Abstract: In a wireless sensor network, authentication of multiple nodes can effectively reduce the overhead of node communication and improve the security of wireless sensor network operation. However, when the node was authenticated by existing methods, the positional information of the node was easily exposed, resulting in a high calculation repetition rate and increased consumption of node communication. A random unite authentication method based on RSA and trusted nodes was proposed. The multi-node authentication model of the RSA method was used to effectively authenticate other nodes in the wireless sensor network. The node trust degree was introduced, and the node authentication key was updated by the identity-based and bilinear theory. After the trust reputation management based on the Beta distribution node was used to calculate the trust degree of the node, it was verified whether the trust degree of the communication node was trustworthy to the node; the verification result was identified. Finally, the method of combining symmetric cryptography with node information authentication code was used to implement trusted node authentication in wireless sensor networks. Experiments showed that the authentication node results of this mechanism were stable, which overcame the shortcomings of low stability of multi-node authentication results in the current method.
