Problems solved by technology

[0004] However, the terminal self-organizing network composed of intelligent mobile terminals cannot rely on the infrastructure. In this case, the traditional method of key negotiation based on the certificate provided by the trusted third party and the technology combined with the public key theory will no longer be feasible.

Abstract

The invention discloses a mobile terminal network key negotiation method based on a bock chain. The mobile terminal network comprises a plurality of nodes, the node information of the nodes is stored in the form of blocks, a plurality of blocks form a bock chain, the block data in the bock chain are the node information of the nodes, and the node information at least comprises a public session key. The method comprises the following steps: searching the public session keys of the nodes in the bock chain; and obtaining session keys among the nodes according to the public session keys to perform communication. According to the mobile terminal network key negotiation method disclosed by the invention, the bock chain can be regarded as a credible node of a consensus mechanism, and the user in the mobile terminal network participates in the key negotiation according to the features of the bock chain without depending on a credible third party.

Description

technical field [0001] The invention relates to the technical field of cryptography in information security, in particular to a blockchain-based mobile terminal network key agreement method. Background technique [0002] With the continuous development of wireless communication technology in the information age, smart mobile terminals have become an irreplaceable part of people's lives. The communication network composed of intelligent mobile terminals can be divided into a network with infrastructure (such as a base station) and an ad hoc network according to whether it has infrastructure. Self-organizing networks have the characteristics of topological dynamics, multi-hop nodes, decentralized distribution, and no fixed infrastructure, which lead to new challenges in many traditional communication network technologies. However, due to the good flexibility and scalability of this kind of intelligent mobile terminal self-organizing network, it is widely used in many fields, ...
