decentralized approach in which cryptographic algorithms are implemented so that customer data enjoy greater privacy. It’s an approach that eradicates faults and offers a resilient ecosystem.

The connectivity it provides is unprecedented because the Blockchain is based on the optimal platform, which is efficient considering solutions for the IoT require coordination so that the devices work integrated, without causing problems. It’s a secure infrastructure, far from the centralized model.

Processing transactions

Blockchain records these and digital interactions so that they are carried out in a safe, auditable, transparent, efficient and interruption-resistant manner.

Each block registers the operations with a time stamp and verifies that they are in the correct sequence, without manipulations. If someone wants to add a transaction to the chain, everyone in the network validates it through an algorithm; the approved transactions are gathered for the block and distributed to each node in the network.

The new block and successive blocks are validated with a single fingerprint corresponding to the previous block. There are billions of transactions per device, and adopting a standardized; point-to-point communication model would reduce installation or maintenance costs in huge Big Data centres, as well as the storage of devices that make up the IoT networks, preventing errors in nodes dragged by a collapse and arrest.

So that there is no theft and much less impersonation for the each transaction that takes place, it’s proposed to use some kind of consensus or validation of peer-to-peer communications, so that the privacy and security of large networks of the IoT persists.

A trend towards protection

For more transparency, convenience and security, Identity Management is systems chosen by companies to control access management.

Blockchain Identity is one of those trends, for its ability to store information in chains for transactions that prevent its modification when verified. The structure stores the data equitably, preventing server leaks.

In addition, it’s also important to mention Authentication systems, which require the verification for data, as well as the protection for company and staff information, approved by consensus as a right by the General Data Protection Regulations.

Data Tracking

All devices that can communicate with ledgers, entrenched in Blockchain, the devices used in IoT end up being safe in transactions.

All heavy work falls on technology, through machines, without the need for a human to execute the processes. The information provided by the customer can be tracked so that the experience is smooth and continues as private and inviolable; furthermore, using storage or encryption, every part of the chain can rely on the data.

The blockchain is ally for solving scalability or trust issues. The keys will always be private and nobody will be able to overwrite the codes, offering this way the security dreamed in operations of the IoT.

More advantages of Blockchain on Internet of Things devices?

• Blockchain Identity is one of the trends in high-capacity technologies like authentication systems. These aspire to become a law, as they encompass the protection for information that benefits businesses and individuals.
• Its public, so those participate can see the blocks, but not the actual content of the transaction, as they are protected for the private keys.
• The network is secure; the user’s identity will always be private
• It’s decentralized and there is enough trust.
• Network participants reach a consensus to approve transactions.
• The database expands, although records are kept. If someone wanted to modify for the last records, the cost would be much higher.
• It allows you to share the use for multiple files.
• It guarantees robustness or stability of resources, eliminating the flow of traffic to one or lowering the delay.
