【摘要】 文中提出了一种抗旁路功耗攻击的分组密码电路的自动防护方法,重点介绍了密码电路防护和自动防护方法,如隐藏技术、掩码技术、追踪算法等。通过修改高级程序语言代码实现自动防护,给出了应用于DES密码算法的两种防护方案且具有较好的防护效果。更多还原

【Abstract】 This paper presents an antomatic protection of block cipher circuit against power analysis,and focuses on introdution to the cipher circuit protection and automatic protection method,including hiding technology,mask technology and tracking algorith. By modifying the programming language code to achieve the antomatic protection,if shows two protection schemes,which are applied to DES cipher algorithm,and has a good protection effect.更多还原
