摘 要
随着网络攻击的日益复杂化和多样化,网络检测数据的共享成为提升网络安全防护能力的重要手段,但传统数据共享机制在隐私保护和信任管理方面存在显著不足。为此,本文提出了一种基于区块链的网络检测数据共享与隐私保护机制,旨在解决数据共享过程中的信任问题和隐私泄露风险。研究通过构建联盟链架构,将参与方纳入分布式网络中,利用智能合约实现数据访问权限的动态管理和透明控制,同时结合零知识证明技术确保敏感信息的安全性。此外,为提高数据共享效率,设计了基于差分隐私的数据脱敏算法,以平衡数据效用与隐私保护之间的矛盾。

Abstract
With the increasing complexity and diversification of network attacks, the sharing of network detection data has become an important means to improve the protection ability of network security, but the traditional data sharing mechanism has significant deficiencies in privacy protection and trust management. To this end, this paper proposes a blockchain-based network detection data sharing and privacy protection mechanism, aiming to solve the trust problem and privacy leakage risk in the data sharing process. Through the construction of alliance chain architecture, participants are incorporated into the distributed network, and smart contracts are used to realize the dynamic management and transparent control of data access rights, while combining zero-knowledge proof technology to ensure the security of sensitive information. In addition, to improve the data sharing efficiency, a differential privacy-based data desensitization algorithm is designed to balance the contradiction between data utility and privacy protection.
