With the widespeard application of field programmable gate array(FPGA) chip in the securtity field,the anti DPA-attack research of FPGA ciphering chip are getting much more attention,but most of the present research achievements focus on the security of smart cards.Based on the protection technique research of circuit,the dual-rail and pre-charge technique is applied in the data encryption standard(DES) hardware structure of the FPGA chip with the hard macros method.The attacking experiment of DPA demonstrates that without pretecting measure DES enciphering system can′t defend DPA,but enciphering system using pretecting measure has the ability to resist DPA-attack.
