AN EFFICIENT AND LIGHTWEIGHT SOURCE PRIVACY PROTECTING SCHEME FOR SENSOR NETWORKS USING GROUP KNOWLEDGE

Providing source privacy is a critical security service for sensor networks.However, privacy preserving in sensor networks is a challenging task, particularly due to the limited resources of sensor nodes and the threat of node capture attack.On the other hand, existing works roneverhart.com use either random walk path or fake packets injection, bot

This paper evaluates the possibility of analyzing the composition of high-quality copper scrap with X-ray fluorescence spectrometry (XRF) turbo air m3f72-3-n instead of electrogravimetry combined with flame atomic absorption spectroscopy (EG+FAAS) method.The evaluation of the methods was performed on three real copper scraps, the composition of whi
