Serial:  EQ-010-93
 
DATE:  20 January 1993
REPLY TO ATTN OF:   XXXXXX NAME WITHHELD PER NSA XXXXXXXXX
 
SUBJECT:  Outside Crypto-mathematicians to Examine CLIPPER -
DECISION MEMORANDUM
 
TO:  Director
 
THRU:  D/DIR____,  ExDIR_____
 
1.  Assuming that there will be vocal public doubts expressed
about having a classified algorithm in the device we propose for
the U.S. law enforcement problem, the CLIPPER chip, we recommend
the following to address this:
 
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX  PARAGRAPH 2 BLACKED OUT  XXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXX  AS STILL SECRET PER NSA  XXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
 
3.  If such people agree to this clearance and non-disclosure
process, we could go over the algorithm with them to let them
develop confidence in its security, and we could also let them
examine the detail design of the CLIPPER chip made for the U.S.
law enforcement problem to assure themselves that there were no
trapdoors or other techniques built in.  This would likely
require crypto-mathematicians for the algorithm examination and
microelectronics chip design engineers for the chip examination.
