Center node: "toward optimal secure distributed storage systems with exact repair"
  Abstract: Distributed storage systems (DSSs) in the presence of an external wiretapper are considered. A DSS is parameterized by    $(n, k, d)$   , in which the data are stored across    $n$    nodes (each with storage capacity    $\alpha $   ), and must be recoverable by accessing the contents stored on any    $k$    out of    $n$    nodes. If a node fails, any    $d \geq k$    out of    $(n-1)$    nodes help in the repair (regeneration) of the failed node (by sending    $d\beta $    units of repair data, where    $\beta \leq \alpha $   ), so that the data can still be recovered from the DSS. For such a    $(n, k, d)$   -DSS, security from the two types of wiretappers is investigated: 1) Type-I (node data) wiretapper, which can read the data stored on any    $\ell    nodes and 2) Type-II (repair data) wiretapper, which can read the data that is used to repair a set of    $\ell $    failed nodes. The focus of this paper is on the optimal tradeoff between the storage    $(\alpha )$    and the repair bandwidth    $(d\beta )$    in presence of a Type-I/Type-II wiretapper and the practically relevant constraint of exact repair in which a failed node must be replaced by its exact replica. In this paper, several new results and outer bounds for the storage-versus-exact-repair-bandwidth tradeoff(s) are obtained for the Type-I and Type-II security problems. Furthermore, new outer bounds are presented for the Type-II problem, which hold for general    $(n, k, d,\ell )$    parameters. It is shown that these outer bounds strictly improve upon the existing cutset-based outer bounds. The key technical contribution of this paper is in developing novel information theoretic converse proofs for these problems. From our optimal characterization results, we show that in a Type-II setting, the only efficient point in the storage-versus-exact-repair-bandwidth tradeoff is the minimum bandwidth regenerating (MBR) point corresponding to    $\alpha =d\beta $   . This is in sharp contrast to the Type-I setting in which the optimal tradeoff allows a spectrum of operating points beyond the MBR point.
