自从在战争中使用无线电通信以后,通信联络迅速、准确的目的是达到了,可是无线泄密问题随之而来,泄密与反泄密的斗争越来越激烈。到了近代,世界各国军队为了防止敌方破译无线电密码,纷纷研制出了投资规模达上千万元的防破译设备,其代价极为高昂。但是,谁曾料想到,早在无线电用于战争的初期,就有人用一种十分简单廉价而又奇特的密码解决了反破译问题。第一次世界大战烽火四起后,美军发往各野战前线的密令和密码经常被狡猾的德军破译,使美军的行动企图常常难以实现,有时还要遭受很大的损失。对此,美军恼火极了。后来,美军中一个叫霍尔涅尔的 Since the use of radiocommunication in the war, the rapid and accurate communication has been reached. However, the issue of wireless leaks has followed. The fight between leaks and anti-leaks has become increasingly fierce. In the modern era, in order to prevent the enemy from deciphering the radio code, the armed forces of various countries in the world have successively developed anti-deciphering equipment with a total investment of 10 million yuan, which is extremely expensive. However, one had come to expect that early in the war for radio, someone solved the anti-deciphering issue with a very simple and cheap password. After the war in World War I, the secrets and passwords sent by the U.S. military to the frontlines of various fields were often deciphered by the cunning German army, which often made the U.S. military's attempt at operations difficult and sometimes suffered a great deal. In this regard, the U.S. military is extremely angry. Later, one of the U.S. troops named Hornier
