I believe it's just a guess based on fit.
Suppose I'm the manager writing this document, reporting the expected accomplishments of my group. We do cryptanalysis. If we're projecting success against FooBarCo chips' encryption sub-core, and everybody knows FooBarCo chips are used in both encryption and non-encryption products, it makes sense to cite the specific applications where FooBarCo chips are used. So "for FooBarCo chips used in VPN and SSL" makes sense, even if FooBarCo chips are not *solely* VPN and SSL. However, in "for FooBarCo encryption chips used in VPN", the "encryption" seems to me to denote a special purpose chip, rather than a general purpose chip with an encryption sub-core. I've seen worse manglings of language in similar documents, though, so I would not put it past said middle manager to write "for Intel Ivy Bridge encryption chips used in VPN and SSL", even though that's a bit of word salad to anyone who knows the technology.
"Cavium Networks" or "Cavium Nitrox" are approximately the right length to fit. Other vendors that might be interesting include F5, Barracuda, Riverbed, Cisco SCA 11000, Radware (an Israeli/American company), and everybody listed on http://en.wikipedia.org/wiki/SSL_Acceleration The document looks like Word and appears to be fully justified; anyone with that software want to match the fonts and try out various substitutions to see what fits best? Note that http://s3.documentcloud.org/documents/784159/sigintenabling-clean-1.pdf seems to have been digitally processed and redacted; the font baselines are perfectly aligned, to the sub-pixel antialiasing limit; while http://s3.documentcloud.org/documents/784280/sigint-enabling-project.pdf appears to have gone out to paper and then been scanned in on a non-flatbed scanner; there is significant vertical slew across the line of text in question. Since the source document appears to be the same for both, an enterprising DTP jockey could use -clean-1.pdf to tune the document settings precisely, and then use -project.pdf to search for better unredaction matches. -andy

i see your skepticism, and i raise you a retort! ;) i even have a list of candidates you can experiment with to confirm Intel Ivy Bridge as best fit. [0] On Wed, Dec 11, 2013 at 9:15 PM, Andy Isaacson <adi@hexapodia.org> wrote:

Intel is looking to take advantage of the growth opportunity networking represents, Schooler said. The market Intel is targeting is about $16 billion (£9.7bn), and the chip maker currently has about 5 percent of it.

agreed.
my reading between the lines: it is not a special chip, it is a special collection of many of them (20+) handling tier-1 core traffic encryption, which is an excellent point to aggregate a vulnerability in keying ciphers. (ignore public key for now, since we can just focus directly on session/temporal keys!)

one last amusing note, Google has gone whole hog on SDN: http://www.networkcomputing.com/data-networking-management/inside-googles-so... how amusing would it be if they implemented inter-DC IPsec keyed with RDRAND directly on compromised cores in one of these Highland Forest like SDN deployments? i can already see the updated napkin sketch now, and imagine the streaming swears pouring forth from the googlies once uncovered...
