摘要: In this paper, we shall propose a threshold multi-proxy multi-signature scheme with shared verification. In the scheme allows the group of original signers to delegate the signing capability to the designated group of proxy signers. Furthermore, a subset of verifiers in the designated verifier group can authenticate the proxy signature. A threshold multi-proxy multi-signature scheme with the non-repudiation property is a scheme where the proxy group cannot deny signing for the message and the verifier group can identify the proxy group for a proxy signature.
