An ElGamal_type(t,n)Threshold Digital Signature Scheme Based on ECC |
| |
| Abstract: | This paper comprehensively introduces and analyzes Shamir Secret Sharing, Pedersen's Verifiable SecretSharing based on ECC, verifiable secret sharing without a trusted center based on ECC and an ElGamal digital signa-ture scheme based on ECC. Based on the theoretical introduction, an ElGamal_type(t, n) threshold digital signaturescheme Based on ECC is designed. The performance of the scheme is analyzed. And an application based on thescheme is described. In the scheme, a trusted center to deal with the sharing secret is eliminated. No secret communi-cation is required in the signature issuing phase. The scheme is characterized by excellent security as well as high effi-ciency. |
