With the rapid development of 6G and the widespread application of cloud computing technologies, system security issues in distributed cloud computing have become increasingly important. In the cloud computing environment, ensuring user anonymity, legitimate device access, communication security, and the efficiency of the authentication process has become a critical challenge that must be urgently addressed. To tackle this challenge, this paper proposes an anonymous, secure, and efficient authentication scheme for 6G cloud computing. The scheme supports both user authentication and device access authentication. By combining the characteristics of Chebyshev chaotic mapping and a multi-factor authentication mechanism, the proposed scheme ensures secure authentication of user identities and access devices and guarantees the security of subsequent session keys, thereby effectively safeguarding communication security between authorized users, legitimate devices, and cloud servers. Moreover, the scheme integrates Physical Unclonable Function (PUF) on the device side, leveraging its unique hardware features to provide strong identity recognition and resistance to physical attacks, thus improving the system's authentication efficiency. Performance comparisons show that the proposed scheme reduces the computational overhead by an average of 30.45% and the communication overhead by an average of 16.32% compared to the baseline scheme.
