Testing is the most commonly used approach for software assurance, yet it remains as much judgement and art as science. Structural coverage adds some rigor to the process by establishing formally defined criteria for some notion of test completeness, but

Resilient Interdomain Traffic Exchange: BGP Security and DDos Mitigation

December 17, 2019
Author(s)
Kotikalapudi Sriram, Douglas C. Montgomery
In recent years, numerous routing control plane anomalies, such as Border Gateway Protocol (BGP) prefix hijacking and route leaks, have resulted in denial-of-service (DoS), unwanted data traffic detours, and performance degradation. Large-scale distributed

Augmenting Fiat Currency with an Integrated Managed Cryptocurrency
