Abstract: This paper presents a new type of signature, contract digital signature, based on Discrete Logarithm(DL) and Elliptic Curve(EC) cryptosystems. Contract signature is similar to a real-life contract. No less than two signers take part in a contract signature. After introducing the concept and definition of contract signature, a scheme based on Discrete Logarithm (DL) and Elliptic Curve (EC) cryptosystems is presented. This scheme allows signers, whose ordinary signature schemes use many different cryptographic systems, to generate a single signature. The scheme requires neither a trusted arbitrator nor a high degree of interaction between signers. We then prove that this scheme is secure under the discrete logarithm assumption.
