Zero-Knowledge Proof In IoT

What is Zero-Knowledge Proof?

Zero-Knowledge Proof (ZKP) is a cryptographic protocol that allows one party (the prover) to demonstrate to another party (the verifier) that they possess certain information without revealing the information itself. This concept, first introduced in the 1980s, has gained traction in recent years due to its potential to enhance privacy and security in various applications.

In the context of IoT, ZKP can be used to authenticate devices, verify transactions, and ensure data integrity without exposing sensitive information. For example, a smart home device can prove its identity to a central hub without sharing its private key, reducing the risk of data breaches.

Key Features of Zero-Knowledge Proof in IoT
