Very long term protection
The advanced signature standards (CAdES-A and XAdES-A) define all the necessary information to securely revalidate signature during long duration. A validation server like Serenity can extend the lifetime of advanced signatures... but if you need performances and batch processing, Perennity is made for you.
Efficiency and batch processing
Cryptolog developed Perennity to meet the requirement of maintaining a great deal of archives after a very long time, by regularly processing the signatures as long as necessary.
The main assets of Perennity are its amazing performances and the use of a unique timestamping token for many archives. Different timestamping authorities can be used anytime to guarantee a constant availability of a correct time.
Perennity is more efficient than Serenity, you do not have to bother about what to do: send your archives to Perennity, he will check whether they need to be processed or not.
Perennity is the answer to mass long-term archiving: let him keep your archives ready to be validated again and again.
