Abstract With the development of power communication networks, the demand of information security involved in power network services also increases. Traditional secure communication technology have not been able to guarantee the security of the information transmitted in absolute security. This paper focuses on the problem of secure transmission of power communication networks, and proposes a suitable quantum secure communication technology scheme to ensure the key rate of the long-distance quantum secure communication and the security of the power communication network.

Recently, great progress has been achieved worldly in quantum secure communication system experiments and application study. Related research enters into a key period of practical realization, though the hot issue about its practicability is still on. Quantum secure communication, which has unique advantages in eavesdropping checking, identity authentication and keys online distributing, will lead a great revolution in the field of secure communication In this paper, we firstly introduce the statues, basic theory and characteristic of quantum Secure communication. Then, we study on the trends, prospect and countermeasures of quantum secure communication in deep.

Combining the idea of quantum secure communication and quantum homomorphic signature, we propose a quantum secure communication protocol with signature via EPR pairs, in which the identities of the sender and the recipient could be certified and the integrity of the message transmitted is guaranteed according to their signatures. Comparing with the previous quantum secure communication scheme without signature, our protocol is not only feasible in practice but also can effectively guarantee the reliability and security of the quantum communication. The security of the protocol is analyzed.
