Input Space Coverage Matters

January 15, 2020
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei, Dimitris Simos
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

November 24, 2019
Author(s)
Peter M. Mell
In this work, we investigate how the governance features of a managed currency (e.g., a fiat currency) can be built into a cryptocurrency in order to leverage potential benefits found in the use of blockchain technology and smart contracts. The resulting

Implementing a Protocol Native Managed Cryptocurrency

November 24, 2019
Author(s)
Peter M. Mell, Aurelien M. Delaitre, Frederic J. de Vaulx, Philippe J. Dessauw
Previous work presented a theoretical model based on the implicit Bitcoin specification for how an entity might issue a cryptocurrency that mimics features of fiat currencies. Novel to this work were mechanisms by which the issuing entity could manage the
