A General Threshold Signature Scheme Based on Elliptic Curve
Based on Elliptic Curve cryptosystem,a threshold signature scheme characterized by (k,l) joint verification for (t,n) signature is put forward.After being signed by a signer company employing (t,n) threshold signature scheme,the information m is transmitted to a particular verifier company,and then the signature is verified through the cooperation of k ones from the verifier company with l members,so as to realize a directional transmission between different companies.Finally,the application examples of the company cncryption communication system,the generating polynomial of company private key and public key were given.The security of this scheme is based on Shamir threshold scheme and Elliptic Curve system,and due to the advantages of Elliptic Curve,the scheme enjoys wider application in practice.
