The multi signature is a form of group-orientated cryptography that became first added with the aid of using Desmedt in 1987. The group has a protection coverage that calls for a multi signature to be signed with the aid of using all institution individuals with the understanding of more than one non-public key. However, to any verifier, the multi signature may be established the use of a corresponding institution public key. In general, we expect that everyone organization participants do now not take delivery of as real with each other. On the opposite hand, in the event that they do accept as true with every other, all non-public keys may be shared amongst themselves. In this paper, we proposed new proxy-multi signature scheme primarily based on DLP. We display that our new scheme can withstand existential forgeries in opposition to adaptive chosen-message attacks. Furthermore, the brand new scheme is quite simple and efficient computationally. It has the belongings that the dimension of a multi-signature is unbiased of the variety of the authentic signers. In addition, this proxy- multi signature can be used for suitable type of block-chain structure.
