基于SM9數(shù)字簽名算法的應(yīng)用研究摘要

SM9數(shù)字簽名算法是一種由國家密碼管理局制定的基于橢圓曲線密碼理論的簽名算法，具有安全性高、性能好、可擴(kuò)展性強(qiáng)等優(yōu)點(diǎn)，因而被廣泛應(yīng)用于電子商務(wù)、電子政務(wù)、數(shù)字認(rèn)證等領(lǐng)域。本文首先對SM9數(shù)字簽名算法的基本原理及特點(diǎn)進(jìn)行了詳細(xì)介紹，接著針對SM9簽名算法在應(yīng)用中可能遇到的問題進(jìn)行了分析與解決，包括簽名效率低、證書管理等。然后，以國家稅務(wù)總局?jǐn)?shù)字稅務(wù)局為例，探討了SM9數(shù)字簽名算法在數(shù)字稅務(wù)領(lǐng)域的應(yīng)用。最后，總結(jié)了SM9數(shù)字簽名算法的優(yōu)劣勢，并展望了該算法在未來的發(fā)展趨勢。
