A public cloud network includes at least one private cloud server (108) and at least one smart client device (106-111) in communication therewith. The private cloud server and at least one smart client device have a client server relationship. The private cloud server and client have respective first and second message boxes (e-mail, SMS) located in the public network. Session based message information is passed in e-mails or SMS messages between the server and client device via the first and second message boxes in a secure manner. The session based information is authenticated by the server and client. The client device and private cloud server can then communicate with each other after the session based information is authenticated. The method allows the client to traverse a firewall in front of the private cloud server. |
