FREQUENTLY ASKED QUESTIONS
About Today's Cryptography
by Paul Fahn
RSA Laboratories
This new document discusses in detail many aspects of current cryptography,
whether theoretical, practical, legal or commercial. It is a broad guide to
the state of cryptography today, and includes both introductory and advanced
topics. Although not a technical document, this FAQ gives extensive
bibliographic references to the technical literature for all major areas
of cryptography. The FAQ will be continually edited to reflect new
developments; it is thus an important guide for those who wish to be kept
up to date on the latest legal and political controversies as well as the
latest achievements in factoring.
`Frequently Asked Questions' is available via anonymous ftp from rsa.com,
in the pub/faq directory. It is available in both postscript and LaTeX
formats. Those without ftp capability can obtain a hard copy by sending
$20 (to cover expenses) to RSA Laboratories, 10 Twin Dolphin Drive,
Redwood City, CA 94065.
Any questions or comments may be sent to faq-editor(_at_)rsa(_dot_)com(_dot_)
