Abstract

For the reasons of flexibility and availability, the data may be stored in the cloud.
However security of sensitive data and the reliability of access of data are two major
issues that become immediate concern. Trust on the services for the secure upkeep of
data, its regular maintenance and mechanisms for seamless access are other issues
related to such organization of data.

In this talk, we present an encrypting file system based on GNU/Linux based
servers which can be accessed through standard protocols such as NFS over
unsecured networks. At the same time, the data stored in the servers is always in
encrypted form. With only a suitable key management protocol and access control
mechanisms, it is ensured that data is made available only to right entities. In the
trusted domain for the files, even the system administrators are not included which
makes it highly robust yet providing mechanisms for routine administrative jobs such
as backup, restoration, duplication and other similar functions on data.

We also present a few more applications for this same file system, such as the case
where data on a portable device such as laptop can be protected against loss of
information in case of thefts etc.
