区块链基础设施安全的分布式可信计算基础

Decentralized Trusted Computing Base for Blockchain Infrastructure Security

Thomas Hardjono, Ned Smith

摘要:

如今,人们对区块链技术越来越感兴趣,认为它可能是未来全球金融生态系统的基础。然而,为了使这个未来的金融生态系统真正全球化,具有高度的互操作性和稳定性,需要解决与基础设施安全有关的一些挑战。一个关键方面涉及参与区块链点对点网络的系统的安全性和鲁棒性。在本文中,我们讨论的概念,分散的可信计算基础的TCB概念在可信计算的扩展。我们探讨了去中心化的TCB如何有助于(i)强化区块链基础设施中的单个节点和系统,以及(ii)在组成区块链系统的节点的P2P网络中进行安全的面向组的计算。

英文摘要:

There is a growing interest today in blockchain technology as a possible foundation for the future global financial ecosystem. However, in order for this future financial ecosystem to be truly global, with a high degree of interoperability and stability, a number challenges need to be addressed related to infrastructure security. One key aspect concerns the security and robustness of the systems that participate in the blockchain peer-to-peer networks. In this paper we discuss the notion of the decentralized trusted computing base as an extension of the TCB concept in trusted computing. We explore how a decentralized TCB can be useful to (i) harden individual nodes and systems in the blockchain infrastructure, and (ii) be the basis for secure group-oriented computations making within the P2P network of nodes that make-up the blockchain system.
