摘要
随着现场可编程门阵列(FPGA)芯片在安全领域上的广泛应用,有关FPGA密码芯片的抗(DPA)研究也越来越受关注,但目前的研究成果大多针对智能卡的安全防护。在研究各种电路级安全防护技术的基础上,采用硬件宏的方法将双轨和预充电技术应用于FPGA芯片的数据加密标准算法(DES)硬件结构,通过DPA攻击实验后发现,未加防护措施的DES加密系统难以抵御DPA攻击,而加防护措施的加密系统具有抗DPA攻击的能力。
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.
