Secure ad-hoc network single-path routing data transmission method

Abstract

The invention discloses a secure ad-hoc network single-path routing data transmission method for the problem that ad-hoc network data security is not sufficiently ensured. A stable network is established; under the condition that a new node joins the network and certain node in an original network is broken down, malicious node detection is carried out on the network; and a reputation evaluation formula parameter is updated in real time, thereby achieving a purpose of accurately detecting a malicious parameter. If a malicious node is detected, the node is processed as a breakdown node, and the security of the network is ensured. Data is encrypted through adoption of a key table, and the encrypted data is sent. In the original network, optimum path selection is carried out through a routing path hop count minimization rule and a link busy and idle rule between a sending node and a destination node. After a path is selected, the encrypted data is decrypted according to a corresponding key in the key table, and the original data information is restored.

Description

technical field [0001] The invention relates to the field of network data security, in particular to a safe ad-hoc network single-path routing data transmission method. Background technique [0002] The ad-hoc network is an ad hoc network, and each access point AP can connect to other nodes wirelessly. Nodes may not pass through the infrastructure network. A stochastic topology is formed when nodes act as routers and are free to move arbitrarily. Ad-hoc networks can prove their efficiency in different fields, but they are very vulnerable to security attacks, and this problem is also one of the main challenges of today's networks. [0003] In node mobility, security depends on several parameters, including authentication, confidentiality, integrity, non-repudiation, and availability. Any parameter has an important impact on the security guarantee. Without authentication, an attacker can masquerade as a node, enabling unauthorized access to resources and sensitive informat...
