Two Kinds of Method to Construct Oblivious Transfer Protocols
Huang Gen-xun
As a fundamental cryptology protocol,oblivious transfer is applied abroad in practice.The methods to construct the protocol are divided into two kinds,direct and indirect.With the help of idea of the representation of integer in base t and the DDH assumption,it proposes a kind of indirect method to construct the protocol with lower computation complexity based on Naor-Pinkas′s scheme,moreover,another kind of direct method is put forward in terms of the some public cryptosystems with homomorphism.
