Quantum homomorphic signature

摘要：

　　Quantum signature is an effective approach to identity authentication for single stream in quantum networks,but it is constrained in the crossing case of multiple streams.To solve this problem,we present a quantum homomorphic signature scheme to enhance the security of quantum networks.By entanglement swapping,this scheme can combine two quantum signatures and generate a new homomorphic signature.Analysis results show that the proposed signature scheme can effectively guarantee the security of secret key and verify the identity of different data sources in a quantum network.
