REDACTABLE DOCUMENT SIGNATURES |
摘要 |
In one implementation, a redactable document signature system includes an encoding engine, a reordering engine, and a signature engine. The encoding engine is to access a plurality of subdocuments of a document, to generate a plurality of commitment values from the plurality of subdocuments, and to generate a plurality of dummy values. Each dummy value is indistinguishable from a commitment value. The reordering engine is to define an order of the plurality of commitment values and the plurality of dummy values independent of an order of the subdocuments. The signature engine is to calculate a signature value for the document using the plurality of commitment values and the plurality of dummy values according to the order. |
