【摘要】：针对现有密码处理器存在的问题,借鉴流处理器架构,提出了高效能的可重构分组密码流处理器架构.该架构采用层次化设计思想,通过分块式本地寄存器组的数据组织方式和共享拼接使用运算单元机制,实现了软件流水和硬件流水的协同工作,能够挖掘分组内和分组间的指令级并行性并提高功能单元的利用率.在65nm CMOS工艺下对架构进行了综合仿真,并经过了大量算法映射.实验结果证明,该架构在CBC和ECB加密模式下均具有良好的加密性能.与其他密码处理器相比,该架构具有小面积、高效能的特点.
[Abstract]:Aiming at the problems existing in the existing cryptographic processors, a high performance reconfigurable block cipher stream processor architecture is proposed based on the stream processor architecture.The architecture adopts the idea of hierarchical design, through the data organization mode of block local register group and the operation unit mechanism of shared splicing, the cooperative work of software income and hardware income is realized.It can mine instruction-level parallelism within and between packets and improve the utilization of functional units.The architecture is simulated in 65nm CMOS technology, and a large number of algorithms are mapped.Experimental results show that the architecture has good encryption performance in both CBC and ECB encryption modes.Compared with other cryptographic processors, the architecture has the characteristics of small area and high performance.
