A certificateless broadcast signcryption method without bilinear pairing for uaanet

Abstract

The invention discloses a non-certificate-free bilinear pairing-free broadcast signcryption method suitable for UAANET, including the non-certificate-free bilinear pairing-free broadcast signcryption CBS and the certificate-free bilinear pairing-free broadcast signcryption CBDS. Utilizing CBS and CBDS technology to realize secure data transmission and authentication can quickly transmit encrypted communication information on the UAV wireless ad hoc network, and at the same time complete broadcast encryption of communication information and identity authentication. The present invention proposes a certificateless broadcast signcryption method without bilinear pairing. The certificateless broadcast signcryption avoids the key escrow problem of identity-based signcryption. At the same time, the method avoids the use of bilinear pairing and greatly improves data security. The efficiency of encryption and data authentication. In addition, the use of broadcast encryption to improve the efficiency of information transmission provides efficient and flexible data encryption and identity authentication for UAV self-organizing network data.

Description

technical field [0001] The present invention relates to the technical field of privacy protection and safety of unmanned aerial vehicles, more particularly, refers to a kind of broadcast signcryption based on lightweight non-certificate-free bilinear pairing in UAV ad hoc network (UAANET) protection method. Background technique [0002] UAV Ad-Hoc Network (UAANET), as a new type of multi-hop mobile ad-hoc network, has been favored due to its larger operating range, wider application scenarios and more flexible execution of air tasks. extensive attention. UAANET can assist other existing communication methods, greatly improving the working radius and work efficiency of the UAV application platform. Unmanned Aerial Vehicle (UAV) Internet will become an important development direction of communication in the future. UAV ad-hoc network came into being under this demand, which is developed on the basis of traditional mobile ad-hoc network (Mobile Ad-Hoc Network, MANET) and veh...

Problems solved by technology

Signcryption technology not only ensures the security of communication information transmitted in UAANET, but also realizes the non-repudiation of communication information, thereby enhancing the security and privacy of user (User) communication information. However, traditional signcryption technology can only realize the Signcryption for the transmission of communication information between individual users

[0006] At present, the existing certificateless signcryption schemes that support broadcast encryption often rely on a large number of bilinear pairs for encryption. The use of bilinear pairs will bring huge computing and communication overheads to UAANET

In UAANET, nodes (Node) have insufficient communication and computing capabilities due to size and power limitations. Therefore, these broadcast signcryption schemes that rely on a large number of bilinear pairs cannot meet the needs of UAANET in practical applications.

[0007] In summary, traditional encryption schemes cannot realize certificateless broadcast signcryption without bilinear pairing of communication information in UAANET, and some schemes rely on a large number of bilinear pairings to encrypt communication information, and the overall efficiency of the scheme is low
