IDentity-based Password Authentication and Key Establishment (ID-PAKE) is an interesting trade-off between the security and efficiency, specially due to the removal of costly Public Key Infrastructure (PKI). However, we observe that previous PAKE schemes such as Beguinet et al. (ACNS 2023), Pan et al. (ASIACRYPT 2023) , Abdallah et al. (CRYPTO 2020) etc.
fail to achieve important security properties such as weak/strong Perfect Forward Secrecy …
