Abstract

Abstract: Recently, a new framework, called secure server-designation public key encryption with keyword search (SPEKS), was proposed by Chen to withstand online keyword guessing attack. Moreover, Chen proposed a concrete scheme (IBE, TE)-2-SPEKS and proved that their scheme meets trapdoor indistinguishability. In this comment, we point out that the trapdoor, in fact, can be distinguished by the adversary.
