摘　　要：可信密码模块(TCM)是可信计算密码支撑平台的关键基础部件。给出了一种TCM中SM2引擎的设计架构,完成了模运算和椭圆曲线点乘运算的IP设计与高效实现,定义了固件应用接口,并以ELGamal体制为例完成了固件程序开发。基于两种器件工艺完成了IP设计的优化综合,结果表明与同类设计相比,在牺牲不多硬件资源的前提下,该设计运算性能有较大的提高,可集成于TCM中发挥SM2引擎的功效。Trusted cryptographic module（TCM） is the fundamental component of cryptographic support platform for trusted computing.System architecture of SM2 engine in TCM is proposed,IP design and efficient implementation of the architecture is given.The application interfaces are defined for top-level usage,and with ELGamal cryptography as an example,the firmware is developed.Based on two device technologies,the optimized synthesis of IP design is achieved.As compared with other designs,this design is of higher computing performance at the expense of small quantity of hardware resource,and could be integrated in TCM and serve as SM2 engine.
