Decentralized Trusted Computing Base for Blockchain Infrastructure Security
This addresses security challenges for blockchain infrastructure, potentially enhancing interoperability and stability in global financial ecosystems, but it appears incremental as an extension of existing TCB concepts.
The paper tackles the problem of infrastructure security in blockchain systems by proposing a decentralized trusted computing base (TCB) to harden individual nodes and enable secure group-oriented computations within peer-to-peer networks.
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.
