| Abstract: | To offer a high efficiency digital signature based on elliptic curve cryptography.The design of the algorithm not only avoids time-costing inverse operation completely but also uses the hamming weight of HASH code of a message instead of HASH code itself as the message digest to participate in the signature and verifying calculation.The new scheme cost less time than the popular ECDSA.The new scheme is adapted to higher real-time needs for signature such as internet. |
