SSARES: Secure Searchable Automated Remote Email
Storage - A usable, secure email system on a remote
untrusted server
The increasing centralization of networked services
places user data at considerable risk. For example,
many users store email on remote servers rather
than on their local disk. Doing so allows users to
gain the benefit of regular backups and remote
access, but it also places a great deal of unwarranted
trust in the server. Since most email is stored in
plaintext, a compromise of the server implies the
loss of confidentiality and integrity of the email
stored therein. Although users could employ an
end-to-end encryption scheme (e.g., PGP), such
measures are not widely adopted, require action on
the sender side, only provide partial protection
(the email headers remain in the clear), and prevent
the users from performing some common operations,
such as server-side search.
To address this problem, we present Secure Searchable
Automated Remote Email Storage (SSARES), a novel
system that offers a practical approach to both
securing remotely stored email and allowing
privacy-preserving search of that email collection.
Our solution encrypts email (the headers, body, and
attachments) as it arrives on the server using
public-key encryption. SSARES uses a combination
of Identity Based Encryption and Bloom Filters to
create a searchable index. This index reveals little
information about search keywords and queries, even
against adversaries that compromise the server.
SSARES remains largely transparent to both the
sender and recipient. However, the system also
incurs significant costs, primarily in terms of
expanded storage requirements. We view our work as
a starting point toward creating privacy-friendly
hosted services.

MP3 version (14Mb, 60 minutes)
This talk will be on some of the basics of IPv6
including addressing, subnetting, and tools to test
connectivity. There will be a lab (network permitting),
and setups for an as of yet undisclosed flavor of
BSD as well as some of the well known daemons (Apache
2, SSHD) will be demonstrated. Setting up a BSD OS
as an IPv6 router and tunneling system will also
be covered.
Bio
Gene Cronk, CISSP-ISSAP, NSA-IAM is a freelance
network security consultant, specializing in *NIX
solutions. He has been working with computers for
well over 20 years, electronics for over 15, and
IPv6 specifically for 4 years. He has given talks
on IPv6 and a multitude of other topics at DefCon,
ShmooCon and other "underground" venues.
Gene is from Jacksonville, FL. When not involved
in matters concerning IPv6, he can be found gaming
(Anarchy Online), helping out with the Jacksonville Linux
User`s Group, being one of the benevolent
dictators of the Hacker Pimps
Security Think Tank, or fixing up his house.
