Research on Digital Integrity Authentication in Encrypted Domain Based on Wireless LAN Big Data

Abstract

In order to improve the security of digital integrity authentication in encrypted domain, it is necessary to design the big data encryption of wireless LAN, propose the encryption domain digital integrity authentication algorithm based on the big data of wireless LAN, construct the data distributed structure model of the big data encryption domain digital integrity authentication of wireless LAN under the same state public key encryption system, extract the encrypted statistical feature of cloud storage information, use the method of homomorphic data fusion to carry on the fuzzy clustering of the big data of wireless LAN, combine the method of vector quantization to carry on the scheduling of big data segmentation fusion of wireless LAN, adopt the random coding control scheme to design the digital integrity authentication of the big data encryption domain of wireless LAN in the segment interval, construct the fuzzy clustering algorithm to construct the key encryption and key decryption, and optimize the design of the digital integrity of the big data encryption domain of wireless LAN. The simulation results show that the method has good information fusion and strong anti-decipherment ability, and improves the security of big data.
