A computer system for authenticating, encrypting, and transmitting a secret communication, where the encryption key is transmitted along with the encrypted message, is disclosed. In an embodiment, a first transmitting processor encrypts a plaintext message to a ciphertext message using a data key, encrypts the data key using a key encrypting key, and sends a communication comprising the encrypted data key and the ciphertext message. A second receiving processor receives the communication and then decrypts the encrypted data key using the key encrypting key and decrypts the ciphertext message using the data key to recover the plaintext message.
