As once-proprietary mission-specific information systems migrate onto
the Web, traditional security analysis cannot sufficiently protect eac
h subsystem atomically. The Web encourages open, decentralized systems
that span multiple administrative domains. Trust Management is an eme
rging framework for decentralizing security decisions that helps devel
opers and others in asking ''why'' trust is granted rather than immedi
ately focusing on ''how'' cryptography can enforce it. In this poster,
we summarize the implications of Trust Management to future Web appli
cations. (C) 1998 Published by Elsevier Science B.V. All rights reserv
