摘要：

数据中心内有海量高价值数据,但存在数据孤岛问题。高价值数据共享是解决数据孤岛问题、挖掘数据潜在价值的有效途径,而实现数据共享的前提是保证数据共享过程的安全与可信。传统的数据共享模型往往采用集中式架构,这种架构容易产生信任及安全问题。区块链是一种具有去中心化、难以篡改、难以伪造、可追溯、可审计等特点的分布式技术,其为数据的安全共享提供了一种可靠的解决方案。然而,现有的基于区块链的共享方案难以保证共享过程的安全。针对以上问题,文章提出了一种面向数据中心场景的基于区块链与博弈论的高价值数据共享模型。首先,该模型使用区块链技术保证共享流程的可追溯、机密性和安全性;然后,运用博弈论给出相应的激励方案,调动数据持有者共享高价值数据的积极性;最后,将文章所提模型与其他现有的数据共享模型进行对比分析,通过对比分析验证了文章所提模型是功能齐全、安全高效的,能够更好地应用于数据中心场景。

Abstract:

Despite the huge amount of high-value data in a data center, there exists the issue of isolated data island. High-value data sharing is an effective way to solve the isolated data island issue and exploit the potential value of data. However, the prerequisite to realizing the full sharing of high-value data is to ensure the security and trustworthiness of the data sharing process. Traditionally, data sharing models tend to adopt the centralized architecture, which are prone to trust and security issues. Blockchain is a distributed technology with features such as decentralized, hard to tamper, hard to forge, traceable and auditable. It provides a reliable solution for data security sharing. Nevertheless, limited application scenarios and lack of security guarantee are limitations of blockchain-based data sharing solutions. In response to the above problems, the high-value data sharing model based on blockchain and game theory for data centers was proposed in this thesis. Firstly, the model used blockchain technology to ensure the traceability, confidentiality and security of the sharing process. Secondly, the model mobilized data holders to share high-value data by applying the game theory to give the corresponding incentive scheme. Finally, the model was compared with other existing data sharing models. Through comparative analysis, it is verified that this model has full functionality, security and efficiency, and can be better applied to data center scenarios.
