Encryption isn’t a new thing as people have been using it to protect their online privacy. However, American whistleblower Edward Snowden has offered a new idea about encryption. He said the detection of signals sent from aliens could be difficult because of the security measure.
Snowden thoughts about the encryption and foreign signals were made during an interview with science communicator and astrophysicist Neil deGrasse Tyson on the StarTalk podcast.
Snowden was communicating from Moscow through a beam remote presence system, which is a robot video link. The whistleblower managed to control the robot from Russia. He rolled straight into the office of Tyson at the Hayden Planetarium in New York.
Tyson asked Snowden on the possibility of alien civilizations communicating with encrypted messages. Snowden answered that most advanced societies may have been encrypting their communications, and it may be the reason humanity never heard from other civilizations. Snowden went on to say that there’s no real method to determine encrypted messages in a properly encrypted communication.
Snowden became famous after leaking classified U.S. documents involving secret mass surveillance program. Washington charged him with espionage and theft, and Russia granted him asylum.
