Practical cryptanalysis has even been acknowledged at the highest level. The source is none other than Nikita Sergeyevitch Khrushchev. While sightseeing in Los Angeles with U.S. Ambassador to the U.N. Henry Cabot Lodge during his 1959 visit to the United States, the Soviet Premier boasted that he had seen a message that President Eisenhower had sent to Prime Minister Nehru of India about border troubles with Red China, as well as a message to Eisenhower from the Shah of Iran. Earlier, in Washington, he remarked to C.I.A. chief Allen Dulles that C.I.A. agents gave their codebooks to the Russians, which the Soviets used to feed false information to the C.I.A. and to demand and receive money. He suggested that the U.S. and the U.S.S.R. save money by pooling intelligence services.
