Dear editor, We will introduce the notion of chameleon All-But-One Extractable Hash Proof (ABO-EHP) system. It is a special kind of ABO-EHP [1] with a tag space T that comprises two branches, denoted by TA× TB. Specifically, the tag space contains a subset S⊂ T and satisfies the so-called chameleon property. That is, for any a∈ TA, there is a unique and special b∈ TB (computed via a trapdoor) making (a, b)∈ S. The chameleon property allows us to construct public-key encryption (PKE) schemes from chameleon ABO-EHP systems directly, not relying on hybrid encryption mechanism. When encrypting short messages, eg, a PIN number, the direct construction in some sense is more efficient than the hybrid encryption schemes of [1–3] under the computational Diffie-Hellman (CDH) assumption. In the following, we first give a formal definition of chameleon ABO-EHP system. Then, we show how to construct a chosen-ciphertext secure (CCA) PKE scheme from a chameleon ABOEHP system. Finally, we present instantiations of chameleon ABO-EHP system for constructing efficient CCA-secure PKE schemes. Chameleon ABO-EHP system. First, we briefly recall the definition of binary relations that will be used in the chameleon ABO-EHP system.
