War With the rumor of a non-aggression pact between Nazi Germany and the Soviet Union circling the globe, the United States created a strict intelligence campaign known as the Venona Program to monitor Soviet diplomatic actions. Decryption of what was thought to be Soviet diplomatic messages revealed an extensive Soviet espionage network that was functioning within the United States. We will write a custom essay sample on The U. Unfortunately, the success of the Venona Program was undermined by the United States lack of internal security, as Soviet agents rose into the high ranks of both the United States government and global military research divisions unchecked.
The following are the remarks made by Mr. Crowell retired from NSA on 12 September For over an hour Frank told us stories about the successful exploitation of codes and ciphers during the war. He spoke about how those successes had helped U.
But, he was very careful to avoid claiming that cryptography had won any battles. That distinction — between providing information that can make a difference — and using information to make a difference is still an important one and certainly applies to the results that were achieved in the successful breaking of the codes and ciphers known as VENONA Twelve years later I was assigned as a manager in an NSA division that included the VENONA project.
In a very short time I came to appreciate that VENONA was an absolutely fascinating story of the personal determination and dedication of a small group of cryptanalysts. It was, in addition, a brilliantly intellectual cryptanalysis effort.
I also realized it was a story of considerable historical moment and that someday, when the need and responsibility to protect the sources and methods involved was diminished, it would be made public.
But, as we make this release, I think it is most appropriate that we recognize the extraordinary people who did the work. The story of the efforts to attack Soviet KGB and GRU traffic began in February when a young woman, Miss Gene Grabeel, was assigned to organize, characterize, and analyze thousands of encrypted Soviet diplomatic messages.
Through nearly a decade following, a number of analysts, by dint of their dogged determination, slowly made headway against a family of extremely sophisticated, double-encrypted cryptographic systems.
They painstakingly extracted information, a word or two at a time, from one of the most challenging systems that had ever been exploited.
The first and most significant breakthroughs against the VENONA cryptosystems were made without even the most rudimentary computers or other sophisticated tools which we are accustomed to using today.
While the Soviet traffic that was ultimately read under the VENONA project spanned the yearsefforts to exploit it continued for decades. This was due to the agonizingly slow and difficult process in which sometimes only one or two words at a time were wrenched grudgingly from the code.
Each new recovery came with the elation akin to finding a pearl in an oyster. But each recovery also led to renewed work as each message had to be reviewed to see if that code group was present and, if it was, then the enlarged context was checked and scrutinized to see if it provided clues to other unrecovered code groups.
Similarly, as counterintelligence information based on the decrypts was passed to the FBI and the FBI investigated the leads, new information was developed which sometimes enabled new breaks into the code. Then the process would begin all over again. People continued to work on VENONA so long as the possibility remained that counterintelligence information might be developed that could possibly reveal new agents or espionage activities that might still be active.
When it was no longer reasonable to expect that those named in might still be alive or active in an espionage role, then ongoing efforts to continue to break the VENONA cryptosystems was terminated.
Richard Leibler, just to name a few. They and their colleagues brought a fearsome intellectual firepower to bear on various aspects of the VENONA puzzle with astounding, but hard won success. First and foremost was the cooperation between the intelligence and law enforcement communities.
There is no clearer example of synergism in the early days than these cooperative relationships. They consisted of a code book in which letters, words, and phrases were equated to numbers.
So a code clerk would take a plain text message and encode the message using numbers from the codebook. This would have presented a significant challenge itself depending on how long the code book was used. However, the messages were further modified, in other words double-encrypted, by use of a one time pad.
The use of a one time pad effectively randomizes the code and renders it unreadable. The key to the VENONA success was that mistakes were made in the construction and use of the one time pads — a fact that was discovered only through brute force and analysis of the message traffic.
Once sufficient breakthroughs had occurred, it became clear that the Soviet diplomatic traffic was encrypted in several similar systems and that it included KGB and GRU espionage traffic in addition to diplomatic and trade messages.The Venona project was a counterintelligence program initiated by the United States Army's Signal Intelligence Service (later the National Security Agency) that ran from February 1, .
However, the true success of the United States intelligence program is only seen through close scrutiny of its counter-intelligence program. As the events of World War II became increasingly volatile, a fear was growing in the United States State as well as War Department that an alliance between Nazi Germany and the Soviets would allow the Axis (Germany, Italy, and Japan) to focus its attacks solely on the U.
Unfortunately, the success of the Venona Program was undermined by the United States lack of internal security, as Soviet agents rose into the high ranks of both the United States government and global military research divisions unchecked.
Army's Signal Intelligence Service, the precursor to the National Security Agency, began a secret program in February later codenamed VENONA. The mission of this small program was to examine and exploit Soviet diplomatic communications but after the program began, the message traffic included espionage efforts as well.
