A Framework for Short Tweak Tweakable Block Cipher
Elastic-Tweak: A Framework for Short Tweak Tweakable Block Cipher Avik Chakraborti1, Nilanjan Datta2, Ashwin Jha2, Cuauhtemoc Mancillas Lopez3, Mridul Nandi2, Yu Sasaki1 1 NTT Secure Platform Laboratories, Japan 2 Indian Statistical Institute, Kolkata, India 3 Computer Science Department, CINVESTAV-IPN, Mexico [email protected], nilanjan isi [email protected], [email protected], [email protected], [email protected], [email protected] Abstract. Tweakable block cipher (TBC), a stronger notion than stan- dard block ciphers, has wide-scale applications in symmetric-key schemes. At a high level, it provides flexibility in design and (possibly) better security bounds. In multi-keyed applications, a TBC with short tweak values can be used to replace multiple keys. However, the existing TBC construction frameworks, including TWEAKEY and XEX, are designed for general purpose tweak sizes. Specifically, they are not optimized for short tweaks, which might render them inefficient for certain resource constrained applications. So a dedicated paradigm to construct short- tweak TBCs (tBC) is highly desirable. In this paper, we present a ded- icated framework, called the Elastic-Tweak framework (ET in short), to convert any reasonably secure SPN block cipher into a secure tBC. We apply the ET framework on GIFT and AES to construct efficient tBCs, named TweGIFT and TweAES. We present hardware and software results to show that the performance overheads for these tBCs are minimal. We perform comprehensive security analysis and observe that TweGIFT and TweAES provide sufficient security without any increase in the number of block cipher rounds when compared to GIFT and AES. -

IG CHANNEL FLECTRnN MULTIPLIER PLATES Bo Sundqvist Tanden Accelerator Laboratory, Uppsala, Sweden •Hr '.vACT: . *-. literature on zerotime detectors which use the emission of ". ocndary electrons from a thin foil is reviewed. The construction • a zerotiine detector using multiplication of the secondary •,'2Ctrons with two Mallard channel electron multiplier-plates (CEMP) •.' tandem is described. Results of tests of such a detector with a particles from a natural a source are given. Tstal time resolutions of about 200 ps (FVHM) with a Si(Sb) detector as the stop detector has been achieved. The contribution from the zerotiine detector is estimated to be less than 150 ps (FVJW). The application of this detector technique to the construction of a heavy-ion spectrometer o and a Be detector is discussed.

Adobe Photoshop® TIFF Technical Note 3 April 8, 2005
Adobe Photoshop® TIFF Technical Note 3 April 8, 2005 Adobe Photoshop® TIFF Technical Note 3 April 8, 2005 This document describes additions to the TIFF specification to improve support for floating point values. Readers are advised to cross reference terms and discussions found in this document with the TIFF 6.0 specification (TIFF6.pdf), the TIFF Technical Note for Adobe PageMaker® 6.0 (TIFF-PM6.pdf), and the File Formats Specification for Adobe Photoshop® (Photoshop File Formats.pdf). Page 1 of 5 Adobe Photoshop® TIFF Technical Note 3 April 8, 2005 16 and 24 bit Floating Point Values Introduction This section describes the format of floating point data with BitsPerSample of 16 and 24. Field: SampleFormat Tag: 339 (153.H) Type: SHORT Count: N = SamplesPerPixel Value: 3 = IEEE Floating point data Field: BitsPerSample Tag: 258 (102.H) Type: SHORT Count: N = SamplesPerPixel Value: 16 or 24 16 and 24 bit floating point values may be used to minimize file size versus traditional 32 bit or 64 bit floating point values. The loss of range and precision may be acceptable for many imaging applications. The 16 bit floating point format is designed to match the HALF data type used by OpenEXR and video graphics card vendors. Implementation 16 bit floating point values 16 bit floating point numbers have 1 sign bit, 5 exponent bits (biased by 16), and 10 mantissa bits. The interpretation of the sign, exponent and mantissa is analogous to IEEE-754 floating-point numbers. The 16 bit floating point format supports normalized and denormalized numbers, infinities and NANs (Not A Number). -

I needed a program to convert image files in the OpenEXR format to files in the Portable Pixmap format. So I wrote a program called exrtoppm. It resembles some of the other conversion programs which are part of the Netpbm suite of Portable (Bit, Gray, Pix)map programs. It is a command line program. I use it on Microsloth Winders; it should also work on unix-like systems, though I haven’t compiled it there, much less used it. This document includes the user documentation for the program, links to download the executalbe &/or the source code, installation instructions, & build instructions. 1 2 License One of the source code files, getopt.c, is in the public domain.
