Embodiment Construction

[0034] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:

[0035] In this embodiment, set {|0>, |1>} to be a set of orthonormal basis, denoted as C x ;{|i>,|j>} is a set of orthonormal basis, denoted as C y ;C x with C y There is the following relationship between the two:

[0036]

[0037] Equivalent to:

[0038]

[0039] C x with C y Satisfy the following formula:

[0040]

[0041] The two photon EPR entangled pairs in the quantum entangled photon pair are in the following entangled states:

[0042]

[0043] likefigure 1 As shown, the mutual quantum authentication process between CSP and DUser in the cloud model is as follows:

[0044] (1) Both CSP and DUser establish a shared secret key:

[0045] A shared secret key K needs to be established between the sender CSP (Alice) and the receiver DUser (Bob). AB , the establishment of the key can be achieved through the quantum distribution protoco...

Abstract

The invention discloses a quantum authentication method for access control between three elements of cloud computing, the three elements of cloud computing are data owner DOwner, data user DUser and cloud service provider CSP, including setting CSP and DUser as ERP entanglement pair and legally have the same ID number, conduct mutual quantum authentication between CSP and DUser; set DOwner and CSP as ERP entangled pairs and legally have the same ID number, and perform mutual quantum authentication between DOwner and CSP; when CSP and CSP When the mutual quantum authentication between DUser and the mutual quantum authentication between DOwner and CSP is successful, the quantum authentication between DOwner, DUser and CSP is successful; otherwise, the quantum authentication between DOwner, DUser and CSP fails .

Description

technical field [0001] The invention relates to the field of collar security communication, in particular to a quantum authentication method for access control between three elements of cloud computing. Background technique [0002] Cloud computing is an Internet-based model for the addition, use, and delivery of related services, often involving the provision of dynamically scalable and often virtualized resources over the Internet. Cloud is a metaphor for the network and the Internet. In the past, the cloud was often used to represent the telecommunication network in the diagram, and later it was also used to represent the abstraction of the Internet and the underlying infrastructure. Therefore, cloud computing can even allow you to experience the computing power of 10 trillion operations per second. With such powerful computing power, you can simulate nuclear explosions, predict climate change and market trends. Users access the data center through computers, notebooks,...
