Embodiment Construction

[0078] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0079] The steps of a message transmission method based on a link management protocol security association provided by an embodiment of the present invention are as follows:

[0080] Step 101, configure LMP security association;

[0081] The LMP security association includes the following parameters:

[0082] (1) The key identifier KeyID is used to uniquely identify a security association;

[0083] (2) Key Key, used to encrypt data;

[0084] (3) a key algorithm algorithm, which is used to encrypt the LMP message using the key Key to generate the content of the authentication data cell in the LMP authentication object;

[0085] (4) Sequence number, used to provide anti-replay protection service.

[0086] Both parties in the message ex...

Abstract

The invention discloses a message transmission method and device based on a link management protocol (LMP) security alliance (SA), and aims to solve the problem that IPSec (Internet Protocol Security) is not suitable for the LMP. The technical scheme is that: the LMP security alliance is configured and an LMP authentication object is added for carrying out authentication of an LMP message; when the LMP message is sent out, the LMP authentication object is generated based on a local LMP security alliance, and the LMP message carries the generated LMP authentication object; and when the LMP message is received, the LMP authentication object is extracted from the LMP message, the local LMP security alliance corresponding to the extracted LMP authentication object is acquired, and the received LMP message is authenticated based on the local LMP security alliance and the extracted LMP authentication object. According to the invention, the integrity and confidentiality of the LMP message are guaranteed, and the replay-attack-resistant capability is realized.

Description

technical field [0001] The invention relates to routing security technology in a communication network, in particular to a message transmission method and device based on a Link Management Protocol (Link Management Protocol, LMP) security association. Background technique [0002] LMP uses the IP security protocol IPSec as a security mechanism, which is described in detail as follows: [0003] 1. The LMP implementation using the IPSec protocol must be able to support the manual key mode. Manual key mode provides an easy way to establish IPsec functionality. But the manual key mode cannot effectively support replay attack protection and automatic key reset. [0004] 2. IPsec Encapsulating Security Payload (IPsec ESP) supports authentication in channel mode. [0005] 3. Its implementation must support an authenticated key exchange protocol. [0006] 4. Implementations MUST use the IPsec Domain of Interpretation DOI [RFC2407]. [0007] 5. For the IKE protocol (Internet Key...
