Subject: [tahoe-dev] press release: LeastAuthority.com announces Spy-Proof Backup
We're really happy to be offering our LAFS-based ciphertext storage
service to the public! Please spread the word. Thank you very much to
everyone in our little community for making things like this possible.

LeastAuthority.com Announces A Spy-Proof Storage Service
Wednesday, July 31, 2013
LeastAuthority.com today announced “Simple Secure Storage Service
(S4)”, a backup service that encrypts your files to protect them from the
prying eyes of spies and criminals.
“People deserve privacy and security in the digital data that make up our
daily lives.” said the company's founder and CEO, Zooko Wilcox-O'Hearn.
“As an individual or a business, you shouldn't have to give up control
over your data in order to get the benefits of cloud storage.”
verifiable end-to-end security
The Simple Secure Storage Service offers verifiable end-to-end security.
It offers “end-to-end security” because all of the customer's data is
encrypted locally — on the customer's own personal computer — before it is
uploaded to the cloud. During its stay in the cloud, it cannot be
decrypted by LeastAuthority.com, nor by anyone else, without the
decryption key which is held only by the customer.
S4 offers “verifiable end-to-end security” because all of the source code
that makes up the Simple Secure Storage Service is published for everyone
to see. Not only is the source code publicly visible, but it also comes
with Free (Libre) and Open Source rights granted to the public allowing
anyone to inspect the source code, experiment on it, alter it, and even to
distribute their own version of it and to sell commercial services.
Wilcox-O'Hearn says “If you rely on closed-source, proprietary software,
then you're just taking the vendor's word for it that it actually provides
the end-to-end security that they claim. As the PRISM scandal shows, that
claim is sometimes a lie.”
The web site of LeastAuthority.com proudly states “We can never see your
data, and you can always see our code.”.
trusted by experts
The Simple Secure Storage Service is built on a technology named
“Least-Authority File System (LAFS)”. LAFS has been studied and used by
computer scientists, hackers, Free and Open Source software developers,
activists, the U.S. Defense Advanced Research Projects Agency, and the
U.S. National Security Agency.
The design has been published in a peer-reviewed scientific workshop:
Wilcox-O'Hearn, Zooko, and Brian Warner. “Tahoe: the least-authority
filesystem.” Proceedings of the 4th ACM international workshop on Storage
security and survivability. ACM, 2008.
It has been cited in more than 50 scientific research papers, and has
received plaudits from the U.S. Comprehensive National Cybersecurity
Initiative, which stated: “Systems like Least-Authority File System are
making these methods immediately usable for securely and availably storing
files at rest; we propose that the methods be further reviewed, written
up, and strongly evangelized as best practices in both government and
Dr. Richard Stallman, President of the Free Software Foundation
(https://fsf.org/) said “Free/Libre software is software that the users
control. If you use only free/libre software, you control your local
computing — but using the Internet raises other issues of freedom and
privacy, which many network services don't respect. The Simple Secure
Storage Service (S4) is an example of a network service that does respect
your freedom and privacy.”
Jacob Appelbaum, Tor project developer (https://www.torproject.org/)
and WikiLeaks volunteer (http://wikileaks.org/), said “LAFS's design
acknowledges the importance of verifiable end-to-end security through
cryptography, Free/Libre release of software and transparent peer-reviewed
The LAFS software is already packaged in several widely-used operating
systems such as Debian GNU/Linux and Ubuntu.
