NASA/JPL: WEDDS: The WITS encrypted Data Delivery System (PDF)
Quote:
Abstract-WEDDS, the WITS Encrypted Data Delivery
System, is a framework for supporting distributed mission
operations by automatically transferring sensitive mission
data in a secure and efficient manner to and from remote
mission participants over the Internet. WEDDS was
originally developed as part of WITS, the Web Interface for
Telescience, and will be used in the 1998 Mars Polar Lander
Mission to support distributed mission operations over the
Internet for the first time in NASA history. WEDDS is
written in Java, and is designed to provide secure distributed
operations capabilities to any existing mission application
with little modification, and in a manner that is nearly
transparent to the existing application and its users.
WEDDS relies on the NASA Public Key Infrastructure
(PKI) to verify the identity of remote users. Remote users
must apply in person at a NASA security office or another
trusted security authority in order to receive a digital
certificate. All connections are made using the Secure
Sockets Layer (SSL) protocol in conjunction with the user’s
certificate, and all transmissions are protected against
eavesdropping through encryption with the Triple-DESEDE3
algorithm.
