Details of the hypergraph:
Center node: "learning to protect communications with adversarial neural cryptography"
  Abstract: We ask whether neural networks can learn to use secret keys to protect#N#information from other neural networks.  Specifically, we focus on#N#ensuring confidentiality properties in a multiagent system, and we#N#specify those properties in terms of an adversary.  Thus, a#N#system may consist of neural networks named Alice and Bob, and we aim#N#to limit what a third neural network named Eve learns from#N#eavesdropping on the communication between Alice and Bob.#N#We do not prescribe specific cryptographic algorithms to these neural networks;#N#instead, we train end-to-end, adversarially.#N#We demonstrate that the neural networks can learn #N#how to perform forms of encryption and decryption, and also#N#how to apply these operations selectively in order to meet#N#confidentiality goals.
