Abstract
Access control is a mechanism that is used to decide which agent has access to which resource with some specific operations. This paper is devoted to the investigation of quantum cryptography in access control. We develop three quantum protocols and use them for key distribution, identity authentication and digital certification, respectively. We analyze our protocols by the graphical language of categorical quantum mechanics. These protocols are unconditionally secure and implementable by the current technology.
Highlights
We study the application of quantum cryptography in access control in cloud computing
We further develop the model of access control in cloud computing proposed by Hota et al (2011), by using quantum cryptography to grant access to agents
We present our quantum protocols in the framework of categorical quantum mechanics (Abramsky and Coecke 2004; Coecke and Duncan 2008; Selinger 2011; Coecke et al 2011; Backens et al 2016), which is the study of quantum foundations and quantum information using category theory
Summary
We study the application of quantum cryptography in access control in cloud computing. Models of access control in cloud computing are developed in Wang et al (2009) and Hota et al (2011). We further develop the model of access control in cloud computing proposed by Hota et al (2011), by using quantum cryptography to grant access to agents. The structure of the rest of this paper is as follows: After a brief review of the background knowledge on quantum computation and categorical quantum mechanics, we present three quantum protocols for key distribution, authen-.
