Security of NEQR Quantum Image by Using Quantum Fourier Transform with Blind Trent

Mustafa Engin Şahin, Murat İhsan Yılmaz

In this study, the security of Novel Enhanced Quantum Representation (NEQR) of quantum images are suggested by using the Quantum Fourier Transform (QFT) with blind trent. In the protocol, QFT and keys are used to share signature with recipients. So all members know only their signature information which are encrypted output of the QFT. This improves the security of the protocol. In addition, the security of the protocol is provided by using reorder QFT output qubits with permutation of the blind trent. The security analysis expresses security of the transfer of the image with effective secret key usage.

Timed-release oblivious transfer

Lingling Xu, Fangguo Zhang, Shaohua Tang

We study a variant of oblivious transfer, we called timed-release oblivious transfer that permits a sender to restrict when each receiver may open his chosen messages, without learning anything about the receiver's message choices. To achieve this functionality, we import a time server into the protocol that broadcasts a time token periodically and needs neither to interact with the sender nor the receiver. In our generic construction for the protocol, a primitive called verifiably ID-based encrypted blind signature is introduced as a basic building block. We also present a concrete scheme for the protocol's generic construction. Copyright © 2013 John Wiley & Sons, Ltd.
