Short Answer Question

What is IoT, and give examples of its applications?

The Internet of Things (IoT) refers to a network of interconnected computing devices, mechanical and digital machines that are given unique identifiers and are able to transmit data over the network without human intervention. The application range of IoT is very wide, including smart homes (e.g., lighting and temperature that can be remotely controlled via smartphones), industrial automation (e.g., sensors and actuators for monitoring and optimizing production processes), wearable devices (e.g., smart watches and fitness trackers for tracking fitness levels and health), and many more.

How does blockchain technology enable naming in IoT?

Blockchain can enable naming of IoT devices by providing a secure and decentralized namespace. Each device can have a unique identifier on the blockchain, similar to a wallet address in cryptocurrency. This approach prevents name conflicts and ensures the authenticity and verifiability of device identities.

Briefly describe the role of smart contracts in IoT services.

Smart contracts can automatically enforce the terms of an agreement in an IoT service, such as a service level agreement (SLA) or payment terms. For example, when one device requests data or a service from another device, a smart contract can ensure that payment is automatically made after the service is provided.

How do distributed databases improve the scalability and resilience of IoT systems?

Distributed databases can store data on multiple nodes in an IoT network, thereby improving the scalability and resilience of the system. If one node fails, other nodes can still provide data access, thereby minimizing downtime and increasing data availability.

What is the concept of self-describing hardware? How does it simplify the integration of IoT devices?

Self-describing hardware refers to hardware that is able to communicate its own capabilities and specifications to other devices. This approach can simplify the integration of IoT devices by eliminating the need for manual configuration and integration.

What role does a Trusted Execution Environment (TEE) play in IoT security?

TEE provides a secure area in which sensitive operations such as key generation, encryption, and authentication are performed. It protects IoT devices from malware attacks and other security threats.

What is a permission guide? How does it enable decentralized access control in an IoT network?

A permission guide is a distributed protocol or smart contract that defines the rules, terms, and conditions for interactions between devices or agents in an IoT network. It can use blockchain technology to record and enforce access rights, eliminating the need for a central authority.

Explain the concept of "floating services" and their application in IoT.

A floating service is a distributed service that moves on the Internet, negotiates resources to perform tasks and receives payment based on the work completed. For example, an image recognition floating service can negotiate access to IoT devices with image processing capabilities and receive payment based on the number of images recognized.

How does a decentralized network access proxy (DNAP) enhance the security of IoT networks?

DNAP can enhance the security of IoT networks by using blockchain technology to verify device identity and authorize access rights. It prevents unauthorized devices from accessing network resources and provides a secure communication channel.

Briefly describe the advantages of blockchain-based databases in IoT environments.

Blockchain-based databases can provide secure, transparent, and tamper-proof data storage in IoT environments. It can track data provenance, ensure data integrity, and facilitate trusted data exchange between devices.
