Abstract :
We propose an efficient hardware architecture for the Blowfish algorithm. The speed is up to 4 bit/clock, which is 9 times faster than a Pentium. By applying operator-rescheduling method, the critical path delay is improved by 21.7%. We have successfully implemented it using Compass cell library targeted at a 0.6 /spl mu/m TSMC SPTM CMOS process. The die size is 5.7/spl times/6.1 mm/sup 2/ and the maximum frequency is 50 MHz.
