'''Fugue''' is a [[cryptographic hash function]] submitted by [[IBM]] to the [[NIST hash function competition]]. It was designed by Shai Halevi, William E. Hall, and Charanjit S. Jutla. Fugue takes an arbitrary-length message and compresses it down to a fixed bit-length (either 224, 256, 384 or 512 bits). The hash functions for the different output lengths are called Fugue-224, Fugue-256, Fugue-384 and Fugue-512. The authors also describe a parametrized version of Fugue. A weak version of Fugue-256 is also described using this parameterized version.


The selling point of Fugue is the authors' claimed proof that a wide range of current attack strategies based on [[differential cryptanalysis]] cannot be efficient against Fugue.  It is also claimed to be competitive with the NIST hash function [[SHA hash functions|SHA-256]] in both software and hardware efficiency, achieving up to 36.2 [[cycles per byte]] on an Intel Family 6 Model 15 Xeon 5150, and up to 25 [[cycles per byte]] on an Intel Core 2 processor T7700. On 45 nm Core2 processors, e.g. T9400, Fugue-256 runs at 16 cycles per byte using SSE4.1 instructions. On the newer Westmere architectures (32 nm), e.g. Core i5, Fugue-256 runs at 14 cycles/byte.


Fugue's design starts from the hash function [[Grindahl]], and like Grindahl uses the [[S-box]] from [[Advanced Encryption Standard|AES]], but it replaces the 4×4 column mixing matrix with a 16×16 "super-mix" operation which greatly improves diffusion. The "super-mix" operation is, however, only slightly more computationally expensive to implement than the AES mixing strategy.

== SuperMix ==
 
The 224 and 256 bit variants of Fugue work with a state which can be represented in 4 by 30 matrix of unsigned bytes, whereas the 384 and 512 bit variants work with a 4 by 36 byte matrix. Operations can be performed in-place on this state.
 
The core of the algorithm, known as the "SuperMix transformation", takes 4×4 matrix as input and returns a new 4x4 matrix. The input to SuperMix is simply the first four columns of the current 30-column state and the output is used to replace this same state area (i.e. SuperMix affects only the 4x4 matrix at the head of the state).
 
The SuperMix function can be defined as:
 
<math>
\text{SuperMix}(U) = \text{ROL} \left( M \cdot U +
\begin{pmatrix}
\sum_{j \ne 0} U_j^i & 0 & 0 & 0\\
0 & \sum_{j \ne 1} U_j^i & 0 & 0\\
0 & 0 & \sum_{j \ne 2} U_j^i & 0\\
0 & 0 & 0 & \sum_{j \ne 3} U_j^i
\end{pmatrix}  \cdot M^T \right)
</math>
 
where:
 
:<math>
M = \begin{pmatrix}
1 & 4 & 7 & 1\\
1 & 1 & 4 & 7\\
7 & 1 & 1 & 4\\
4 & 7 & 1 & 1
\end{pmatrix}
</math>;
:<math>U</math> is a 4x4 matrix of bytes (i.e. the matrix after the S-Box substitution of the input); and
:<math>M^T</math> is the transpose of M.
 
The transformation <math>ROL</math> takes a 4x4 matrix, and rotates the <math>i</math>-th row to the left by <math>i</math> bytes, i.e.
 
:<math>
\text{ROL}(W)_j^i = W_{j-i \pmod 4}^{i}
</math>
 
== Fugue 2.0 ==
Fugue 2.0 is a tweak of original Fugue, which runs at about twice the speed of Fugue for 256-bit output. The designers claim advanced proofs of resistance to differential collision attacks for this improved version.

I'm not discussing cheap knock offs or something that sounds similar. No, they want the real McCoy, the original, the official item. Well if you take a peek around the internet you will discover that you can get low-cost Pillow Animals. So armed with that expertise the concern ends up being, where is the best location to get them? Where is the one place that you can go and get a bargain and not get swindled? Well, in my opinion that location is. I believe it's the best place to purchase them.

