Security

Information security and cryptography are cornerstones of the information society.
In fact, strong security mechanisms are needed to implement functions such as
the integrity of financial transactions, the accountability for electronic signatures,
the confidentiality within a virtual enterprise, the privacy of personal information,
or the availability of the critical infrastructure.

With the growing amount of information stored, the importance of stored data
to individuals, companies and governments is also increasing. In addition to the
traditional criteria such as performance, capacity, and reliability, security
is quickly becoming an important feature of storage systems. Storage space is
typically provided by complex networked systems, where clients communicate directly
with a disk over a network as in network-attached storage (NAS) or in storage-area
networks (SANs).
We are currently investigating and implementing secure multilayer access
restrictions and cryptographic techniques to defend data in flight and data
at rest.
