Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] figure 1 is a flowchart of a message interaction method according to an embodiment of the present invention, such as figure 1 As shown, the following steps S102 to S104 are included.

[0031] Step S102, using extended PIM protocol message to perform authentication negotiation.

[0032] Step S104, using the authentication data corresponding to the authentication negotiation to exchange messages.

[0033] In related technologies, IPSec services need to be configured in advance between all DRs and all RPs that may exchange packets, which will greatly increase the service burden of RPs. In the embodiment of the present invention, the authentication negotiation process is attached to the ...

Abstract

The invention discloses a message interaction method and device. The method includes: using extended PIM protocol messages to carry out authentication negotiation; using data corresponding to the authentication negotiation to carry out message interaction. The present invention can solve the problem in the related art that IPSec services need to be configured in advance between all DRs and all RPs that may exchange messages, thereby greatly increasing the service burden of RPs, and can eliminate the extra communication caused by using the IPSec method overhead.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for message interaction. Background technique [0002] Currently, PIM-SM is a recognized standard for intra-domain multicast. With the development of networks and multicast services, its security and reliability have drawn more and more public attention. The existing PIM-SM security policy mainly provides data integrity and data source identity authentication of protocol messages through IPSec. [0003] In related technologies, IPSec needs to be configured with an SA and an SPI for packets (such as Hello, Join / Prune, and Assert) of this link. For example, for registration messages, RFC4601 recommends that all PIM routers in the domain use the same authentication algorithm and parameters, including all DRs and all RPs. [0004] It can be seen that the configuration of IPSec needs to be aware of the networking at the sending and receiving ends of the packet, ...
