This paper addresses the problem of constructing secure exact-repairregenerating codes at the MSR point for all feasible values of the parameters.The setting involves a passive eavesdropper who is allowed to observe thestored contents of, and the downloads into, an $l$-subset of the $n$ nodes of adistributed storage system (DSS). The objective is to achieve perfect secrecybetween the eavesdropped symbols and the file stored on the DSS. Previoussecure code constructions (most notably that by Rawat et al.) tackle theproblem only for the restricted case wherein the number, $d$, of helper nodesaiding in the recovery of a failed node is equal to $n-1$. This paper builds onRawat's work, by combining Gabidulin pre-coding and an MSR construction by Yeand Barg to prove the achievability of secrecy capacity at the MSR point forall allowed values of $d$.
