Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
The first embodiment.
As shown in fig. 1-2, the present embodiment provides the following technical solutions: the Key distribution system based on wireless cascade comprises Public Key Authority, an initiator A and a Pesponder B;
public Key Authority, Initialator and Pesponder.
The Request time1 is used as a primary Request between Public Key Authority and the Initiator A, and the KER Request time1 is used as a secondary Request between the Initiator A and the Public Key Authority.
The response from Initialator A to Pesponder B was three times with EKU Ida N1, and the response from Pesponder B to Initialator A was four times with EKU N1N 2.
Request time2 is used as a fifth Request between the Pesponder B and Public Key Authority, and EKR Request time2 is used as a sixth Request between the Public Key Authority and the Pesponder B.
Public Key Authority responds seven times to Pesponder B with EKU N2 through Initialator.
Pc3 and Pc4 communicate in LAN a through Router 1, Pc1 and Pc2 communicate in LAN B through Router 2, LAN a and LAN B communicate with each other through Pc5, and Pc5 establishes wireless connection between LAN a and LAN B through a key distribution system;
the different wireless networks in fig. 2 are directly connected through the host, which aims to reduce redundancy in wireless transmission, and such deployment can fundamentally reduce the shielding effect of buildings on channels, so that the wireless networks can not be limited by the strength of signals, and from the perspective of users, users can obtain response at the fastest speed to improve efficiency.
Example two
As shown in fig. 3, when the distance is fixed, the host may receive information through a cascade Port (cascade Port) and send information through a universal Port (normal Port).
EXAMPLE III
As shown in fig. 4, at any long distance, Pc a needs to establish connection with Pc B, but since the channels too far away cannot be directly connected, the connection can be established indirectly through Pc1\ Pc2, Pc1\ Pc3 by using a key distribution system, that is, Pc1, Pc2, and Pc3 as bridges, thereby achieving the desired effect.
Although embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are exemplary and not to be construed as limiting the present invention, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
