Cryptography Reference
In-Depth Information
Simply thinking of these algorithms as tools for disguising informa-
tion is a mistake. Some offer cryptographic security at the same time
as an effective disguise. Some are deeply intertwined with crypto-
graphic algorithms, while others act independently. Some are diffi-
cult to break without the key while others offer only basic protection.
Trying to classify the algorithms purely as steganography or cryptog-
raphy imposes only limitations. It may be digital information, but
that doesn't mean there aren't an infinite number forms, shapes, and
appearances the information may assume.
1.0.1 Reasons for Secrecy
There are many different reasons for using the techniques in this
topic and some are scurrilous. There is little doubt that the Four
Horsemen of the Infocalypse- the drug dealers, the terrorists, the
child pornographers, and the money launderers- will find a way to
use the tools to their benefit in the same way that they've employed
telephones, cars, airplanes, prescription drugs, box cutters, knives,
libraries, video cameras and many other common, everyday items.
There's no need to explain how people can hide behind the veils of
anonymity and secrecy to commit heinous crimes.
But these tools and technologies can also protect the weak. In
topic's defense, here's a list of some possible good uses:
1. So you can seek counseling about deeply personal problems
like suicide.
2. So you can inform colleagues and friends about a problemwith
odor or personal hygiene.
3. So you can meet potential romantic partners without danger.
4. So you can play roles and act out different identities for fun.
5. So you can explore job possibilities without revealing where
you currently work and potentially losing your job.

without fear of recrimination.
7. So you can leak information to the press about gross injustice
or unlawful behavior.
8. So you can take part in a contentious political debate about,
say, abortion, without losing the friendship of those who hap-
pen to be on the other side of the debate.
