Distributed UAV key agreement method based on trusted platform

Abstract

The invention discloses an authentication and key agreement method based on a trusted platform in a distributed unmanned aerial vehicle environment, which mainly solves the problem that the prior art cannot guarantee the safe calling of trusted computing services. It includes: remote authentication between early warning aircraft nodes, key negotiation between UAV request node and early warning aircraft service node. Remote authentication includes two stages: obtaining platform measurement information and platform verification; key negotiation is a set of communication procedures for key exchange and message verification between UAVs and early warning aircraft, to obtain shared keys, and use data volume The shared key is updated in a combination of management and request times management. In the present invention, the remote authentication between the early warning aircraft ensures the credibility and authenticity of both communication parties; the shared key is used between the UAV and the early warning aircraft to encrypt the trusted service data, which ensures the safe transmission of data; the early warning aircraft service node provides The key management mechanism ensures the validity and confidentiality of the shared key.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a distributed trusted service scheme, which can be used for remote identity authentication between early warning aircraft and trusted service function calls of drones to early warning aircraft. Background technique [0002] The fleet composed of unmanned aerial vehicles and early warning aircraft can be used to perform tasks such as aerial photography, survey, autonomous reconnaissance and automatic attack, and has a wide range of applications and scientific research value. With the continuous development of technology, the application of drones is becoming more and more extensive, and the proportion of software in the airborne system is gradually increasing. The related security issues are becoming more and more serious, which has attracted widespread attention. [0003] With the rapid development of networking and integration of airborne systems, airbor...
