	The availability of balletin-board software is your
key to rapid and secure communication. Bulletin-
board software allows your home computer to
function as a message center. Some communi-
cations packages, such as Shareware's"RBBS-PC,"
are excollent for in-bonnd messages; others, such as
Hayes "SmartCom II," are ideal for dialing out. It
matters little wh~ch software you choosc. The
important thing is to get it and use it. Would you
rather rely on the U.S. Postal Service to provide you
with rapid and secare communicat~on?

	In defense of your right to process data, you necd
to dc~clop the Icind of mentality that creates a login
routine which asks for the day of the weck. If you
answer with thc day of the week, the computer shnts
dewn; the proper response is your aunt's maiden
name. This is the modern way to fight unwarranted
search and seizure.

	You cen set up a secure bulletin board system and
annonnce it to those with whom you would sharc
data. Sun~val information, analysis of econom~c
and political news, ~nformation about life~xtension

and more can be available to you and a handfnl of
friends you may never meet face~to~face.

"Piracy in ihe ISOOs and 1600s
was caused by nationalist wars
and mereantilist tariffs. The
success of piraies on ihe high
scas Ied to the era of laissez
faire. So, too, has software
pirary led to admission by some
that foree of law is inferiar to
the realities of the market-
place. "

	Realize that given unlimited tsme and resources,
any code or cipher can be broken. However, welfarc
department case workers and alcoLol tax agents are
governmcnt employees; their abillty to follow o~
vious clues to a lo~pcal conclusion is limited. On thc
other hand, if the stakes are high enongh thc federal
goverament will devote incrediblc resources in a
brute forcc or~tempest'' attack.

	Thc public key crypto-system developed at
Stanford by Mcrkle, Hellman and Diffie was
broken by Adi Shamir. Working at the Weirmann
Institute in Israel, Shamir was cont~nning the
investigations begun with Rivest and Adlemann at
MIT on public key cryptosystems. At a cryp~o-
system conference held in Santa Barbara, Calif-
ornia, Adlemann demonstrated Shamir's work
using an Apple II computer.

	The Stanford public key system was broken by
the brilliant mathematical insights of ~ single
person. The Stanford people have in turn targetted
thc Data Encryption Algorithm devised for the
Department of Commerce's Bureau of Standards.
The algorithm is supposed to be used by all banks
and other federal ~nstitutions (for instance, it is used
to transfer Air Force paychecks). However, the U.S.
Goverament does not allow the DEA to be used for
even the lowest level of military secunty.

	The team at Stanford has set a pnce of S5 million
to bu~ld a machinc with enongh parallel processors
to take apart DEA transmissions in less than a day.

	Clearly, no cryptosystem is completely secure.
However, ~t is possible to devise secure means for

communicstion that are unambiguous, easy to use
and difficult to bre~.

"Yon con set ~p a serure balletin

ation, analysis of economic and

	The "dic~ionary code" meets these criteria. Those
who would communicate securely decide upon one
or more books which all own. The Christian Bible,
tbe Oxford English Dictionary, or an encyclopedia
are obvious choices. Obseure editions of fairy tales,
nursery rhymes or geology texts could also serve as
code dictionaries.
