| With the rapid development of the Internet, the traditional IPv4has beenshowing increasing defect. Now IPv6has become the mainstream ofcontemporary research, with the rapid development of wireless communicationtechnology as well as the portable terminal, the traditional fixed networktechnology can not meet our demand for the Internet. IETF RFC haveformulated the document to the provisions Mobile IPv6mobility managementstandard.Although mobility has brought great convenience to the people, but tobring convenience, while a new management agreement also brings securitythreats. Currently RFC3775requirement to use IPSec to secure communicationmessages between the mobile node and home agent,IPSec required a static IPaddress mapping associated with security, due to the uncertainty of thecommunication peer, the provisions of the IETF working group the RRmechanism to protect mobile nodes with communication end binding registration packets, but the RR mechanismis still not mature enough, can notplay a role in the threat to the home link, this article is primarily for the mobilenode to the registration of the communication on the end of a security,easy-protection program.For the The mobile node switching process is mainly follows the RFC3775document, but the mobile terminal to bring convenience, but also has its weakcapacity, poor battery life shortcomings. Specified in RFC3775mobile nodeneeds to be done with higher communication overhead peer key negotiation andbinding registration also need to complete the work with the home agent, whichbear a greater burden of the mobile nodes. This paper mainly about the lesscomputing capacity of the mobile node the mobile suitable weak computingcapacity of the mobile terminal the mobile switching scheme, to reduce themobile node reduces the computational overhead of a mobile terminal handoffdelay and improve the safety of the switching process.This paper first describes the operation of Mobile IPv6managementagreement function node needs to be done, then a detailed analysis of the majorsecurity threats about mobile nodes in the handover process, and introduced the existing IPSec with return routability mechanism.Chapter4present a improvedMobile IPv6binding registration program, and aim at the lack of mechanismsfor RR put forward a double PKG of identity-based key agreement mechanism.In this scheme greatly reduces the computational overhead of the mobile nodeand mobile switching delay, reducing the signaling overhead on thecommunication line, and preferably to protect the safety of the switching process.In this paper, double PKG of identity-based key agreement mechanismeffectively prevent the original identity-based key agreement mechanism ofPKG leakage key threat. Finally, the experiment proved that this program isbetter in reducing the handoff delay when the mobile node with the increase intransmission delay. |
