Two-factor authentication method and two-factor authentication device for wireless sensor network and network comprising two-factor authentication device

Abstract

The invention discloses a two-factor authentication method and a two-factor authentication device for a wireless sensor network and a network comprising the two-factor authentication device. The two-factor authentication device comprises a gateway node, an intelligent terminal, a sensor node and a two-factor authentication module, and the gateway node, the intelligent terminal and the sensor node are communicated with each other. The Merkle hash tree based two-factor authentication method for the wireless sensor network is applied to the two-factor authentication module. The two-factor authentication method includes the steps of gateway pre-authentication: performing DoS (disk operating system)-attack resisting gateway pre-authentication on the basis of the Merkle hashtree; bidirectional authentication among gateway and sensor nodes: authenticating the sensor node by the gateway node after the sensor node finishes in authenticating an access request from the gateway node, wherein during bidirectional authentication, one-way hash is performed after connection with sensor node ID (identification) is established, so that personalized safety parameters for the sensor node are formed to resist attacks from gateway counterfeit and data counterfeit caused by leakage of the safety parameters. The invention further provides an interconnection computer network comprising the two-factor authentication device for the wireless sensor network.

AI Technical Summary

Problems solved by technology

Neither of these two methods can resist denial-of-service attacks initiated by attackers and malicious legitimate users, and there are deficiencies in robustness

In addition, considering the security parameters distributed by gateway nodes to sensing nodes, some are directly stored, and some are stored after simple processing. After the sensing nodes are captured and the security parameters are leaked, gateway impersonation attacks and data forgery attacks will be triggered

Cannot guarantee many forms of security

[0007] In addition, in the existing two-factor authentication protocol, most of the secret parameters shared by the gateway node and the sensing node are stored in the sensing node through plain text storage, and some are distributed to the sensing node after simple processing. These two methods The common disadvantage is that once the sensing node is captured and the secret parameters are released through side channel attacks, it is very easy to launch gateway impersonation attacks and data forgery attacks combined with eavesdropping
