MPTCP METHOD CLOUD SERVER AND HOST FOR SECURE AND LIGHTWEIGHT SUBFLOW ESTABLISHMENT IN MPTCP

摘要

The present invention relates to a subflow secure connection method of MPTCP and a cloud server and a host using the same, wherein a) a handshake is performed between a network address of the cloud server and a network address of a host to perform a handshake in the initial connection state, the cloud transmitting an acknowledgment request message to the host when receiving an Address Advertisement (ADD_ADDR2) option from the server; and b) performing a subflow connection when an acknowledgment message (ACK) is received from the host, wherein the acknowledgment message is the network address possessed by the host and the network address of the acknowledgment request message. It may be the way it is created.
