Any thoughts on the final line of this refers to?<p><i>AUTHENTICATED CRYPTOGRAPHY PATENT NO.: 7,827,408</i><p><i>Message encryption and authentication are typically performed separately. In other words,
a message is encrypted using one method and then a cryptographic hash of the message is generated
using a second method.
This invention is a device for and method of encrypting and authenticating a message and authenticating any additional
information. The present invention provides a cryptographically stronger authentication method and is more efficient to implement, than the prior art.</i><p><i>VALUE:
Provides combined authenticated encryption in efficient manner. Does not require random numbers, two encryption keys, or checksums.</i>
