Abstract

The invention discloses a scheme for implementing two-way identity authentication between a user and cloud by applying a portable TPM (PTPM) and certificateless public key cryptography to a cloud environment, aiming at solving the security problems and deficiencies existing in identity authentication between the user and the cloud in a current cloud environment in a cloud computing mode. Comparedwith existing schemes, a new scheme has the following advantages: on the basis of realizing the uniqueness of user and cloud identities through the establishment of an identity management mechanism, firstly, the PTPM is adopted to ensure the security and credibility of a terminal platform and ensure the authenticity and correctness of authentication results between the cloud and the user, and moreover, the user is supported to use any terminal equipment to complete an identity authentication process with the cloud; secondly, the new scheme implements a 'password + key' two-factor authentication process based on a certificateless public key signature algorithm; and finally, the proposed scheme can significantly improve the computing efficiency of identity authentication between the user andthe cloud while ensuring the security of EUF-CMA.

Description

technical field

[0001] The invention belongs to the technical field of cloud computing applications, and in particular relates to a cloud-based two-factor authentication method based on PTPM and certificateless public key signature. Background technique

[0002] Cloud computing is an emerging service model that provides resources such as storage and computing based on the Internet. With the help of cloud services, enterprises, organizations and individual users can easily and quickly perform operations such as massive data computing and data storage and sharing. However, cloud service providers (CSPs) first need to authenticate the identities of enterprises, organizations and individual users who use cloud services to determine their correctness and legitimacy. Otherwise, users who have not applied for registration or purchased cloud services can use cloud services, which, on the one hand, will bring huge service response burdens and serious economic losses to CSPs. Loss o...
