| Abstract: | On the basis of the digital signature system model based on elliptic curve,an improved digital signature algorithm is proposed.The algorithm greatly enhances execution efficiency by eliminating modular inverse operation which influences the efficiency of digital signature.Moreover,the identification mechanism is added in the signature scheme model,it ensures data transmission security and prevents forged signature.The improved signature model is of certain practical value. |
