SM3 算法在导弹数据数字化登记系统中的应用

为解决目前部队在导弹数据记录、存储中经常出现的数据篡改、描涂、字迹不清等问题，设计一种基于Hash 函数的导弹数据数字化登记系统。介绍 Hash 函数验证数据完整性的原理，对比几种常用的 Hash 函数，介绍我国自主研发的 SM3 算法，对其实现效率进行改进，设计导弹数据完整性验证方案，并使用 C#语言进行导弹数据数字化登记系统的开发。测试结果表明：该系统能有效检验数据是否完整，且具有可行性与可推广性。

Application of SM3 Algorithm in the Digital Registration of Missile Data

In order to solve these problems such as data tampering, tracing and handwriting is not clear that often occurin the missile data recording and storage, to design a digital data registration system of missile based on Hash function.This paper introduces the principle of Hash function validation data integrity, compares of several common Hash functions,describes SM3 algorithm which designs by our country, improve the efficiency of its implementation, design missile dataintegrity verification plan, and use C # language to research and develop the missile data digital registration system. Thetest results show that the system can effectively test data integrity, and has the feasibility and extension.
