[en] We revisit the concept of public key encryption with delegated
keyword search (PKEDS), a concept proposed by Ibraimi et al. A PKEDS
scheme allows a receiver to authorize a third-party server to search in two
ways: either according to a message chosen by the server itself or according
to a trapdoor sent by the receiver.We first show some observations on the
primitive formulation and the proposed PKEDS scheme by Ibraimi et al.
and point out that the single-server setting may limit the application of this
primitive. We then extend the concept to the multiple-server setting and
present a new security model. We finally propose a new PKEDS scheme,
which is proven secure, and compare it with that by Ibraimi et al.
