Privacy-preserving access control for public wireless LAN utilizing the bitcoin blockchain
Published 2020-04-01“…In designing an access control scheme for public wireless LAN (WLAN),user privacy protection and user accountability are two conflict goals.A novel user management and access control scheme was proposed to solve this problem by utilizing the bitcoin blockchain and Intel SGX.It utilized unmodified bitcoin blockchain to manage the ownership of access credentials for users without relying on any trusted third party.It adopted Intel SGX-based mixing technology to enhance anonymity of users’ access credentials.It designed verification path rule to resolve the conflicts between the privacy-preserving and accountability objectives.The effectiveness and feasibility of the proposed scheme are also demonstrated by security analysis and performance evaluation.…”

High-precision indoor wireless positioning method based on generative adversarial network
Published 2021-06-01“…Because wireless signals are susceptible to interference during the propagation process, the application of traditional indoor positioning methods in real life is limited.Because location-based fingerprint positioning technology has the advantage of strong universality, it has become a current research hotspot.The number of fingerprint data is an important factor affecting the accuracy of fingerprint positioning, but the cost of collecting a large amount of fingerprint data is large.Therefore, how to use a small amount of fingerprint data to achieve higher positioning accuracy is a difficult point of fingerprint positioning technology.Aiming at this problem, a high-precision indoor wireless positioning method based on generative adversarial network was proposed.Firstly, fingerprint data was collected densely at equal intervals indoors, and the initial fingerprint data set was constructed, the part of the fingerprint data was selected in the initial fingerprint data set, and the generative adversarial network was used to obtain a large amount of fingerprint data from part of the fingerprint data.Then, based on these generated data, a KNN (k-nearest neighbor) model and a random forest model were used for location prediction.Experimental results show that this method can achieve high wireless positioning accuracy based on a small amount of fingerprint data, and the positioning accuracy can reach 15.4 cm.…”
