Secure quantum fog computing model based on blind quantum computation

As a computing service platform closer to users, fog computing has many advantages such as extremely low latency, good mobility, accurate location perception and wide distribution. It has developed rapidly in recent years. However, due to the wide distribution of fog nodes, complex network environments, and limited resources, the security of fog nodes is vulnerable to a variety of attacks, such as denial of service and abuse of resources. In order to effectively deal with these attacks, this paper proposes a quantum fog computing model based on blind quantum computation and verifiable quantum secret sharing. The model mainly relies on blind quantum computation to realize the security joint operation characteristics of multiple fog nodes, and the identity verifiable and channel detection protection features provided by the quantum secret sharing protocol, which can not only efficiently perform the functions of the classic fog computing, but also guarantee the security of information transmission and data calculation. Through the complete security analysis, the new quantum fog computing model proposed in this paper can effectively resist on a variety of fog computing attacks, thus achieving information security protection in both the content and process of fog computing.
