SIGINT or Signals intelligence is intelligence-gathering by interception of signals, whether communications between people COMINT or communications intelligence or from electronic signals not directly used in communication ELINT or electronic intelligence.

As sensitive information is often encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signalling whom and in what quantity—is also used to derive information.[1]

Zimmermann Telegram

Intel Today reports:

On 16 January 1917, British code breakers intercepted an encrypted message from German foreign secretary Arthur Zimmermann intended for Heinrich von Eckardt, the German ambassador to Mexico. The decryption of the Zimmermann Telegram is widely described as the most significant intelligence triumph for Britain during World War I. The story demonstrates that SIGINT can influence the course of History.[2]
