摘要：Information provenance is a new research field that can be used to determine the source, quality and reliability of the Information. We focus on the unique security needs of the provenance information in electronic commerce and study regrowth method of broadcast encryption tree for the insufficiencies of encryption scheme of information provenance. We propose a new security provenance model with the introduction of time-stamp technology in order to increase the security of signatures which protect the security of provenance information. © 2013 Asian Network for Scientific Information.