Pillow professionals warn that when selecting the ideal bed pillow, consumers need to be on the look out for pillows that contain fibers that can cause allergies. Bed pillows which contain feathers or wool for example, may trigger allergic reactions in some people who are currently sensitive to these fibers. For this factor, it is essential to read the label that describes the kinds of fibers that a pillow consists of before you purchase it. Begin with a pillow that looks 'best' for you. Rest the means you normally do and slip the pillow under your neck. Do not hurry yourself to decide. Take a moment to 'settle down'. Turn around and try your favorite sleeping postures. Rate the pillow for comfort level. Orthopedic Pillows for the Traveling Individual

Due to the fact that it is made from anti-pill polar fleece, your all in one PJs will certainly maintain their fresh appearance for a long period of time. The Forever Lazy can be found in four stylish colors consisting of Workday Blues, Handkerchief Pinky Fuchsia, Black to Rest, and Asleep on the Job Gray. Many individuals like to get all 4 so they have a well-rounded pajama wardrobe. There ares a drawstring hood on these one piece fleece pajamas for those additional cold days. Although the feet are open, every order consists of a pair of footies to keep those toes toasty. As if that isn't really enough, there is even a matching neck pillow for staying comfortable and Forever Lazy on the sofa or taking a trip in the vehicle or on a plane.

When an individual's immune system becomes hypersensitive and reacts adversely to typically harmless substances, an allergic response takes place. Allergies can vary from moderate to severe and sometimes deadly reactions. Individuals are typically adverse certain sorts of medicines, animals and foods. Other allergies are caused by plants like yard, trees and weeds. Allergy signs likewise differ depending upon the type of allergy. While some may experience sneezing and a dripping nose, others might experience itchiness, hives and rashes.

Pillows and the bed room in basic is typically a rich habitat for dust mites. These dust mites live off fungi found in pillows. After the dust mites eat, they leave allergen feces. The fungi also soak up the allergen feces. Human beings likewise supply skin flakes, bodily fluids and germs that dust mites and fungi feed off. They also add 20 gallons of sweat into their bed when people sleep. This contributes to the zoo result, permitting much more bacteria to breed.

It is a relatively usual grievance that the back, neck and arms of a nursing mom are most strained while nursing a child, but with a proper breastfeeding pillow such problems may be a distant memory. Many of these pillows are ergonomically developed to ensure that they shield the nursing mommy from the most common complaint, back pain. The quality of these pillows improves with time. It improves with time and assists you have a nice noise sleep. Last long and with time it keeps on getting better with time. Memory foam pillow have an excellent quality. It would be a wonderful financial investment for your wellness and you would never ever be sorry for after you have actually gotten it, specifically when you have aching neck it would not leave you disappointed. Air Travel Measures

If you are a very tall individual, your pillow height should be higher. Most people fall under the typical range. Makers in some cases put a size chart on their boxes. Tall and average size individuals normally do effectively with memory foam pillows. Attempt them to get the very best fit. There are also some other materials that work well for supporting the neck and are likewise encouraging. In reality, they might work better for some people than memory foam. These other materials are buckwheat hulls, a natural option to memory foam, latex, which has very similar advantages as memory air, synthetic and foam down. Line up your materials with the best sides together (exactly what you want to reveal on the outside of the pillow) and lining up the cut edge. Lie down in your sleep position

The main reason experts warn versus positioning pillows in a baby's baby crib is the threat of suffocation. If an infant gets her face pressed into a pillow, she won't have the neck strength to move her head and draw her mouth and nose away. A pillow in an open case presents a risk also, considering that a baby could possibly get her head stuck inside the case. Children are likewise sensitive to allergens like dust mites, down and feathers, and resting on these products all night can cause serious allergic reactions. When to Present Pillows

Picking the best bed pillow likewise has much to do with your resting design. People who rest primarily on their side or back must look for a pillow that can normally support their head, shoulders and spinal column in the right position. The ideal bed pillow must not tilt your body in unnatural positions, as this will certainly cause neck and back pain. People who sleep on their tummy must choose a more flat pillow to reduce strain on the neck and back.
