The invention discloses an enhanced binding based anti-attack method of an IPv6 mobile terminal. The method comprises that input user information is obtained, and an authentication request is sent according to the user information; an access inquiry message returned according to the authentication request is received; a response message is generated according to the access inquiry message and sent, so that a server authenticates the user information according to the response message; if authentication succeeds, an access acceptance message returned according to the response message is received; and a shared secret key contained in the access acceptance message is extracted, a binding update message or a binding confirmation message is encrypted according to a preset updating rule, and safety attack is resisted. The method provided by the invention has the following advantages that (1) safety guarantee is provided for local registration and communication code registration of the IPv6 mobile terminal, and the safety of IPv6 mobile terminal network is improved; (2) it is not required to relay on the IPSec of high cost, low efficiency and tedious configuration; (3) both computational complexity and information content are low; and (4) the efficiency is high.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to an enhanced binding-based IPv6 mobile terminal anti-attack method. Background technique [0002] With the rapid development of Internet applications, the existing IPv4 addresses are almost exhausted. The new generation of Internet with the IPv6 protocol as the core provides unlimited address space and provides faster, higher and stronger services. However, with the increase of IPv6 applications, especially the explosive growth of IPv6 applications dominated by smart phones, new security issues for IPv6 mobile terminals are constantly emerging, such as IPv6 address configuration, neighbor discovery, extended header issues, etc. , bringing huge losses to society and individuals. [0003] During the home registration and communication node registration process of IPv6 mobile terminals, attackers can disrupt normal communication by sending false binding updates, or redirect da...
