摘要
设计了一种基于椭圆曲线密码的数字签名方案.与ECDSA签名方案相比,该方案从密钥产生到签名、验证整个过程中都没有使用最费时的求逆运算,并且采用Hash函数的汉明重量代替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.
A digital signature scheme is presented based on elliptic curve cryptograph. Combined with the well-known scheme ECDSA, the design of the presented scheme has no time waste inverse operation through all the process, from key producing, signature calculation to verifying calculation, and use the hamming weight of Hash code of a message instead of Hash code itself to participate in the signature and verifying calculation, which can improve the computation efficiency. This design can be used to meet the higher real-time needs.
