Example Embodiment

[0085] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0086] Such as figure 1 As shown, the D2D communication two-way authentication method based on physical channel information includes the following steps:

[0087] S1. Pre-set a shared key K(k) for terminal A and terminal B for D2D communication;

[0088] S2. Terminal A makes a communication request to terminal B;

[0089] S3. Terminal B sends a random authentication sequence s to terminal A 1 (t);

[0090] S4. Authentication sequence s 1 (t) Transform to sequence r after passing through the channel 1 (n), terminal A receives sequence r 1 After (n), using the pre-shared key K(k), the sequence r 1 (n) Perform processing to obtain the authentication response sequence s' 1 (t), send it to terminal B;

[0091] S5. Authentication response sequence s' 1 (t) Transform to...

Abstract

The invention discloses a D2D communication mutual authentication method based on physical channel information. Initial authentication based on physical channel information can be conducted as long as one communication secret key is stored, and complex upper-level authentication is no longer needed, so the calculating complexity of initial authentication is greatly reduced. The D2D communication initial authentication step is moved to a terminal, and information is estimated by means of channels during authentication, so the complexity of initial authentication is reduced and the authentication time delay is reduced. After initial authentication, both D2D communication parties carry out information packet authentication based on physical channels on information packets received each time to prevent missing information packet authentication during D2D communication. In this way, the privacy of a user is protected, and an attacker is prevented from maliciously tampering with information packets.

Description

technical field [0001] The invention relates to a D2D communication bidirectional authentication method based on physical channel information. Background technique [0002] The explosive growth of wireless mobile users and data has brought great challenges to the capacity of cellular network systems. Device-to-Device (D2D) communication technology improves spectrum utilization by improving space utilization, and makes mobile communication more direct and efficient in some scenarios, which not only relieves the pressure on base stations, but also reduces end-to-end It also increases the bit rate, reduces the battery power consumption of the mobile terminal, and greatly improves the user experience. [0003] However, due to the openness of the wireless communication system and the characteristics of the D2D communication system itself, users in the system may become targets of malicious users, such as eavesdropping on data, disseminating wrong information, or violating privac...
