By design, because of the time as needed, secure this has received valuable digital document is signed. This ensures that it is readily accessible when all the data is stored may consistency, it is needed. We can do that either way has a presence, the possible presence of accessibility document destruction or document for a period of maintenance specific as well as his integrity together with authenticity and integrity of digital documents it through the save. This protocol was offered to use the role of being developed by the IETF (Internet Engineering Task Force) or TAA (institution records trusted) kind to operate.
Task of PKI is that the document that have different responsibilities for a while TAA to legality and non- refoulement is the possible ways, to secure the signature of reliability, the provision of an electronic document. Data point is operated in order to ensure that the presence of legal, guaranteed when necessary and can be used, the consistency and reliability which is as effective as integrity. Then, to preserve the valuable specific data coming, the LTAP acting to establish a long-term guarantee. (more…)
