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

Blockchain Technology Overview

October 3, 2018
Author(s)
Dylan J. Yaga, Peter M. Mell, Nik Roby, Karen Scarfone
Blockchains are tamper evident and tamper resistant digital ledgers implemented in a distributed fashion (i.e., without a central repository) and usually without a central authority (i.e., a bank, company, or government). At their basic level, they enable

Quantifying Information Exposure in Internet Routing

September 6, 2018
Author(s)
Peter M. Mell, Assane Gueye, Christopher A. Schanzle
Data sent over the Internet can be monitored and manipulated by intermediate entities in the data path from the source to the destination. For unencrypted communications (and some encrypted communications with known weaknesses), eavesdropping and man-in

Cryptocurrency Smart Contracts for Distributed Consensus of Public Randomness

October 7, 2017
Author(s)
Peter M. Mell, John M. Kelsey, James Shook
Most modern electronic devices can produce a random number. However, it is dicult to see how a group of mutually distrusting entities can have con dence in any such hardware-produced stream of random numbers, since the producer could control the output to

Measuring and Improving the Effectiveness of Defense-in-Depth Postures

January 26, 2017
Author(s)
Peter M. Mell, James Shook, Richard Harang
Defense-in-depth is an important security architecture principle that has significant application to industrial control systems (ICS), cloud services, storehouses of sensitive data, and many other areas. We claim that an ideal defense-in-depth posture is

Linear Time Vertex Partitioning on Massive Graphs

March 7, 2016
Author(s)
Peter M. Mell, Richard Harang, Assane Gueye
The problem of optimally removing a set of vertices from a graph to minimize the size of the largest resultant component is known to be NP-complete. Prior work has provided near optimal heuristics with a high time complexity that function on up to hundreds

On the Internet Connectivity in Africa

November 18, 2015
Author(s)
Assane Gueye, Peter Mell, Desire Banse, Faical Y. Congo
This study measures and documents growth of Internet connectivity in Africa from 2010 to 2014 with a focus on inter-country relationships. We evaluate both intra-continent connectivity as well as connectivity to other continents. An initial analysis
