Abstract
Rivest and Lampson have recently introduced SDSI, a Simple Distributed
Security Infrastructure. One of the important innovations of SDSI is the use
of linked local name spaces. This paper suggests a logical explanation of
SDSI's local name spaces, as a complement to the operational explanation
given in the SDSI definition.
