Title: Threshold multi-proxy multi-signature scheme based on RSA
Abstract: A new threshold multi-proxy multi-signature scheme is presented by the scheme based on aftine space RSA proposed by Chen Kefei.There is a original signature group G_0={O_1,O_2,...,O_(N1)} and aproxy signature group G_p={P_1,P_2,...,P_(N2)} in the signature scheme. T_1(T_1≤N_1)members of the original signature group can replace the original signature group to delegate a signature to proxy signature group.But any authorization by less T_1 members of the original signature group is noneffective.T_2(T_2≤N_2)members of the proxy signature group can make a effective signature.But any signature by less T_2 members of the proxy signature group is noneffective.The new scheme fully meet unforgeability and nonrepudiation and identifiability requirements.
