In 1999, Kipnis and Shamir showed that a particular public key algorithm — known as the Hidden Field Equations scheme (HFE) — could be reduced to a system of overdefined quadratic equations ("overdefined" means that there are more equations than unknowns). Subsequently, other ciphers have been studied to see what of systems of equations can be produced (Biryukov and De Cannière, 2003), including Camellia, KHAZAD, MISTY-1 and KASUMI. http://www.worldhistory.com/wiki/X/XSL-attack.htm      Encyclopedia4U - Physics - Encyclopedia Article Chemistry draws on many fields of physics, particularly quantum mechanics, thermodynamics and electromagnetism. A more comprehensive list of physics topics is also available. In 1733, Bernoulli used statistical arguments with classical mechanics to derive thermodynamic results, initiating the field of statistical mechanics. http://www.encyclopedia4u.com/p/physics-1.html      5 Electron and SubQuantum Field Theory – SubQFT Field equations are amplified up to a full set of simultaneous equations by the law of motion of subcurrents in the field. Field equations resisted the conception of subcharges at rest responsible for the field of an electron at rest. The work postulates that the unitary subquantum field is a field described by Maxwell–Lorentz equations with regard to its potential, the right sides of which include continuously distributed charged subcurrents. http://www.ltn.lv/~elefzaze?l=en&c=05      Publications of the SPACES team Suitable as a text for a graduate or advanced undergraduate course in mathematics or computer science, this book offers an indispensable reference for students, researchers, and engineers interested in mathematical computation, computer algebra (software), and systems of algebraic equations. Given a geometric object defined by rational parametric equations, we show how to compute a disjunction of implicit equations and inequations that define exactly the same object by means of regular systems. It is done first in Maple by translating the geometric relations into polynomial equations, decomposing the obtained system of polynomials into irreducible representative triangular sets, and finding an adequate numerical solution from each triangular set. http://www-calfor.lip6.fr/~safey/Spaces/publications.html      hidden (errors,hidden,memory,programming,source) Java implementation of the public key cryptosystem hidden Field Equations (HFE). hidden under Misc in the menu, you'll find a big list of one-liners about computers and programming. Enumerates a selected file system directory as a collection of objects, file properties returned include size, creation date, last write date, last access date, archive, system, readonly and hidden flags. http://www.programming-x.com/programming/hidden.html      Topic: Relativistic wave equations Solutions of relativistic wave equations in superpositions of Aharonov–Bohm, magnetic, and electric fields. Construction of relativistic quantum fields in the framework of white noise analysis. The bundles of algebraic and Dirac–Hestenes spinor fields. http://topics.aip.org/0365P.html      finite (code,finite,fortran,java,prolog,scheduling,state) The " finite DIfference SOLver/Cartesian Arbitrary Domain SOLver" is a program package for the solution of partial differential equations. Fortran 90 routines, translated by John Burkhardt from the original Fortran 77, for the solution of a set of N nonlinear equations in N unknowns using Powell's method, and for the minimization of M nonlinear functions in N unknowns, using the Levenberg-Marquardt method. Java implementation of the public key cryptosystem Hidden Field Equations (HFE). http://www.programming-x.com/programming/finite.html      Hidden Field Equations public key cryptosystem home page (HFE) The complexity of relinearization depends on the number of unknowns and equations not on the size of inputs or outputs. HFE+ consists of adding some random equations to HFE, see [ IP2, DEA, IP7 ]. This very new, amazing, and powerful attack consists of 2 components A, B: We transform a small system of marginally defined quadratic equations into a huge system with much more equations that unknowns. http://www.minrank.org/hfe      Function field Algorithms for computing invariants of number fields and function fields. The main algorithm computes an integral basis of an algebraic function field using Puiseux expansions. The form and function of the crop circles are examined through field surveys, geometrical analysis, aerial photography, books and videos. http://omniknow.com/essays/Function_field.html      The revealed secrets of classical electrodynamics The question of the charged particle stability can only be solved classically by considering other non-electric forces, such as the magnetic field and scalar field forces. Equation (20) is a power flow balance between the power provided by an external source, the change in time of the total field energy, and the energy flow in the form of electro-magnetic radiation. Equation (21) is a force balance between the force applied by an external source, the field stress and the change in time of the momentum of the electro-magnetic