Random key graphs, also
known as uniform random intersection graphs, appear in application areas as
diverse as clustering analysis, collaborative filtering in recommender systems
and key distribution in wireless sensor networks (WSNs). In this last context
they are naturally associated with a random key predistribution scheme recently
proposed by Eschenauer and Gligor.
In this talk we present some recent results concerning the structure of random
key graphs. Similarities and differences with Erdos-Renyi graphs are presented.
Highlights include: (i) A zero-one law for graph connectivity (and its critical
scaling) as the number of nodes becomes unboundedly large; (ii) A zero-one law
(and its critical scaling) for the appearance of triangles; and (iii) Clustering
coefficients and the "small world" property of random key graphs.

M. Makowski received the Licence en Sciences Mathematiques from the Universite
Libre de Bruxelles in 1975, the M.S. degree in Engineering-Systems Science from
U.C.L.A. in 1976 and the Ph.D. degree in Applied Mathematics from the University
of Kentucky in 1981. In August 1981, he joined the faculty of the Electrical
Engineering Department at the University of Maryland College Park, where he is
Professor of Electrical and Computer Engineering. He has held a joint
appointment with the Institute for Systems Research since its establishment in
1985. Armand Makowski was a C.R.B. Fellow of the Belgian-American Educational
Foundation (BAEF) for the academic year 1975-76; he is also a 1984 recipient of
the NSF Presidential Young Investigator Award and became an IEEE Fellow in 2006.
His research interests lie in applying advanced methods from the theory of
stochastic processes to the modeling, design and performance evaluation of
engineering systems, with particular emphasis on communication systems and
