【摘要】 提出了可重构密码协处理器的概念并论述了其设计原理。所谓可重构密码协处理器实际上是一个其内部逻辑电路结构和功能可被灵活改变的密码处理单元,它能够在主处理器的控制和驱动下灵活、快速地实现多种不同的密码操作,以便适应不同密码算法的需求。基于可重构密码协处理器的可重构密码系统具有灵活、快速、安全的特点,在保密通讯和网络安全等领域中具有良好的应用前景。更多还原

【Abstract】 The concept and design principle of reconfigurable cipher coprocessor are proposed in this paper.The cipher coprocessor is a cipher processing unit which functions and architecture can be changed neatly.Under the control and drive of the main processor,it can implement many different cipher operations conveniently and quickly so as to match different demands of different cipher algorithms.The cipher system based on reconfigurable cipher coprocessor is flexi-ble,fast and safe,and can be used in the field of secret communication and network safety.更多还原
