Based on the analysis of the complexity of electronic official document system on joint mandate and the fundamental principle of proxy multi-signature,a kind of electronic document exchange system based on proxy multi-signature is desigend.According to the different requirements of security in procy multi-signature and in the process of transmission of elcetronic official document,the system adopts different security level of encryption and signature algorithm,implementing the interchanging fundation of electronic official documents which must be signed multiple departments,and the system's safety analysis proves that this system is a safety transmittal system of electronic document.
