Our Secure Grid Filesystem has been developed based on two core building-block technologies. One is SFS (Self-certifying File System), the other is GSI (Grid Security Infrastructure). Please refer to Biogrid Project about GSI-SFS.
Until now, GSI-SFS was not a product supporting next-generation IPv6 network.
IPv4 network has a serious problem of depletion of address. On IPv4 network,
It has only 2^32 addresses. On the other hand, it is possible to assign 2^128
addresses on IPv6 network.
Thus we developed GSI-SFS for IPv6.
Figure 1: The structure of GSI-SFS
We implemented a prototype by creating GSI server (GSI-SFS Key Server)
and client (GSI-SFS Key Client) which are independent from SFS. The whole
system including GSI, SFS and GSI-SFS Key Server/Client is named GSI-SFS.

GSI-SFS performs various communications among a number of modules. However,
communication via network is performed only in two pares of modules. They
are a server/client pare of GSI authentication modules and a pare of SFS
data transfer modules. The GSI authentication modules have been originally
designed for IPv4/IPv6 dual stack, therefore we modified the SFS data
transfer modules to make the whole system IPv6 aware.
