Artificial intelligence has always been a frequent visitor to the headlines, and Google has recently conducted an interesting test that allows AI systems to communicate with each other and try to build their own encryption system.
The main purpose of this test is to find out if the neural network can develop its own simple encryption technology to ensure that the message is not stolen by third parties. In this process, the artificial intelligence system does not need to input any specific encryption algorithm. The researchers pointed out that in theory, deep neural networks are not good at encryption.

The Google Brain team used three different deep learning neural networks in their tests, Bob, Alice, and Eve. Alice and Bob are responsible for sending and receiving messages, while Eve tries to steal and decode messages. In the experiment, Alice and Bob were entered with a predetermined set of numbers as the key for message encryption and decryption, and Eve did not finally obtain the set of keys.
Researchers who participated in this test praised its interest because the decryption method it used was not used by humans. Specifically, after completing 1500 iterations in this scenario, Alice and Bob have the ability to develop simple encryption techniques themselves. Alice successfully converted the original plaintext into ciphertext, while Bob mastered the decryption ability. For the decryption of 16-bit binary numbers, Eve can only solve 8 bits on average. Therefore, Eve's decryption is largely a matter of luck. In addition, as long as Alice and Bob update their encryption technology, Eve will fall into confusion again.
Right now, this is just a test. As for what application researchers can't think of in real life, it's amazing enough that these smart guys can learn to encrypt.
However, learning the encrypted AI will lead to a commonplace topic, whether it will threaten human security. After all, after learning to keep secret, will it keep secrets of ulterior motives?
