The problem of exact-repair regenerating codes against eavesdropping attack is studied. The eavesdropping model we consider is that the eavesdropper has the capability to observe the data involved in the repair of a subset of

nodes. An

secure exact-repair regenerating code is an

exact-repair regenerating code that is secure under this eavesdropping model. It has been shown that for some parameters

, the associated optimal storage-bandwidth tradeoff curve, which has one corner point, can be determined. The focus of this paper is on characterizing such parameters. We establish a lower bound

on the number of wiretap nodes, and show that this bound is tight for the case
