摘要：

In modorn cryptography, post-quantum signature schemes become more preferable because they can remain secure even if the attackers can execute quantum computations. Many technologies used for security proof cannot be directly extended to quantum settings, especially in the case that the online oracles are quantum-accessible. In this talk, we give introduction and quantum security analysis on modern post-quantum signature schemes, such as the three candidates in the finalist of the NIST post-quantum standardization. In particular, we consider the security model where the adversary has the ability of querying in quantum superposition.
