Quantum security analysis of a lattice-based oblivious transfer protocol
Because of the concise functionality of oblivious transfer (OT) protocols, they have been widely used as building blocks in secure multiparty computation and high-level protocols. The security of OT protocols ...

Efficient quantum dialogue using entangled states and entanglement swap** without information leakage
We propose a novel quantum dialogue protocol by using the generalized Bell states and entanglement swap**. In the protocol, a sequence of ordered two-qutrit entangled states acts as quantum information chann...

Efficient identity-based signature over NTRU lattice
Identity-based signature has become an important technique for lightweight authentication as soon as it was proposed in 1984. Thereafter, identity-based signature schemes based on the integer factorization pro...

Efficient Quantum Dialogue by Using the Two-Qutrit Entangled States Without Information Leakage
A quantum dialogue protocol, based on the two-qutrit entangled states is proposed in this paper. In this protocol, the security of communication is ensured by the secret transmitting order of qutrits. Two legi...

CCA2 secure biometric identity based encryption with constant-size ciphertext
We propose a new biometric identity based encryption scheme (Bio-IBE), in which user biometric information is used to generate the public key with a fuzzy extractor. This is the first Bio-IBE scheme that achie...
