Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , the implementation steps of the present invention are as follows:

[0032] Step 1, build an agent-based authentication and key agreement system.

[0033] (1a) In the LTE network, the key generation center KGC and the home subscriber server HSS are assembled together through a physical connection, and a temporary connection between the home subscriber server HSS and the mobility management entity MME is generated through the network domain security mechanism NDS Session key to build a parameter transmission channel;

[0034] (1b) Between the LTE network and the machine type communication device MTCD, a proxy authorization channel is established between the gateway GW and the mobility management entity MME through the following process:

[0035] First, the gateway GW uses the device certificate stored by itself to complete the device authent...

Abstract

The invention discloses an agent-based machine type communication authentication and key agreement method, which mainly solves the problem of signaling congestion in the prior art. The implementation steps are: 1. Build an agent-based authentication and key agreement system; 2. The key generation center generates system parameters, and calculates and distributes the keys corresponding to the identity information of the mobile management entity, gateway, and machine-type communication device ; 3. The mobile management entity entrusts the signing authority; 4. Performs two-way authentication between the entrusted gateway and the MTC device; 5. The MTC device and the MME generate a session key. The present invention uses the gateway to complete the authentication and key agreement of the machine-type communication equipment in the LTE network through the proxy signature, which reduces the degree of signaling congestion caused by a large number of machine-type communication equipment accessing the network at the same time, and can be widely used in future LTE in the network.

Description

technical field [0001] The present invention belongs to the field of communication technology, and further relates to an authentication and key negotiation method of a machine type communication MTC in a long-term evolution LTE network, which can be used in a scene where a large number of MTC devices access the LTE network, and is used to solve the problem of signaling congestion , overcome the difficulty of resource exhaustion of the group leader, reduce the signaling load of the core network, and complete the key negotiation function. Background technique [0002] As an important means of communication in future mobile communication, MTC has attracted more and more attention. In an LTE network, realizing low energy consumption of devices and simultaneous transmission of multiple devices is a key issue in obtaining MTC applications. According to the existing 3GPP standard, when a large number of MTC devices are connected to the network at the same time, each MTC device nee...
