%X The paper focuses on the synthesis of a highly parallel
   reconfigurable hardware implementation for the International
   Data Encryption Algorithm (IDEA). Currently, IDEA is well
   known to be a strong encryption algorithm. The use of such
   an algorithm within critical applications, such as military,
   requires efficient, highly reliable and correct hardware
   implementation. We will stress the affordability of such
   requirements by adopting a methodology that develops
   reconfigurable hardware circuits by following a
   transformational programming paradigm. The development
   starts from a formal functional specification stage. Then,
   by using function decomposition and provably correct data
   refinement techniques, powerful high\-order functions are
   refined into parallel implementations described in
   Hoare\[rs]s communicating sequential processes
   notation(CSP). The CSP descriptions are very closely
   associated with Handle\-C hardware description language
   (HDL) program fragments. This description language is
   employed to target reconfigurable hardware as the final
   stage in the development. The targeted system in this case
   is the RC\-1000 reconfigurable computer. In this paper
   different designs for the IDEA corresponding to different
   levels of parallelism are presented. Moreover,
   implementation, realization, and performance analysis and
   evaluation are included.
