| Abstract: | Based on ECC and ElGamal digital signature scheme, an ElGamal-type threshold digital signature scheme based on ECC is designed. The security of the scheme is analyzed via introducing the concept of views. In this scheme, the trusted center to deal with the sharing secret is eliminated. No secret communication is required in the signature-issuing phase. The scheme is characterized by excellentsecurity as well as high efficiency. |
