Abstract: Systems and methods relating to the encryption and decryption of messages to be sent through a communications link. The system and method uses a random data source at the receive and transmit sides, along with a trusted random sampler that produces correlated random samples from the random data source to be used at the send and receive sides. At the transmit side, the correlated random sample is used to generate a symmetric key as well as a ciphertext. The symmetric key is then used to encrypt the message. The ciphertext is transmitted, along with the encrypted message, to the receive side. The receive side then uses the ciphertext, along with its own correlated random sample, to recover the symmetric key. The symmetric key is then used to decrypt the encrypted message.
