Research of tri-unit-equivalence phenomenon and improved scheme on XTR
XTR三元素等价现象的研究及改进方案

Tri-unit-equivalence phenomenon was discussed and proved by the property of cyclic group and transposition. The effect of the phenomenon on XTR security was analyzed. A new improved scheme was proposed, and its security, computational complexity and communications cost were analyzed. The improved scheme is more effective than the others to improve the scale of XTR security.
