Verifiable Oblivious Transfer Protocol
Oblivious transfer protocol, which is an important and useful cryptographic protocol, has been widely applied in cryptographic field, especially, in construction of secure multiparty computation protocol. However, all existed oblivious transfer protocols have two drawbacks for security requirement: 1) the receiver does not know whether message received is one of messages held by the sender; 2) the sender does not know whether message received by the receiver is one of messages designated by himself. In order to conquer these drawbacks, we firstly propose the notion of verifiable oblivious transfer protocol, and firstly construct it by using proof protocol of knowledge, i.e., ∑-protocol, as main tool.
