Quantum-message-oriented public-key encryption scheme beyond computational hypothesis
Min Liang, Li Yang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2012
We propose two definitions of quantum one-way transformation and quantum trapdoor one-way transformation beyond computational hypothesis, and give four examples. Then, we present a general way to construct a quantum public-key encryption scheme from a quantum one-way transformation and a quantum trapdoor oneway transformation, and give a concrete example which is quantum-message-oriented. The security of this kind of encryption schemes is based on the one-way property of quantum one-way transformation and quantum trapdoor one-way transformation, and this kind of schemes is information-theoretically secure.
