Abstract:
1. A method comprising: providing a first network device and a second network device of a data network, each of the first network device and the second network device having a decoy cryptographic key and an authentic cryptographic key, wherein the decoy cryptographic key is used to detect unauthorized data being transmitted in the data network, wherein the authentic cryptographic key is used to encrypt authorized data being transmitted in the data network, wherein providing the first network device and the second network device comprises, for each of the first network device and the second network device: receiving, by the first network device, data from the second network device, wherein the data is encrypted using the decoy cryptographic key; determining, by the first network device, that the data is encrypted using the decoy cryptographic key by determining that the authentic cryptographic key cannot be used to decrypt the data and decrypting the data using the decoy cryptographic key; and discarding, by the first network device, the data encrypted using the decoy cryptographic key.
