AES-NI Performance Analyzed; Limited To 32nm Core i5 CPUs

2:00 AM – 02/02/2010 by Patrick Schmid and Achim Roos

Security is an important topic these days. However, it’s typically only recognized as important by professionals. If security were to suddenly turn into a mainstream selling point, though, then perhaps it’d make more sense for companies like Intel to promote it.

The Advanced Encryption Standard (AES) has already been adopted by the United States government—including the NSA—along with many other institutions. Intel’s 32nm Clarkdale-based CPUs (only the Core i5-600-series, so far) now promise significant performance benefits for AES encryption and decryption via new instructions. Today we’re looking at the real-world benefits of Intel’s AES-NI functionality, comparing a dual-core Core i5-661 with AES New Instructions (AES-NI) to a quad-core Core i7-870, which lacks the new encryption acceleration capability.

Encryption is used much more intensively than you might suspect. Consider Internet sites that hold you sensitive personal information, or utilize sensitive data for transactions. They all use protocols like Transport Layer Security (TLS) or Secure Sockets Layer (SSL). VoIP, instant messaging, and email may also be protected with these protocols. Virtual Private Networks (VPNs) and electronic payments are other popular encryption applications.

However, TLS and SSL are cryptographic protocols for secure communication, while AES is a general-purpose encryption standard. It can be used to encrypt individual files, data containers, archive files, entire drives (including thumb drives), and even multi-drive volumes. AES can be implemented in software, and there are products based on hardware acceleration as well, since encryption/decryption represent a rather significant workload. Solutions like TrueCrypt or Microsoft’s BitLocker, which is part of Windows Vista and Windows 7 Ultimate, are capable of encrypting entire partitions on the fly.

Google poised to become your phone company

Google poised to become your phone company

Could Google become a serious rival to AT&T and Verizon?

Could Google become a serious rival to AT&T and Verizon?

STORY HIGHLIGHTS

  • Google is set to become your new phone company, perhaps reducing your phone bill to zilch in the process.
  • Google has bought Gizmo5, an online phone company that is akin to Skype
  • Users could make and receive calls that bypass the per-minute billing on smartphones
  • Consultant: “If AT&T is Coca-Cola, Google is now 7-UP”

(Wired) — Google is set to become your new phone company, perhaps reducing your phone bill to zilch in the process.

Seriously.

Google has bought Gizmo5, an online phone company that is akin to Skype  but based on open protocols and with a lot fewer users. TechCrunch, which broke the news on Monday, reported that Google spent $30 million on the company.

Google announced the Gizmo acquisition on Thursday afternoon Pacific Time. Gizmo5′s founder Michael Robertson, a brash serial entrepreneur, will become an Adviser to Google Voice.

It’s a potent recipe — take Gizmo5′s open standards-based online calling system. Add to it the new ability to route calls on Google’s massive network of cheap fiber. Toss in Google Voice’s free phone number, which will ring your mobile phone, your home phone and your Gizmo5 client on your laptop.

Meanwhile you can use Gizmo5 to make ultracheap outgoing calls to domestic and international phone numbers, and free calls to Skype, Google Talk, Yahoo and AIM users. You could make and receive calls that bypass the per-minute billing on your smartphone.

Then layer on deluxe phone services like free SMS, voicemail transcription, customized call routing, free conference calls and voicemails sent as recordings to your e-mail account, and you have a phone service that competes with Skype, landlines and the Internet telephone offerings from Vonage and cable companies.

That’s not just pie in-the-sky dreaming.

Ask longtime VOIP watcher and consultant Andy Abramson, who introduced the idea of integrating Gizmo5 and Grand Central (now Google Voice), long before Google bought either.

“Google is now the the uncommon carrier,” Abramson said, punning on the iconic 7-UP commercials and the phrase “common carrier.” That refers to phone companies that operate on the traditional publicly switched network — a status that gives them benefits and obligations.

“If AT&T is Coca-Cola, Google is now 7-UP,” Abramson added.

“All of a sudden you have something that offers more than Skype,” Abramson said, saying the combo could now put Google in competition with phone and cable companies, IP “telephony” (VOIP) companies and Vonage. “But now you can do everything with Google and pay nothing and have a platform where engineers can build new things.”

Google acquires Gizmo5.com

Thursday, November 12, 2009 | 2:30 PM

Today we’re pleased to announce we’ve acquired Gizmo5, a company that provides Internet-based calling software for mobile phones and computers. While we don’t have any specific features to announce right now, Gizmo5′s engineers will be joining the Google Voice team to continue improving the Google Voice and Gizmo5 experience. Current Gizmo5 users will still be able to use the service, though we will be suspending new signups for the time being, and existing users will no longer be able to sign up for a call-in number.

We’ve acquired a number of small companies over the past five years, and the people and technology that have come to Google from other places have contributed in many ways, large and small, to all kinds of Google products. Since the GrandCentral team joined Google in 2007, they’ve done incredible things with Google’s technology and resources to launch and improve Google Voice.

We welcome the Gizmo5 team to Google and look forward to working together to bringing more useful features to Google Voice.

crypto that is not snake oil

Posted by John on 14th August 2009

I’ll reiterate to folks, I’m software agnostic.  Open source and on Linux?  Grand.  Often closed source, straight from that-supposed-devil company Microsoft?  Nifty.  OSX and whatever you want to run there?  Sure enough.

I’m just looking to get the job done well.  There really are times when one choice is better in my work, and times for the others also.  Each of us may have reasons to choose a ‘preferred’ system, or package type.  This is fine – live and let live, and all that. (your day will go better if you start to adopt that; I’m sure trying!)

I’d like to briefly hit a fave topic – cryptography. I suppose it all started with reading books too early, but that’s another story and I won’t bore you with my vice.  Suffice it to say, I was interested in simple transposition ciphers by the age of six or so, pencil and paper style.

Now we have other options.  Which is good, as my writing is terrible.  PGP commercial style.  GPG open source style.  Phil Zimmermann, with two N’s please! (kudos to Phil for making the world a better place)

Hushmail for secure email.  Full disk encryption by TrueCrypt, among others.  Much more secure VoIP that most other implementations.

Be careful of snake oil; noted security folks tend to frown on this and generally have a “doghouse” category for things that just aren’t right.  If something relies on security through obscurity, it automatically fails in my estimate.
