Two Passes of Tiger Are Not One-Way [chapter]

Florian Mendel
2009 Lecture Notes in Computer Science  
In this article, we show a preimage attack on Tiger with two passes (16 rounds) with a complexity of about 2 174 compression function evaluations.  ...  Even though the attacks are only slightly faster than brute force search, they present a step forward in the cryptanalysis of Tiger.  ...  Preimage Attack on Two Passes of Tiger Before describing the preimage attack on the compression function of Tiger reduced to 2 passes (16 rounds), we first have a closer look at the key schedule of Tiger  ...

On another occasion, I was making my way to a pass towards which the beaters were to drive a herd of spotted-deer, when two tigers crossed n 4 path, and walked into the ravine I was about to beat, without  ...  The tigers immediately turned, dashed through the line of beaters, fortu- nately without killing any, and made their way into a dense bamboo thicket from whence twenty elephants could not have driven them  ...

There are two kinds of death by lightning: one from fright, where no wounds are to be found, the other from being struck where wounds are to be found.

When the depredations of a tiger are complained of by the villagers, two or three small buffa- loes are tied up to near the place where the tiger is supposed to be, and the chances are, that one is killed  ...  This fact being ascertained, the shikaries (game keepers) reconnoitre, and having decided on the proper way to beat, build michans near the place, where the beast is likely to pass when driven ; the tiger  ...

The mahouts, thoroughly alive to the fact that tigers are not likely to present themselves, keep their beasts in rank so regular that no likely patch of cover shall be passed unbeaten ; and we are off.  ...  Three of our four guns are sent as ‘‘ stops” to advanced posts up the nullah, whitherward they make their way by forest routes ; one remains to drive along the nullah bed, he being flanked on either hand  ...

In beat- ing up a tiger in a nullah, guns are stationed in a U on either bank, while two guns come on with the beating elephants, flanking the line in case the tiger breaks back.  ...  ‘‘So with chatting and jolting and tails swinging and elephants lunching by the way, we reach the point where the howdah ele- phants are waiting; where the tigers and rhinos are waiting also, let us hope  ... 

Tiger: A fast new hash function [chapter]

Ross Anderson, Eli Biham
1996 Lecture Notes in Computer Science  
Among those cryptographic hash function which are not based on block ciphers, MD4 and Snefru seemed initially quite attractive for applications requiring fast software hashing.  ...  Furthermore, all these functions were designed for 32-bit processors, and cannot be implemented e ciently on the new generation of 64-bit processors such as the DEC Alpha.  ...  We also believe that they are one-way a n d m ultiplication-free And93] . The e ciency of this function is partially based on the potential parallelism in its design.  ...

On opening a door in the side of the tiger, a row of keys may be seen just withinside ; although awkwardly placed, and not very easily come at, they may be played upon in a clumsy way, and may be made  ...  Behind the keys are two rows of copper pipes, in unison with each other, two unisons being played by each key: either or both rows of pipes may be made silent by drawing out one or two stops placed by  ...

The flames ye from all parts of the cage, but it was not till the door-way was in a blaze that any motion of the tiger could be perceived.  ...  The tiger did not hurt any one, but in the scuffle, two natives got run through the foot, and a European soldier and a child were slightly wounded in the arm.  ...

Tigers are generally hunted in two ways: one is, shooting from the howdah of a “‘ pad” ele- phant, which is a comparatively safe method ; and the other is to shoot them from a meechaum, or platform of  ...  We were not looking especially for tigers, but were ready for anything that came; and we soon arrived at the village where we were to pass the night.  ...

This program allows students to perform meaningful hands-on calculations with quantum circuits and algorithms, without requiring knowledge of advanced mathematics.  ...  A combination of pen-and-paper exercises and IBM Q simulations helps students understand the structure of quantum gates and circuits, as well as the principles of superposition, entanglement, and measurement  ...  Next we define two two-qubit gates: the SWAP gate, which simply swaps the colors of the two input marbles, and the control-NOT (CNOT) gate that applies NOT on one marble conditional on the color of the  ...

The tiger or leopard that steps in bird lime does not step gracefully out of it and run away. He tries to bite the stuff from his feet and then he gets it on his face.  ...  First of all, one should examine and interpret carefully a few of his own dreams. This will bring to light cer- tain tendencies which are not obtaining full satisfaction in the waking life.  ...

Collisions and Near-Collisions for Reduced-Round Tiger [chapter]

John Kelsey, Stefan Lucks
2006 Lecture Notes in Computer Science  
This extends to a collision-finding attack on 17 rounds of the Tiger hash function in time of about 2 49 compression function invocations.  ...  We describe a collision-finding attack on 16 rounds of the Tiger hash function requiring the time for about 2 44 compression function invocations.  ...  As the full Tiger operates on 24 rounds, this attack gets through two thirds of Tiger, with work equivalent to 2 44 compression function invocations.  ...
