Problems solved by technology

Next, packets between MN and CN are to contain TMI in place of current home address in Home Address option and Type 2 Routing header, so eavesdroppers cannot identify packets belonging to a particular node
But this method has the following defects: 1. The first 16 bits are fixed, so an attacker can easily identify the TMI; 2. TMI is a substitute for the home address, so the update of the TMI requires the same security as the update of the home address. Then the periodically updated TMI will cause frequent execution of RRP (Routable Reachable Return Process); 3. The serial number of the BU message is incremented, so you can continue to track it

Embodiment Construction

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] The basic idea of ​​the method for hiding the home address of the IPv6 mobile node of the present invention is that after the mobile node accesses the network link at the current access place and obtains the care-of address, the mobile node replaces the home address with a privacy identifier (PID), and will contain The binding update message of the mapping relationship between the PID and the care-of address is sent to the home agent and the correspondent node. During the RRP (return path reachable process) process between the mobile node, the home agent and the correspondent node, there are also BU binding In the fixed update process, both HoTI and HoT messages use the address and PID of the home agent to communicate, thus hiding the home address of the mobile node.

[0024] In order to keep the communication smooth during the three-...

Abstract

This invention discloses a communication method for MIPv6 mobile nodes including: a mobile node accesses network at the access place and gets a new delivery address to be used to compute PID, and the mobile node uses the PID instead of its hometown address and binds it with the delivery address as the updated messages to be sent to the hometown proxy and communication nodes, which utilizes the PID to resume the hometown address of the mobile node.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a communication method of an MIPv6 mobile node. Background technique [0002] The development direction of the mobile IPv6 network is to evolve into a diversified seamless broadband access network. Various wired and wireless access methods need to provide universal mobility for user service experience, so that users can enjoy unified service features anytime, anywhere. When the mobile node (MN) is in the home network segment, it communicates with the correspondent node (CN) according to the traditional routing technology, without the intervention of Mobile IPv6. When the mobile node moves to the foreign link, the home address of the mobile node remains unchanged, and a temporary IP address (ie, the care-of address) is obtained at the same time. The mobile node informs the home agent (HA) of the binding message between the home address and the care-of address...
