摘要: A method for proving the validity of a record digitally signed by user having digital certificate issued certification authority within hierarchy authorities. The signs (502), and obtains certificates revocation information all authorities in chain extending from to root authority. timestamp is applied (506), establish point time which items were created, current valid. If, at some later point, one or more either expire are revoked, serves as evidence integrity record.
