Tor网络作为第二代匿名互联网通信系统,常被网络罪犯用于进行网络攻击和欺诈等恶意活动,给网络安全带来了严重的威胁和挑战。为解决该问题,文章提出一种基于联邦学习的Tor流量检测方法。目前Tor流量检测以单主机检测为主,存在效率低和无法实现数据共享的问题,文章采用联邦学习技术和DP-SGD算法确保各参与方在保护用户隐私的前提下构建全局模型,解决数据孤岛问题。实验证明,该模型在保障用户数据隐私的同时,具有92%的整体准确率、90%的准确率和92%的召回率。文章通过对比实验进一步验证了模型在隐私保护和分类效果上的优越性。

Comprehensive SummaryThe detection of critical endogenous species, such as bacteria in microenvironments in the body, requires better imaging tools for visualization and monitoring of biological events. Bioluminescence imaging is the most popular strategy for obtaining real-time in living cells and organisms. Herein, we introduced a nitroaryl group on the C-3 position and a hydroxy group at the C-6 phenyl ring on furimazine to report the first bioluminescent probe (7) based on NanoLuc-furimazine bioluminescent pair for the detection of nitroreductase in bacteria. The probe, which possessed up to 560-fold intensity increase with a low detection limit of 16 ng/mL of nitroreductase, has the most efficient uncage efficiency in comparison with other bioluminescent congeners, thus enabling highly selective and sensitive visualization of NTR activity in a panel of clinical priority pathogens. Additionally, imaging of the recombinant strain as well as the NTR from mouse feces indicated the potential of this probe in the application of different mouse disease models.
