network security

The article proposes a comprehensive approach to solving the data protection problem in decentralized distributed information storage systems based on blockchain technology. A conceptual “SecureChain” model has been developed that integrates modern cryptographic protection methods with programmable smart contract logic for automated access management and data integrity assurance. The model employs a multi-level architecture including data layer, smart contract layer, network interaction layer, and user interface.

The main objectives of this article are to analyze and propose new solution to increase network efficiency and security. New approaches to the network designs are emerging with changing of network services and network availability requirements. To create network environment that can fully support ability to freely interconnect between various devices and inside different network types (BYOD (Bring Your Own Device), Internet of Things, etc.), the new mechanism of traffic analysis and control must be developed.
