Guaranteeing Anonymity in Attribute-Based Authorization
Erin Lanus, Charles J. Colbourn, Gail-Joon Ahn
Attribute-based methods, such as attribute-based access control and attribute-based encryption, make decisions based on attributes possessed by a subject rather than the subject's…
Sets of mutually orthogoval projective and affine planes
Charles J. Colbourn, Colin Ingalls, Jonathan Jedwab +3
A pair of planes, both projective or both affine, of the same order and on the same pointset are orthogoval if each line of one plane intersects each line of the other plane in at…
Balanced and Swap-Robust Trades for Dynamical Distributed Storage
Chao Pan, Ryan Gabrys, Xujun Liu +2
Trades, introduced by Hedayat, are two sets of blocks of elements which may be exchanged (traded) without altering the counts of certain subcollections of elements within their con…
Distributing hash families with few rows
Charles J. Colbourn, Ryan E. Dougherty, Daniel Horsley
Column replacement techniques for creating covering arrays rely on the construction of perfect and distributing hash families with few rows, having as many columns as possible for…
Disjoint spread systems and fault location
Charles J. Colbourn, Bingli Fan, Daniel Horsley
When factors each taking one of levels may affect the correctness or performance of a complex system, a test is selected by setting each factor to one of its levels and det…
Access Balancing in Storage Systems by Labeling Partial Steiner Systems
Yeow Meng Chee, Charles J. Colbourn, Hoang Dau +4
Storage architectures ranging from minimum bandwidth regenerating encoded distributed storage systems to declustered-parity RAIDs can be designed using dense partial Steiner system…
