Problems solved by technology

The current ADS-B mainly relies on GPS navigation signals as positioning signals. When an attacker interferes with or modifies the navigation signals, the aircraft may not be able to receive navigation signals, or may receive false navigation signals.

Embodiment Construction

[0093] 1. Invention realization

[0094] The invention uses the PBC (Pairing-based cryptography) library developed by Stanford University based on the C language on a computer equipped with a Windows 10 operating system, a hardware configuration of an intel-i3 3.8 GHz processor and 4 GB RAM to implement the algorithm.

[0095] PBC library is an open source, free and modifiable C language library. It can perform rapid prototyping of pair-based cryptosystems. It provides a highly abstract interface for the realization of bilinear mapping and shields complex mathematical details. Researchers can achieve this without even considering the knowledge of elliptic curves and number theory. Cryptosystem based on bilinear mapping.

[0096] There are 7 types of pairings in the PBC library: A, B, C, D, E, F and G. Common types of pairing parameters are shown in Table 3.

Abstract

The invention relates to the technical field of information security, in particular to a broadcast type automatic correlation monitoring system (ADS-B) message authentication scheme based on certificateless short signatures. Aiming at potential safety hazards of ADS-B, by utilizing the characteristics of low bandwidth and less available data bits, the invention provides the ADS-B message authentication method based on the certificateless short signature. Compared with the current similar methods, the signature length is reduced by 3 / 4, the overall performance is improved to a certain extent, and the signature periodical performance is improved by nearly 1 time. In addition, the method does not need to manage certificates, eliminates the problem of secret key hosting, and greatly reduces the burden of the system ADS-B. And the availability and the overall safety of the system are enhanced. In order to further analyze the performance of the authentication method, NS2 is used to simulatethe ADS-B network, and the result shows that on the premise of guaranteeing ADS-B data integrity, identity authentication and non-repudiation, the influence on the network is very small, and the minimum operation function standard specification of 1090ES is met.

Description

Technical field [0001] The invention relates to the technical field of information security, and is a broadcast type automatic correlation monitoring system (ADS-B) message authentication scheme based on certificateless short signature. Background technique [0002] In recent years, with the improvement of the economic level, the aviation industry has developed rapidly, and the number of aircraft has also increased. With the increase in the number of passengers and the demand for passenger transportation, the total number of commercial aircraft in various countries has increased significantly every year. Therefore, in the foreseeable future, the number of aircraft in the airspace will continue to increase, and the airspace will become more crowded, which will bring great challenges to the traditional Air Traffic Control (ATC) technology. [0003] 1. Security vulnerabilities in ADS-B system [0004] ADS-B is a technology developed in coordination between air and ground and an import...