radiation. http://home.wanadoo.nl/raccoon      Hidden Field Equations (HFE) - Variations and Attacks The second chapter also considers the speed of HFE, its security parameters, and which difficulties arise for non-surjective versions of HFE. The system is based on polynomials over finite fields and called "Hidden Field Equations" (HFE). Hidden Field Equations (HFE) - Variations and Attacks http://www.christopher-wolf.de/dpl      Fields and Particles Bookmarks Structure of Dirac Matrices and Invariants for Nonlinear Dirac Equations, Eprints The Calculated Photon: Visualization of a Quantum Field Regularization and Renormalization of Quantum Field Theories on Noncommutative Spaces, Eprints http://www.geocities.com/diahmed/bookmark2.html      Universal Force Field The equations and parameters are not secret, and the weaknesses of the force field are not hidden. See also: Planaria Software's ArgusLab ; and the molecular crystals package MolCryst. But who knows if it's any good; the equations, parameters and benchmarks for H-bonds in modified UFF have not been published. http://www.chm.colostate.edu/mmac/uff.html      Electron and SubQuantum Field Theory After that great moment of geometrization the symmetry was naturally observed (kept) – the symmetry of electromagnetism equations, written down in 4-vector's form, relatively to transformations from Lorenz group, the godfather of which was Henri Poincaré. It exists, hence it is a solution for the joint system of the ML-equations and the subquantum source motion equations. Qualitative analysis of subquantum level field scalar component manifestation in our corpuscular (quantified) world makes us to anticipate violation of symmetry of magnetic moment values in proton-antiproton (hadron-antihadron) pairs, masses at rest and other low-energy parameters. http://www.ltn.lv/~elefzaze?l=en&c=05      Hypercomplex Numbers - Maxwell Equations When a current appears in an electrical conductor due to a changing magnetic field, the direction of that current is always such that the field it produces will oppose that of the original changing magnetic field. We postulated the field equations for the quaternion formulation, but we will now prove here that the second circuital law is really just an algebraic identity, and so need not be postulated at all. Now, electric currents are produced by electric fields, so the appearance of a current in the conductor means that an electric field has to have been created by the changing of the magnetic field relative to the conductor. http://www.hypercomplex.com/research/emgrav/mxwleq.htm      Physical Space as a Quaternion Structure: Maxwell-Equations wrote the second edition of his Treatise on Electricity and Magnetism he included a quaternion representation of his electromagnetic equations, but he did not include both left-hand and right-hand derivatives, and so his work is fundamentally different from that presented here. And, the antisymmetric derivative of the electric field is the negative of the symmetric derivative of the magnetic field; the first representing a real physical law, while the second being easily proven an algebraic identity when given the definitions of the electric and magnetic fields above. Thus, with the inclusion of the missing temporal field the description of the action of a charged material particle is complete; we infer such a particle must have an extended structure with a variable intrinsic pulse in addition to its quantum mechanically determined fixed intrinsic spin. http://www.hypercomplex.com/research/emgrav/hypcx-p20001015.html      Who we are He has also been active in the field of bioinformatics and taxonomic computing. Within the SETI field, he is interested in the potential contributions of evolutionary biology to a better understanding of the origin and planetary distribution of intelligence, and the evolution of morphological diversity in geological time. Within the SETI field, he writes about the range of approaches that could be used to detect ETI. http://www.ieti.org/who.html      The Physics of Consciousness Engineering However, to calculate the actual value of the field one must know the initial or boundary, values of the field, which provide a baseline for all subsequent changes. The electric field, of course, can cause or induce change of sufficient magnitude to breach the quantum threshold and result in observable change. Even though the zero-point energy in any particular mode of an electromagnetic field is minute, there are so many possible modes of propagation (frequencies, directions) in open space, the zero-point energy summed up over all possible modes is quite enormous; in fact, greater than, for example, nuclear energy densities. http://www.geocities.com/iona_m/Chaosophy3/ConEgineer.html      Cryptology ePrint Archive We demonstrate both at the example of the Hidden Field Equations (HFE) system and outline how they can be adapted to similar systems. Although some of them have been successfully broken, the area is still vital and promises interesting algorithms with low computational costs, short message, and signature sizes. In addition, we compare the running time of the previously known technique ``polynomial interpolation" with our new developments both from a theoretical perspective and by empirical studies. http://eprint.iacr.org/2003/089      Cryptanalysis of the HFE Public Key Cryptosystem - Kipnis, Shamir (ResearchIndex) A natural generalization of this approach is to consider systems of several modular equations in several variables. 