Description
Technical field
The present invention relates to security system technical field, particularly relate to a kind of force safe cloud terminal system and force peace
Full method.
Background technology
SSH is a kind of procotol, the encrypted login between computer.If a user is from local computer,
Using another remote computer of SSH protocol entry, we are just it is believed that this login is safe, even if being cut by midway
Obtaining, password also will not be revealed.
SSH software kit is made up of with client two parts server end.Server end is mainly arranged on controlled terminal, i.e.
We need the object remotely managed.And client is just mounted on the main frame of operation side.SSH uses based on key
Safety certification.Under this authentication, need to rely on key to be authenticated.Now, user needs to create one for oneself
To key.User will be by the way of other safety, PKI side on the server needing remotely management.When manager connects
The when of on SSH server, client can send request to server, it is desirable to it utilizes the key of client to carry out safety
Certification.After server receives the request of client, the PKI that you will be utilized to issue him in advance compares, distinguishes.As wanted two
If individual key agreement, server is just addressed inquires to public key encryption and sends it to client software.Client software receives
After the inquiry of server, it is possible to utilize private key to be decrypted and send the result to server.
Potential safety hazard, the double secret key of SSH can copy, and SSH private key is put on illegal terminal still can be with Connection Service device
The most dangerous.
