Abstract

Background: Aiming at the problem of user information security authentication in cloud manufacturing, a user information security authentication model is proposed. The model is introduced in detail.

Methods: In the security authentication model, the point set topology group fractal transformation algorithm is combined with the biometric identification technology to acquire the user biometric information to generate the secret key. Combined with the AES (Advanced Encryption Standard) encryption algorithm, the user biometric information is encrypted.

Result: It provides a stronger guarantee for the user's security certification. We revised all patents relating to pharmaceutical formulations of applicability in authentication of user information in cloud manufacturing.

Conclusion: Experiments show that the research has credibility and practicability, which improves the overall security performance of cloud manufacturing user information authentication and access.

Keywords: Cloud manufacturing, security authentication, biometrics, point set topological group, fractal changing algorithm, AES encryption algorithm.
