Oblivious transfer protocol is an important primitive in modern cryptography. Since its introduction, the subject has attracted a lot of attentions and has become the basis for realizing a broad class of cryptographic protocols, such as secret key exchange, contract signing, secure function evaluation, oblivious keyword search, etc. This work describes protocols for proxy oblivious transfer, in which the role of the sender is divided between two proxies, and a receiver (chooser) must contact one proxy in order to run the oblivious transfer protocol and another for some extra information. This proxy oblivious transfer protocol provides a method for the sender to delegate a proxy to transfer one of his messages to a receiver on behalf of him. The proxy oblivious transfer protocol has the same security properties as the oblivious transfer protocol using in our protocol.
