This paper designs the simulation processes of QKD on a classical computer,taking E91 protocol as an example, and analyzes the simulation results in three cases: the channel is ideal,the channel is noisy, and the eavesdropper exists. The security of protocol is also shown. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1503-0304
