Oblivious Transfer Based on Key Exchange
نویسنده
چکیده
Key-exchange protocols have been overlooked as a possible means for implementing oblivious transfer (OT). In this article, we present protocols for mutual exchange of secrets, 1-out-of-2 OT and coin-flipping similar to the Diffie-Hellman protocol using the idea of obliviously exchanging encryption keys. Since the Diffie-Hellman scheme is widely used, our protocol may provide a useful alternative to the conventional methods for implementation of oblivious transfer and a useful primitive in building larger cryptographic schemes.

A new efficient k-out-of-n Oblivious Transfer protocol
This paper presents a new efficient protocol for k-out-of-n oblivious transfer which is a generalization of Parakh's 1-out-of-2 oblivious transfer protocol based on Diffie-Hellman key exchange. In the proposed protocol, the parties involved generate Diffie-Hellman keys obliviously and then use them for oblivious transfer of secrets.
متن کاملProtocols for Kak's Cubic Cipher and Diffie-Hellman Based Asymmetric Oblivious Key Exchange
This paper presents protocol for Kak’s cubic transformation and proposes a modification to DiffieHellman key exchange protocol in order to achieve asymmetric oblivious exchange of keys. The cubic transformation may be used to develop a cryptosystem that is more efficient than Rabin’s cryptosystem. The oblivious key exchange has applications in mutual exchange of secrets and m -out-ofn oblivious...
متن کاملEfficient Password Authenticated Key Exchange via Oblivious Transfer
We present a new framework for constructing efficient password authenticated key exchange (PAKE) protocols based on oblivious transfer (OT). Using this framework, we obtain: – an efficient and simple UC-secure PAKE protocol that is secure against adaptive corruptions without erasures. – efficient and simple PAKE protocols under the Computational DiffieHellman (CDH) assumption and the hardness o...
متن کاملA Novel Unconditionally Secure Oblivious Polynomial Evaluation Protocol
Oblivious polynomial evaluation is a protocol involving two parties, a sender whose input is a polynomial P , and a receiver whose input is a value x. At the end of the protocol, the receiver learns P (x) and nothing more about P , while the sender remains oblivious of both x and P (x). It is used as a primitive in many applications including protocols for private comparison of data, for mutual...
متن کاملProtocols for Authenticated Oblivious Transfer
Oblivious transfer (OT) is a basic building block in many cryptographic protocols. In this paper, we exploit some well-known authenticated Diffie-Hellman-based key exchange protocols to build three authenticated 1-out-of-2 oblivious transfers. We show that our proposed protocols are secure in the semi-honest model. We also compare our schemes with three similar 1-out-of-2 OT protocols and show ...
