Abstract: Systems and methods of correcting errors in encrypted communication between a server and client devices using keyless encryption schemes are disclosed. Client devices with arrays of physical-unclonable-function devices respond to challenges from a server. Characteristics of the arrays are stored by the server during a secure enrollment process. To send an encrypted message, the server generates a message digest, extracts data from the stored arrays on the basis of the message digest, applies error correction codes to the message, encrypts the message with the extracted data, and sends the message to a client. The server may receive a handshake containing all or part of the message digest, measures its PUF, and decrypts and decodes the message.
