  abstract = {Wireless Sensor Networks (WSN) are becoming a key tech-
nology in the support of pervasive and ubiquitous services. The previous
notion of \PKC is too expensive for WSN" has changed partially due to
the existence of new hardware and software prototypes based on Elliptic
Curve Cryptography and other PKC primitives. Then, it is necessary
to analyze whether it is both feasible and convenient to have a Public
Key Infrastructure for sensor networks that would allow the creation of
PKC-based services like Digital Signatures.},
