Embodiment Construction

[0028] The present invention adds a 1-bit flag——S—in the MIPv6 signaling message, which is used to indicate that the signaling message includes the option of carrying the AAAA record update key. The extended binding update (Binding Upate, BU) message format is as follows figure 1 shown.

[0029] When the S flag is 1, it indicates that the BU message contains the option to carry the AAAA record update key.

[0030] Key option defined in the present invention——DNSKEY mobile option format such as figure 2 shown.

[0031] The rules for using this option are as follows:

[0032] 1) If the BU message contains both the DNS Update move option and the DNSKEY move option defined in RFC5026, it indicates that the HA needs to perform secure dynamic updates for the MN's AAAA and PTR records;

[0033] 2) If the MN only includes the DNS Update mobile option defined in RFC5026 in the BU but does not have the DNSKEY mobile option, it means that the MN defaults to the HA to perform dynamic...

Abstract

The invention discloses a network-based DNS security updating method in MIPv6. The method comprises the following steps: adding new items with key information for AAAA record updating into Binding Update (BU) of MIPv6, and providing service regulations of the items; transmitting the AAAA updating key of MN to HA through MIPv6 signalling, thereby ensuring the security of the AAAA record and the PTR record updating. By adopting the method, HA takes the duty of DNS updating operation of MN, so that the efficiency of updating operation is improved, dynamic DNS updating of large-scale nodes is supported, and in addition, the operation process of the method is compatible with updating operation defined in later RFC5026.

Description

technical field [0001] The invention belongs to the domain name system (Domain Name System, DNS) technical field, in particular to a network-based DNS security update method in MIPv6. Background technique [0002] Domain Name System (DNS), as the core basic service of the Internet, provides the most basic functional support for most Internet applications. [0003] However, under the growing trend of mobile Internet development, how to solve the dynamic updating of DNS information of a mobile node (Mobile Node, MN) is an important issue in the field of mobile Internet. For this reason, the Internet Engineering Task Force (IETF) proposed the Dynamic Domain Name System (Dynamic Domain Name System, DDNS) protocol—RFC2136—for hosts whose IP addresses change. DDNS maps the user's dynamic IP address to a fixed IP address. On the domain name server of the domain name server, every time the user connects to the network, the client program will transmit the dynamic IP address of the ...
