HC-BGP: A light-weight and flexible scheme for securing prefix ownership

Ying Zhang, Zheng Zhang, Z. Morley Mao, Y. Charlie Hu
2009 2009 IEEE/IFIP International Conference on Dependable Systems & Networks  
The Border Gateway Protocol (BGP) is a fundamental building block of the Internet infrastructure.  ...  Prefix hijacking is one such misbehavior where an attacker AS injects false routes to the Internet routing system that misleads victim's traffic to the attacker AS.  ...  The key idea of HC-BGP is inspired by an empirical study we conducted to understand the most common routing dynamics.  ...

Mining Crosscutting Concerns through Random Walks

Charles Zhang, Hans-Arno Jacobsen
2012 IEEE Transactions on Software Engineering  
The random walks are performed on the concept graphs extracted from the program sources to calculate metrics of "utilization" and "aggregation" for each of the program elements.  ...  We rank all the program elements based on these metrics and use a threshold to produce a set of candidates that represent crosscutting concerns(CCs).  ...  Special thanks to Andrew Clement for the technical help and insights and to Julie Waterhouse of IBM Canada for provisioning the project and reviewing an early draft of this paper.  ...
