Revisiting Anonymity in Post-quantum Public Key Encryption
摘要
This paper revisits the anonymity of post-quantum public key encryption in the presence of CCA attacks (ANO-CCA). Specifically, we demonstrate the anonymity of key encapsulation mechanisms (KEMs) obtained from Fujisaki-Okamoto (FO) transformations in the quantum random oracle model (QROM) and the anonymity of hybrid encryption via the KEM-DEM paradigm in both implicit and explicit cases. Our results are presented as follows:
