Our new paper “On the tradeoff region of secure exact-repair regenerating codes,” by S. Shao, T. Liu, C. Tian, and C. Shen, was published in IEEE Trans. Inform. Theory, Vol. 63, No. 11, pp. 7253-7266, Nov. 2017. We provide a clearer picture on the geometry of the tradeoff region of secure exact-repair regenerating codes. Past results appeared to suggest that the tradeoff region has only one corner point, however, we show that this is only true for more stringent security requirements, but not so for less stringent parameter settings.