29 Two New Families of Asymmetric Algorithms (context) - Patarin, Equations et al. In this paper we consider Patarin's Hidden Field Equations (HFE) scheme, which is believed to be one of the strongest schemes of this type. http://citeseer.nj.nec.com/kipnis99cryptanalysis.html      Ritter's Crypto Glossary and Dictionary of Technical Cryptography These simple substitution ciphers with small, fixed tables (or even just equations for such tables) are also extremely vulnerable to attacks using ciphertext only. The affine equation thus represents one way to set up the table, as a particular simple permutation of the letters in the table. But that scary feeling is just an expected consequence of a field which has allowed various unsupported claims and unquestioned beliefs to wrongly persist (see old wives' tales). http://www.ciphersbyritter.com/GLOSSARY.HTM      Extended Maxwell's Equations: compact formulations in physics Central derivations from Maxwell's equations with respect to all important phenomena inside electrodynamics are shown as a new Mind Map with memorable Memo Maps using variations of famous "Maxwell's Hand" The idea for the following relativistic equation was an impuls - energy - quantum formulation on the basis of The difference between maxwell's equations in classic field theory and quantum field theory is shown in red boxes. http://www.innopro.de/maxwell_equations.htm      Security General Applied Computer Security Associates - The Applied Computer Security Associates (ACSA) is a non-profit association of computer security professionals who have a common goal of improving the understanding, theory, and practice of computer security.

Parts of the source code can certainly be used in other projects. However, the software comes with no warranty as it is free of charge. http://www.christopher-wolf.de/hfe      The Math Forum - Math Library - Logic/Foundations History; applications and related fields and subfields; textbooks, reference works, and tutorials; software and tables; other web sites with this focus. Pages with definitions, descriptions, and the basics of Abstract Algebra, Numbers, Vector Algebra and Analysis, Vector Field Analysis, Logic and Formal systems, and more. Created by Mary Laycock for mathematics teachers, with the goal of providing a real understanding of mathematics through hands-on (manipulative) activities. http://www.mathquest.com/library/topics/logic/      Ordered field If every element of an ordered field lies between two elements of its rational subfield, then the field is said to be rationals (as for any field of characteristic 0), and the order on this rational subfield is the same as the order of the rationals themselves. + 1 for any number of summands; this implies that the field F has http://omniknow.com/essays/Ordered_field.html      Forward and Backward with the Foundation Rather than merely fixing a problem in Seldon's equations, this discovery makes them useless for prediction! The first section also treats what surprisingly little sf is about: the process of academic discovery -- library searches, conferences, the legal status of universities, the frustrations of blocked research, of venturing outside one's field. They're basically one more group of hidden superhuman controllers in a universe which, like the Marvel Multiverse, has managed to accumulate an embarrassing surplus of them. http://www.zompist.com/asimov.htm      Maxwell Maxwell showed that a few relatively simple mathematical equations could express the behaviour of electric and magnetic fields and their interrelation. , now known as Maxwell's equations, first appeared in fully developed form in Electricity and Magnetism (1873). His paper On Faraday's lines of force was read to the Cambridge Philosophical Society in two parts, 1855 and 1856. http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Maxwell.html      Consistency of G-invariant Kaluza-Klein theory (1) A Kaluza-Klein scheme is called "consistent" if (a) it admits a compactifying ground state solution: (b) if every solution of the resulting m-dimensional field equations can also be interpreted as a solution of the original (m + s)-dimensional theory*** The present paper is a continuation and, in a sense, also a closure of a series of papers [1-5] in which we investigated the geometrical meaning of "dimensional reduction" - a procedure for obtaining an effective four-dimensional multifield theory from a multidimensional uni- (or "few") field theory. This simple Kaluza-Klein theory was investigated in detail in ref. [2], and it will be sufficient for our purposes to restrict our attention mainly to this model also in the present paper*. http://www.cassiopaea.com/quantum_future/consistency.htm      Hidden Field Equations - Wiktionary Wiktionary does not have an entry for this word yet.
