New Enhancing Security through Private Blockchain: Building a Secure Peer-to-Peer Messaging System with Advanced Blockchain Technology
Ko Ko Min, Hein Tun, Aung Ko Latt, Htoo Naing Aung · 2024
Nowadays, messaging apps are very popular, and client authentication is crucial. Many mobile apps use encryption for security, but they face security threats. This highlights the need for a trusted security method. In a blockchain framework, all data is automatically verified and controlled, with transactions recorded. Thus, a blockchain-based messaging system could be a solution. Software applications, known as Decentralized Messaging Applications (DMApps), are operated within a distributed computing environment, such as a blockchain network. DMApps integrated with a blockchain network can execute application logic that is ensured to be transparent, verifiable, and immutable. We’ve developed a secure DMApp supported by blockchain-based smart contracts on the Ethereum blockchain, ensuring data security. Our paper investigates how users can communicate securely through this system. We explore why blockchain enhances communication security and propose a decentralized architecture for secure messaging while overcoming the challenges of traditional approaches.
