A secure and efficient directed threshold signature scheme
Zhonghua Shen · Journal of Zhejiang University(Science Edition) · 2006
The signature on the message should be that only the signature receiver can verify the signature and prove the validity of the signature to any third party.The validity of signature without his cooperation is checked.In most situations,the signer is generally a single person.However,when the message is written on behalf of an organization,a valid message may require the approval or consent of several people.Threshold signature is a solution to this problem.Generally speaking,as an authority which can be trusted by all members doesnt exist,a threshold signature scheme without a trusted party appears more attractive.A directed threshold signature scheme is proposed.
