Abstract :
For the original article see ibid., vol. 28, p. 1015-17 (1992). The commenters show that even though the improved ID-based key sharing system, proposed by T. Chikazawa and A. Yamagishi in the aforementioned paper, can resist the SK attack, the improved scheme as well as the original scheme can be completely broken by the conspiracy of (n+1) entities with overwhelming probability
