基于ECC&AES混合加密应用系统原创

对称密码技术高级加密标准算法(AES)易于软件实现和硬件实现，并且具有加密速度快、内存消耗小、抵抗多种人为攻击、操作简单等优越性。非对称密码技术椭圆曲线加密(ECC)是基于离散对数难题的，这使得对于相同长度的密钥来说， ECC加密更快、破解难度更大。 本文实现了128位密钥的AES算法，将原来的四步加密过程整合为两步，通过CBC或ECB两种分组模式加密明文数据。同时也实现了在大素数域上的ECC算法，利用ECC实现生成用户公钥、私钥以及加密数据的高效、安全密钥管理机制。 通过将AES算法和ECC算法结合起来，实现混合加密，并应用在文件管理上体现其价值。该系统内文件加密过程利用的是AES算法加密模块，在管理用户密钥方面利用了ECC算法加密模块，并实现多重加密来隐藏直接加密后密文内的重要参数。该系统可以安全、有序的管理用户拥有的重要文件。
