資源簡介

對稱密碼技術(shù)高級加密標(biāo)準(zhǔn)算法(AES)易于軟件實(shí)現(xiàn)和硬件實(shí)現(xiàn)，并且具有加密速度快、內(nèi)存消耗小、抵抗多種人為攻擊、操作簡單等優(yōu)越性。非對稱密碼技術(shù)橢圓曲線加密(ECC)是基于離散對數(shù)難題的，這使得對于相同長度的密鑰來說， ECC加密更快、破解難度更大。 本文實(shí)現(xiàn)了128位密鑰的AES算法，將原來的四步加密過程整合為兩步，通過CBC或ECB兩種分組模式加密明文數(shù)據(jù)。同時也實(shí)現(xiàn)了在大素數(shù)域上的ECC算法，利用ECC實(shí)現(xiàn)生成用戶公鑰、私鑰以及加密數(shù)據(jù)的高效、安全密鑰管理機(jī)制。 通過將AES算法和ECC算法結(jié)合起來，實(shí)現(xiàn)混合加密，并應(yīng)用在文件管理上體現(xiàn)其價值。該系統(tǒng)內(nèi)文件加密過程利用的是AES算法加密模塊，在管理用戶密鑰方面利用了ECC算法加密模塊，并實(shí)現(xiàn)多重加密來隱藏直接加密后密文內(nèi)的重要參數(shù)。該系統(tǒng)可以安全、有序的管理用戶擁有的重要文件。
