We consider distributed storage over two untrusted
networks, whereby coding is used as a means to achieve a
prescribed level of confidentiality. The key idea is to exploit the
algebraic structure of the Vandermonde matrix to mix the input
blocks, before they are stored in different locations. The proposed
scheme ensures that eavesdroppers with access to only one of
the networks are unable to decode any symbol even if they are
capable of guessing some of the missing blocks. Informationtheoretic
techniques allow us to quantify the achievable level
of confidentiality. Moreover, the proposed approach is shown to
offer low complexity and optimal rate.
