A low Hamming weight product (LHWP) exponent is used to increase the efficiency of cryptosystems based on the discrete logarithm problem (DLP). In this paper, we introduce a new tool, called a Parameterized Splitting System, to analyze the security of the DLP with LHWP exponents. We apply a parameterized splitting system to attack the GPS identification scheme modified by Coron, Lefranc and Pou...

We consider the discrete logarithm problem (DLP) in degree 0 class groups of non-hyperelliptic curves of genus 3 over finite fields Fq. Using a recent index calculus algorithm with double large prime variation by the author, heuristically, one can solve this problem in a time of Õ(q). In this work, we study this problem from a full cost perspective. We argue that heuristically, using a 3-dimens...

Modeling a complex phenomenon such as the mind presents tremendous computational complexity challenges. Modeling field theory (MFT) addresses these challenges in a non-traditional way. The main idea behind MFT is to match levels of uncertainty of the model (also, a problem or some theory) with levels of uncertainty of the evaluation criterion used to identify that model. When a model becomes mo...

The relationship and possible interplay between different knowledge representation and reasoning paradigms is a fundamental topic in artificial intelligence. For expressive knowledge representation for the Semantic Web, two different paradigms – namely Description Logics (DLs) and Logic Programming – are the two most successful approaches. A study of their exact relationships is thus paramount....

Digital light processing (DLP) is an accurate additive manufacturing (AM) technology suitable for producing micro-parts by photopolymerization. As most AM technologies, anisotropy of parts made by DLP is a key issue to deal with, taking into account that several operational factors modify this characteristic. Design for this technology and photopolymers becomes a challenge because the manufactu...

In this paper, we discuss solving the DLP over GF (36·97) by using the function field sieve (FFS) for breaking paring-based cryptosystems using the ηT pairing over GF (3 ). The extension degree 97 has been intensively used in benchmarking tests for the implementation of the ηT pairing, and the order (923-bit) of GF (3 6·97) is substantially larger than the previous world record (676-bit) of sol...

DLP (Digital Light Processing) is about to invade stereo applications, one of the last bastions of CRT projection technology. This paper presents various methods for achieving stereo and their application to DLP projectors. The newly developed sequential stereo capable projectors are also introduced and their performance characteris tics discussed along with artifacts. Also presented are ways t...

This paper presents a new simple scheme for theft-protected proprietary certificate problem by introducing a mobile phone as an additional requirement for the proprietor and this scheme is analyzed to be more secured than the one presented by M. Jakobsson, et al. Secondly we present the proprietary certification process using Elliptic Curve Discrete Log Problem (ECDLP) instead of Discrete Log P...

Drosophila melanogaster follicle stem cells are controlled by Wingless (Wg) ligands secreted 50 µm away, raising the question of how long-distance Wg spreading occurs. In this issue of JCB, Wang and Page-McCaw (2014. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201403084) demonstrate a potential mechanism by which the heparan sulfate proteoglycan Dally-like (Dlp) promotes Wg travel, whereas matr...

Since VACOR was first introduced to the market as a fast acting rodenticide in 1975, it has been sold successfully throughout the United States. The VACOR line is sold over-the-counter as a ready-to-use bait for rats and mice. The DLP-787 rodenticide line was introduced to the market for sale to professional users only. This line includes both bait and mouse tracking products. It has been well ...
