Research on secure communication of industrial wireless WIA-PA networks

Abstract

While industrial wireless technology optimizes the communication performance of the industrial network, security has also become a key problem restricting the popularization of an industrial wireless network communication application. As an industrial wireless network protocol independently developed in China, the WIA-PA standard urgently needs to establish a set of independent and controllable security mechanisms. Aiming at the security problems faced by industrial wireless WIA-PA networks, this paper proposes a secure communication scheme based on National secret algorithm, designs node identity authentication, key agreement, and end-to-end secure transmission suitable for WIA-PA networks, and develops a secure communication system based on National secret algorithm based on self-developed chip TF2400 and WIA-PA protocol stacks, the feasibility of the proposed communication scheme and the test results of the confidentiality of the network show the effectiveness of the proposed secure communication scheme.
