设计了一种改进的高效数字签名算法,与数字签名算法(DSA)相比,该方案从参数选择、签名算法生成、验证算法的整个过程中没有使用复杂费时的求逆运算,并且运用Hamming重量及MD5算法代替Hash函数本身参与签名和验证的计算,提高了运算效率,适用于实时性要求较高的场合.
An improved efficient digital signature algorithm was designed.Compared to the Digital Signature Algorithm(DSA).The complex and time-consuming inverse operation was not used in the parameter selection,signature algorithm and authentication algorithm during the whole process.Hamming weight and MD5 algorithm instead of Hash function itself were used in the signing and verifying calculation,which can improve the operational efficiency and be suitable for real-time applications.
