Abstract: Data diode systems and methods are disclosed herein for enhancing data security. Encrypted data transmitted from a first node (e.g., an entity coupled to a network) is received. The data transmitted is encrypted with a public key associated with a second node (e.g., the node to which to which the encrypted data is transmitted). The encrypted data is decrypted with a private key associated with the second node to generate decrypted data. A determination is made whether a digital signature in the decrypted data corresponds to a ledger entry mapped to the first node in a first set of ledger entries. The first node is verified to be a trusted entity based on the digital signature having been determined to correspond to the ledger entry. Based on the verification, the transmission of the encrypted data from the first node is determined to be a permissible data transmission.
