Future Work
Most of the browsers and proxies in use today do not impose the 256 character limit on
URL size. With this limit lifted a fixed table of servers is no longer needed as the Publius
URL itself can contain the IP addresses of the servers on which the content is stored. With no predefined URL size limit there is essentially no limit to
the number of hosting servers that can be stored in the Publius URL. The Publius URL structure remains essentially the same - just the
IP addresses are added. The option and namei components of the URL remain as
they are still needed for tamper checking and URL interpretation. We intend to
use this URL format in future versions of Publius.
During the Publius publication process the encrypted file, along with other information,
is stored on the host servers. Krawczyk in [14] describes how to use Rabin's
information dispersal algorithm to reduce the size of the encrypted file stored on
the host server. We are planning to use this technique to reduce amount
of storage needed on host servers.
