New digital multisignature scheme in electronic contract systems
Chang Goo Kang · 2002
The electronic contract system needs to replace hand written signatures with digital signatures, digital multisignature might also be needed in such environments where several persons might sign the same digital message. This paper analyzes risks and presents the requirements of a digital multisignature scheme in electronic contract systems. A new digital multisignature scheme suitable for contract systems is proposed and the efficiency of the scheme is discussed.
