Abstract: Data may be protected using a combination of symmetric and asymmetric cryptography. A symmetric key may be generated and the data may be encrypted with the symmetric key. The symmetric key and a only a portion of the symmetrically encrypted data may then be encrypted with an asymmetric public key. The entire set of encrypted data, including the asymmetrically encrypted symmetric key, the doubly encrypted portion of data, and the remainder of the symmetrically encrypted data may then be sent to a remote device using insecure communications.
