Title: SKIPJACK Review - Interim Report - The SKIPJACK Algorithm Authors: Ernest F. Brickell Dorothy E. Denning Stephen T. Kent David P.

Because SKIPJACK is but one component of a large, complex system, and because the security of communications encrypted with SKIPJACK depends on the security of the system as a whole, the review was extended to encompass other components of the system. The purpose of this Interim Report is to report on our evaluation of the SKIPJACK algorithm. A later Final Report will address the broader system issues.
