Abstract
Directed signature is introduced when the signed message contains privacy which is sensitive to the receiver, it is widely used in some special occasions involving signature privacy, such as electronic bidding, electronic voting, personal business activities, etc. This paper presents a new directed proxy multisignature scheme, which integrated the directed signature and proxy multisignature. In the proposed scheme, the agent generate a signature on behalf of the delegators, only a receiver specified by the delegator convince whether the truth of signature or not. At last, we analyze the characteristics and discuss the security of the scheme.
