Stochastic routing in quantum cryptography communication network based on cognitive resources
Min Li, Dongxiao Quan, Changhua Zhu · 2016
In quantum cryptography network routing selection is an important task for performing end-to-end key agreement. In the paper, we propose a stochastic routing algorithm based on distance vector and residual key bits. The main idea is that after all the shortest paths have been obtained, the communication key bits can be transmitted randomly in any path with enough residual key bits. Simulation results show that under stochastic routing algorithm a higher security level can be provided than the one under traditional routing algorithm, e.g. Routing Information Protocol (RIP), in quantum cryptography network.
