A secure underwater transmission method supporting obfuscation and zero-knowledge

Abstract

The invention discloses a security underwater transmission method capable of supporting confusion and zero knowledge. The method includes following steps: (1) an initialization stage: a gateway GW generates key materials and distributes the key materials to an underwater vehicle A and an underwater vehicle B; (2) a neighbor discovery stage: the underwater vehicle A and the underwater vehicle B generate and broadcast temporary identities when the two underwater vehicles meet underwater; and (3) a data transmission stage: a sending party firstly generates primary identity information of both parties, performs data encryption and signature, and sending related information to a receiving party; and the receiving party receives the information, verifies whether the receiving party is a correct receiving party, then calculates the temporary identity of the sending party, and decrypts and verifies the received data. According to the method, opponents can be prevented from detecting the related information of the underwater vehicle or counting, and the problem of the conventional underwater wireless communication is solved.

Description

technical field [0001] The invention relates to a safe underwater transmission method supporting confusion and zero knowledge, which belongs to the underwater wireless communication safety technology. Background technique [0002] In the past few years, underwater wireless communication (UWC for short) technology has been widely used in various fields, such as national security and defense, collection of scientific data at seabed stations, environmental pollution monitoring systems, remote control of the offshore oil industry, and disaster detection and monitoring. early warning. In order to ensure the security of communication between underwater vehicles, it is necessary to design corresponding data transmission protocols to provide integrity and confidentiality protection for the transmitted information. [0003] No matter how the technology is implemented, a typical data transmission protocol for a UWC system includes three entities: the gateway GW, the underwater vehicl...

AI Technical Summary

Problems solved by technology

Unfortunately, current underwater protocols are still based on legacy security infrastructure

[0006] (2) Confusability is another serious problem of underwater data transmission protocols

By doing this, the attacker will not be able to determine the specific vehicle information and number, yet obfuscation features are largely ignored in current underwater security protocols

[0007] (3) Zero knowledge is the third serious problem of underwater data transmission protocols

More importantly, in focusing on this research topic, we found no cryptographic primitives that can be directly applied to solve all the above problems
