Wow I didn't know you could be awarded a patent for "A device for providing secure communications over a network" in 2005. I'm fairly certain secure network communication devices were around long before the filing (2002) or approval date of this patent.
Additionally Private/public key has been around since 1976, and this was filed for in 1999 and is essentially what their patent describes.
Stating that they had been doing it for 30 years seems meaningless, since these were patented nearly 40 years ago.
