In the history of document circulation, many participants may annotate and sign on the document so as to produce a final authentic document. This circulation process requires that a later participant can know the document circulation history, verify all the previous annotations, but can not modify them. To be applicable to devices of limited resources, the document processing approach should be efficient in terms of computational cost and network overhead. This paper extends an aggregate signature scheme so as to combine many signatures into one no matter which kind of circulating route (sequential, parallel, or hybrid) is. Since the proposal enables to manage the documents easily, it is useful and practical in office automation applications.
