Good survey article on crypto hardware

There's a good article on software and hardware for reconfigurable computer systems (e.g. FPGA's) in the June 2002 ACM Computing Surveys for people who are interested in that sort of thing. This is the sort of hardware which is often used for crypto when a full ASIC isn't economically viable (one of those combined PPC+FPGA cores would be quite interesting for crypto use). Peter.
