Recently, the rapid growth of network resources and the cybersecurity issues become more and more rigorous due to the rapid progress of Internet of Things (IoTs). How to integrate the network resources and enhance the defense capabilities effectively is an urgent problem. In this paper, inspired by the spread of friendly worms in the network, we put forward a novel concept of worm computing which is a decentralized computing platform. The worm computing model is able to integrate the useful information for resource sharing and cooperative defense, which can achieve the resource utilization refreshing, computing capacity improvement and network security enhancement. We use a blockchain platform to build a fundamental decentralization system and store collaborative data by delivering a private chain, which solves the problem of data sharing and trust computing in the traditional collaboration model by providing decentralized and credible services to ensure the unchangeable modification of transactions. We conduct experiments on resource utilization and collaborative defense of malicious URLs and the results validate the effectiveness of the proposed worm computing model in improving resource utilization and network security.

近年来，由于物联网（IoT）的快速发展，网络资源的快速增长和网络安全问题变得越来越严峻。如何有效地整合网络资源，增强防御能力是当务之急。在本文中，受友好蠕虫在网络中的传播的启发，我们提出了蠕虫计算的一种新概念，它是一种分散式计算平台。蠕虫计算模型能够整合有用的信息，以进行资源共享和协同防御，从而实现资源利用率的刷新，计算能力的提高和网络安全的增强。我们使用区块链平台构建基本的去中心化系统，并通过提供私有链来存储协作数据，通过提供分散且可靠的服务以确保交易的不变修改，解决了传统协作模型中的数据共享和信任计算问题。我们对恶意URL的资源利用和协同防御进行了实验，结果验证了所提蠕虫计算模型在提高资源利用和网络安全性方面的有效性。
