Secure searchable public key encryption scheme against keyword guessing attacks
Hyun Sook Rhee, Willy Susilo, Hyun‐Jeong Kim · IEICE Electronics Express · 2009
Byun et al. firstly proposed off-line keyword guessing (KG) attacks and proved that some searchable public key encryption (PEKS) schemes are insecure against these attacks.They supposed an open problem on how to construct PEKS schemes secure against keyword guessing attacks.In this letter, we answer this question affirmatively.
