Embodiment 1

[0059] Embodiment 1 simulates the relationship between user connection probability and base station density, and compares the present invention with the maximum security capacity access strategy and the strategy in document [1].

[0060] pass figure 2 It can be found that the connection performance of the user brought by the access strategy proposed by the present invention can be well described by the theoretical formula in the present invention. The connection performance brought by the proposed strategy can approach the maximum security capacity access strategy, which is better than the strategy in literature [8]. At the same time, with the increase of base station density, the connection probability of users decreases, but the decreasing trend is slow.

Embodiment 2

[0061] The second embodiment simulates the relationship between the user's security probability and the base station density, and compares the present invention with the maximum security capacity access strategy and the strategy in document [8].

[0062] pass image 3 It can be found that the security performance of the user brought by the access strategy proposed in the present invention can be well described by the theoretical formula in the present invention. The security performance brought by the proposed strategy can approach the maximum security capacity access strategy, which is better than the strategy in literature [8]. At the same time, with the increase of base station density, the security probability of users is significantly improved.

Abstract

The invention discloses a security access strategy in a heterogeneous network with maximum security capacity, belongs to an information security technology in the field of wireless communication, relates to a physical layer security technology, and aims to enable a user to obtain better security performance by accessing a base station with the maximum security capacity on the premise that the basestation can acquire position information of a potential eavesdropper and the user. In consideration of a large amount of in-band interference possibly existing in a heterogeneous network, a simple and practical access strategy is designed, and base station access is carried out based on the maximum safety capacity criterion, so that the safety performance which can be obtained by a user is improved, and the safety performance of the user is close to the safety performance of the user under the maximum safety capacity criterion.

Description

technical field [0001] The invention belongs to information security technology in the field of wireless communication, relates to physical layer security technology, and is a security access strategy in a heterogeneous network with maximum security capacity. Background technique [0002] The rapid development of wireless communication technology has brought great convenience to people's life, but due to its inherent openness, wireless communication is vulnerable to outside eavesdropping, which poses a serious threat to communication security. How to prevent important information from illegal eavesdropping and ensure the security of communication is one of the hot issues in the field of communication research. [0003] There are two main types of current information security technology (document [1]): one is the traditional security strategy based on cryptography, and the other is the security strategy based on physical layer security technology. Traditional security strate...
