“Blockchain-based API Gateway for IoT Devices” – S. Lee, D. Kim, 2018

With the development of the Internet of Things (IoT), the number of devices connected to the network is constantly growing. This increases the likelihood of cyber attacks and security breaches. This creates a need to develop new technologies designed with safety and reliability in mind. One such option is to use blockchain technology to create API gateways for IoT devices. This article discusses the concept of a blockchain-based API gateway for IoT devices, proposed by S. Lee and D. Kim in 2018.

Key ideas:

  1. Blockchain Technology as the Foundation for API Gateways
    Blockchain technology offers unique capabilities to ensure the security and reliability of IoT devices. Thanks to decentralization, transparency and cryptographic data protection, blockchain technology can serve as the basis for creating API gateways that can withstand cyber attacks and ensure the confidentiality of user data.
  2. Creating a decentralized network
    A blockchain-based API gateway involves creating a decentralized network in which each device is a participant in the blockchain network. Thus, control and data processing is distributed among devices, which increases system reliability and reduces the likelihood of system failure.
  3. Device Identification and Authentication
    Using cryptographic keys and unique identifiers, the blockchain-based API gateway provides device identification and authentication. This helps prevent unauthorized access to devices and data, as well as control interactions between devices on the network.
  4. Data protection
    Data transferred between devices on a blockchain network is stored in encrypted form. This ensures data confidentiality and protects it from leaks and unauthorized access.
  5. Scalability and efficiency
    A blockchain-based API gateway allows you to scale the system at minimal cost and improves network efficiency through parallel data processing and the use of smart contracts.

Unfortunately, I do not have access to specific studies or articles, including “Blockchain-based API Gateway for IoT Devices” by S. Lee and D. Kim, published in 2018. However, I can provide a general description and analysis of the topic based on public knowledge about blockchain, API gateways, and IoT (Internet of Things).

The Internet of Things (IoT) is a global network of physical devices that collect and exchange data over the Internet. These devices range from simple sensors and controllers to complex machines and control systems. However, despite its many benefits, IoT faces significant security and scalability challenges.

API (Application Programming Interface) gateways serve an important role in integrating and managing communications between various IoT devices and external applications. They provide single point access to device functionality and also add a layer of security by managing authentication and authorization.

Blockchain, a distributed ledger technology known for its strength and high security against counterfeiting, offers a solution to a number of security and trust issues in IoT networks.

How a Blockchain-Based API Gateway for IoT Works

Blockchain as a means of access control

Using blockchain to control access to IoT devices can significantly improve security. Blockchain can be used to create a secure and immutable database of access rights, where every access change is recorded and verified by the network. This prevents unauthorized access and improves login tracking.

Decentralization

Blockchain introduces decentralization to the management of IoT devices, reducing dependence on centralized servers, which increases the network’s resistance to attacks and failures.

Transparency and audit

Every action performed through the API gateway is recorded on the blockchain, which ensures complete transparency of operations and the possibility of auditing. This is especially valuable in applications that require strict control over actions and their consequences, such as in medicine or finance.

Automation through smart contracts

Blockchain allows the use of smart contracts to automate IoT-related processes. Smart contracts can automatically execute when certain conditions are met, providing greater efficiency and reducing the possibility of errors or fraud.

Conclusion:

Blockchain-oriented API gateways for IoT devices represent a promising direction in the development of technologies that ensure the security and reliability of networks
