Abstract: Cloud computing is a new information technology. It is the product of the scientific and technological development of the times and plays an important role in the development of this country. In order to effectively solve the security problem of cloud computing data access, an identity-based privacy protection algorithm for cloud computing is proposed. The user information is stored in the cloud server at the registration stage, and the user identity is verified by signature when the information is obtained. The strong forward secure signature scheme can ensure that the signature is both forward secure and backward secure. At present, most signature schemes based on lattice focus on forward security. Therefore, this article constructs a strong forward secure signature scheme based on lattice and applies this signature scheme to cloud user authentication to ensure security.
