Trojan线路

The "Trojan Lines" refer to a method of secret communication employed by the Soviet Union during the Cold War. This strategy was designed to prevent espionage and maintain secure communication between the Soviet Union and other countries. The lines were encrypted using a cipher known as the Vigenère cipher, which involved shifting letters in the message by a set number of positions in the alphabet. This cipher was used to encode messages, making them difficult to intercept without the correct keys. The lines were spread across various countries and were used to communicate sensitive information, such as intelligence and military plans. However, the lines were eventually exposed and exposed under the cover of Soviet forces, ending the secretiveness of this communication method.
