Method for construction of a high-security private group network

A method for construction of a high-security private group network based on operating system level virtualization for construction of a virtual private network and comprising steps as follows:

• step 1:
• a first user machine is electrically connected with a first private communication box and dependent upon specific authentication to join a first self-configuration peer-to-peer virtual private network constructed by the first private communication box using operating system level virtualization;
• step 2:
• a second user machine is electrically connected with a second private communication box and dependent upon specific authentication to join the first self-configuration peer-to-peer virtual private network constructed by the second private communication box using operating system level virtualization;
• step 3:
• packets are transmitted between the first user machine and the second user machine through the first self-configuration peer-to-peer virtual private network.
