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.
