The President
The White House
Washington, DC 20500
Dear Mr. President,
We are writing to you regarding the "Clipper" escrowed
encryption proposal now under consideration by the White House.
We wish to express our concern about this plan and similar
technical standards that may be proposed for the nation's
communications infrastructure.
The current proposal was developed in secret by federal
agencies primarily concerned about electronic surveillance, not
privacy protection. Critical aspects of the plan remain
classified and thus beyond public review.
The private sector and the public have expressed nearly
unanimous opposition to Clipper. In the formal request for
comments conducted by the Department of Commerce last year, less
than a handful of respondents supported the plan. Several hundred
opposed it.
If the plan goes forward, commercial firms that hope to
develop new products will face extensive government obstacles.
Cryptographers who wish to develop new privacy enhancing
technologies will be discouraged. Citizens who anticipate that
the progress of technology will enhance personal privacy will
find their expectations unfulfilled.
Some have proposed that Clipper be adopted on a voluntary
basis and suggest that other technical approaches will remain
viable. The government, however, exerts enormous influence in the
marketplace, and the likelihood that competing standards would
survive is small. Few in the user community believe that the
proposal would be truly voluntary.
The Clipper proposal should not be adopted. We believe that
if this proposal and the associated standards go forward, even on
a voluntary basis, privacy protection will be diminished,
innovation will be slowed, government accountability will be
lessened, and the openness necessary to ensure the successful
development of the nation's communications infrastructure will be
threatened.
We respectfully ask the White House to withdraw the Clipper
proposal.
Sincerely,
Public Interest and Civil Liberties Organizations
