Blockchain and Internet of things

The traditional centralized security model common in the many organizations today will thrive hard to meet the demands of the internet of things, or IoT. And, with so many devices that are created to be unobtrusive, removing them from the circulation could be tough if they are captured in a botnet.

Blockchain, and the combination of cryptographic techniques behind it, offers an intriguing substitute for the traditional systems, since blockchain is created for decentralized control, a security plan based on it can be more scalable than a traditional one. Additionally, blockchain’s strong protections against data tampering would help prevent a defective device from disrupting a home or transportation system, etc. by giving out misleading information.

Ahmed Banafa, IoT expert and lecturer at San Jose State University said that “Blockchain is promising for IoT security for the same reasons it works for cryptocurrency: It provides assurances that data is legitimate, and the process that introduces new data is well-defined,” who wrote a popular insights of the potential for blockchain to resolve IoT security challenges.


How will it influence IoT?


The issue of IoT security needs solving since the data flowing from sensors as well as embedded processors can change the way urban planners lay out hospitals and bus stops.
Bitcoin gives a simpler problem to solve than IoT security. With bitcoin, blockchain simply moves wallets of currency from one unknown owner to another. Full-fledged device authentication, security as well as the control layers are more difficult to understand.

In their model of a blockchain-secured smart home, a high-powered block miner dethrones the usual internet router or media center to manage all local network transactions. This device not only manages the internal blockchain but also controls communication between home-based IoT devices and the outside world. It also authorizes new IoT devices and could curtail or cut off devices that are behaving badly.


Amalgamation of two trending digital powers


And although IoT devices are miracles of engineering, they are still underpowered compared to the hardware powering successful blockchains. Blockchain processing tasks are computationally difficult and time-consuming. Many devices lack the processing power to directly participate in a blockchain. This is for good reason: The heavy computational load helps protect integrity.
