Deniable encryption (Canetti et al. CRYPTO ’97) is an intriguing primitive, which provides security guarantee against coercion by allowing a sender to convincingly open the ciphertext into a fake message. Despite the notable result by Sahai and Waters STOC ’14 and other efforts in functionality extension, all the deniable public key encryption (DPKE) schemes suffer from intolerable overhead due to the heavy …
