摘要
本文给出ｎ维ｍ值随机变量特征函数的定义，讨论了它的性质，给出了异于实数域上随机变量序列的特征函数收敛性定理，并得到了对密码设计与密码分析有意义的有限个ｍ值随机变量和是均匀分布的充要条件。
おn this paper,the characteristic function of mvalued random variable with n dimersons is defined and its convergent theorem which is different from that on the real field is obtained.A necessary and sufficient condition under which a finite sum of independent mvalued variables is uniform distribution is obtainel.
