Does Real Exchange Rate Volatility Affect Sectoral Trade Flows?

This paper investigates empirically the effect of real exchange rate volatility on sectoral bilateral trade flows between the US and her top thirteen trading countries. Our investigation also considers those effects on trade flows which may arise through changes in income volatility and the interaction between income and exchange rate volatilities. We provide evidence that exchange rate volatility mainly affects sectoral trade flows of developing but not that of developed countries. We also find that the effect of the interaction term on trade flows is opposite that of exchange rate volatility yet there is little impact arising from income volatility

PeerHunter: Detecting Peer-to-Peer Botnets through Community Behavior Analysis

Peer-to-peer (P2P) botnets have become one of the major threats in network security for serving as the infrastructure that responsible for various of cyber-crimes. Though a few existing work claimed to detect traditional botnets effectively, the problem of detecting P2P botnets involves more challenges. In this paper, we present PeerHunter, a community behavior analysis based method, which is capable of detecting botnets that communicate via a P2P structure. PeerHunter starts from a P2P hosts detection component. Then, it uses mutual contacts as the main feature to cluster bots into communities. Finally, it uses community behavior analysis to detect potential botnet communities and further identify bot candidates. Through extensive experiments with real and simulated network traces, PeerHunter can achieve very high detection rate and low false positives.Comment: 8 pages, 2 figures, 11 tables, 2017 IEEE Conference on Dependable and Secure Computin
