AES

AES-NI in Laymen's Terms

What is AES-NI - first answer
AES-NI are a set of six new instructions introduced by Intel when we introduced the new 2010 Intel® Core™ processor family code named Westmere. AES-NI stands for Advanced Encryption Standard - New Instructions. These instructions implement hardware accelerated versions of certain compute intensive steps used in the AES (RijnDael) algorithm.

Okay - so what is the Advanced Encryption Standard (AES)?

AES Counter Mode details (Intel AES-NI implementation)


In this article we’ll take a closer look at AES counter (CTR) mode implementation from Intel® AES-NI library (it can be downloaded from http://software.intel.com/en-us/articles/download-the-intel-aesni-sample-library/).

AES stands for Advanced Encryption Standard and it is a symmetric encryption standard. More detailed information about AES at http://de.wikipedia.org/wiki/Advanced_Encryption_Standard.

Got AES Performance?

Is your AES implementation a bit sluggish?  Do you want to improve your cycle/byte and key generation efficiency?   If so, then you definitely want to check out the Intel® AES-NI Sample Library.  The “sample library” is more than just a library; it provides full source code along with a couple of examples.  The library consists mostly of hand-optimized assembly code routines that utilize Intel’s AES New Instruction

Have you Visited the Manageability Community Lately - Lots of New Content for You

 

Have you visited us lately? Lots of new content showing up recently on the ISN Manageability Community.

First of all, if you downloaded the Intel® AMT 6.0 SDK prior to May 24 (and it was first available about March 5, 2010), you will want to download the new version that eliminates a bug in the initial version:  New version (hotfix) -
Intel® AMT 6.0 SDK.

Next up, seven new blogs!!

Want a faster calculated hash and a block cipher? “Stitch” them!

Hello.

We just released the very interesting paper showing the way to speed up a pair of independent functions or algorithms, like a block cipher and a hash often called sequentially on the same input buffer.

One can greatly improve the utilization of the underlying microarchitecture’s execution resources by combining two algorithms and computing them together at the same time, we call it “stitching”.

Fast SHA-1

Hello.

If the speed of widely used cryptography algorithms (like AES or SHA-1) is of some interest to you, dear reader, then I’m welcoming you to this blog.

In a past few months I happened to be a part of breathtaking effort to improve performance of some widely used crypto algorithms. Today we are publishing our results on improving speed of Secure Hash Algorithm (SHA-1). /en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1

Updates today for our compilers, libraries and cluster toolkits

Today we released updates for our C++ and Fortran compilers, our Intel Math Kernel (MKL) and Intel Integrated Performance Primitives (IPP) libraries and Cluster toolkits. Noteworthy additions include outstanding performance enhancements, support of Intel® Advanced Vector Extensions (AVX) and inclusion of some elements that debuted in Intel® Parallel Studio last month.
