This paper presents the comparison and optimization of Galois field algorithm and IDEA(International data encrypted algorithm) using VHDL(xc2v40-6cs144)with the help of Xilinx-Ise (9.2) .In terms of security IDEA algorithm is very much superior where as in terms of timings Galois field is much better and is already patented of Ascom. These are cryptographic algorithm used for security purpose. ...

An algorithm for parallel multiplication of two n-bit ternary numbers is presented in this brief contribution. This algorithm uses the technique of column compression and computes the product in ( 2 [log, n1 + 2 ) units of addition time of a single-bit ternary full adder. This algorithm requires regular interconnection between any two types of cells and hence is very suitable for VLSI implement...

Power-associative antiflexible algebras have been studied by the author [3] and Kosier [2]. As a matter of terminology, we shall define an algebra as a finite dimensional vector space on which a multiplication is defined in which both distributive laws are satisfied. If A is an algebra over a field F of characteristic not two, then A has an attached algebra A + which is the same additive group ...

Let O be an order of discriminant D in an imaginary quadratic field K. In Lecture 19 we saw that there is a one-to-one relationship between isomorphism classes of elliptic curves with complex multiplication by O (the set EllO(C)), and equivalence classes of proper Oideals (the group cl(O)). The first main theorem of complex multiplication states that the elements of EllO(C) are algebraic intege...

For making elliptic curve point multiplication secure against side-channel attacks, various methods have been proposed using special point representations for specifically chosen elliptic curves. We show that the same goal can be achieved based on conventional elliptic curve arithmetic implementations. Our point multiplication method is much more general than the proposals requiring non-standar...

Initially, a design study is presented for a W-band planar coupled-cavity backward wave oscillator at 94.5 GHz. It is numerically simulated using CST particle-in-cell (PIC)-3D simulator and same design validated with another PIC-3D code. Further, output powers of several BWOs combines in a typical manner which resulted power multiplication order of 2.5 times and electronic efficiency multiplica...

Micropropagation of banana (Musa paradisiaca Linn.) var Grand naine was carried out with media sterilized by microwave radiation. Microwave oven was effectively used to sterilize the media for in vitro shoot-multiplication of banana against autoclave. Sterilization of media in microwave oven was successfully achieved at 900W/200 ml media (4 min). In vitro shoot-multiplication was higher in the ...

in this paper, we determine the structure of the space of multipliers of the range of a composition operator cφ that induces by the conditional expectation between two lp() spaces.

We present a new geometric interpretation of equivariant cohomology in which one replaces a smooth, complex G-variety X by its associated arc space J∞X, with its induced G-action. This not only allows us to obtain geometric classes in equivariant cohomology of arbitrarily high degree, but also provides more flexibility for equivariantly deforming classes and geometrically interpreting multiplic...

SAGE (Serial Analysis of Gene Expression) experiments generate short nucleotide sequences called 'tags' which are assumed to map unambiguously to their original transcripts (1 tag to 1 transcript mapping). Nevertheless, many tags are generated that do not map to any transcript or map to multiple transcripts. Current bioinformatics resources, such as SAGEmap and TAGmapper, have focused on reduci...
