Zhou Hong-yuan · Journal of Shenyang Aerospace University · 2011
To improve the communication security of TTC network,this paper presents an application model of quantum key distribution technology in distributed aerospace TTC network with the method of delay tolerant network.It sets up the quantum key distribution system between ground station and spacecraft,and uses spacecraft to encrypt the key and transmit it as an agency to make two ground stations get shared key safely.The shared key is used to encrypt the information in public channel to keep it safe.In the process of transmitting shared key,in view of the characteristic of delay tolerant network,this paper has improved the epidemic routing algorithm and simulated it.The result shows that the efficiency of epidemic routing algorithm after improved has increased substantially.
