Abstract: In this paper, we design an ID-based M-server quantum password-authenticated key exchange scheme, where the client computes a strong key from its password and splits the key into m portions, and then encrypts them and sends them to m servers to be used as the basis for encryption and decryption in the subsequent key exchange process. The adoption of multiple servers can effectively prevent third-party attacks on the server and ensure the security of the key information, which is just like a complex secret sharing mechanism in traditional computational cryptography, for example, secret sharing (m, n) threshold scheme, but our new quantum fusion technology to realise the secret sharing mechanism is more efficient and simpler. Finally, through analysis, our scheme can meet most of the security requirements and perform well. It is feasible to implement the protocol under the existing quantum technology.
