Abstract:

As a new type of digital infrastructure，the internet of computing （IoC） serves as the foundational support for the high-quality development of the digital economy. Its characteristics of logical centralisation，physical decentralisation and heterogeneous resources have disrupted traditional security boundaries，giving rise to complex risks. This paper systematically analyses security challenges across IoC’s three-tier architecture，synthesising a comprehensive risk framework. By integrating core concepts such as trusted computing，reliable operation，and AI-enabled security，it constructs a security and trustworthy framework for IoC while proposing governance pathways. This aims to provide theoretical guidance for security practices within IoC and lay a robust security foundation for building a integrated computing power network.

Key words: internet of computing, computing power network, risk governance, security and trustworthy
