Abstract
The rapid expansion of the Internet means that users increasingly want
to interact with each other. Due to the openness and unsecure nature
of the net, users often have to rely on firewalls to protect their
connections. Firewalls, however, make real-time interaction and
collaboration more difficult. Firewalls are also complicated to
configure and expensive to install and maintain, and are inaccessible
to small home offices and mobile users.
The Enclaves approach is to transform user machines into ``enclaves,''
which are protected from outside interference and attacks. Using
Enclaves, a group of collaborators can dynamically form a secure
virtual subnet within which to conduct their joint business.
This paper describes the design and implementation of the Enclaves
toolkit, and some applications we have built using the toolkit.
