Changing the scalar multiplication on a vector lattice

Lattice Attacks Against Elliptic-Curve Signatures with Blinded Scalar Multiplication

Elliptic curve cryptography is today the prevailing approach to get efficient public-key cryptosystems and digital signatures. Most of elliptic curve signature schemes use a nonce in the computation of each signature and the knowledge of this nonce is sufficient to fully recover the secret key of the scheme. Even a few bits of the nonce over several signatures allow a complete break of the sche...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Scalar mesons on the Lattice

The simulations of the light scalar mesons on the lattice are presented at the introductory level. The methods for determining the scalar meson masses are described. The problems related to some of these methods are presented and their solutions discussed.

Scalar Multiplication on Pairing Friendly Elliptic Curves

Efficient computation of elliptic curve scalar multiplication has been a significant problem since Koblitz [13] and Miller [14] independently proposed elliptic curve cryptography, and several efficient methods of scalar multiplication have been proposed (e.g., [8], [9], [12]). A standard approach for computing scalar multiplication is to use the Frobenius endomorphism. If we compute the s-multi...
