Probability on groups and an application to cryptography [PDF]

Computer Science Journal of Moldova, 2015
In her thesis, Mosina introduced the concept of {\it mean-set of random (graph-) group-variables} and generalized Strong Law of Large Numbers (SLLN) to (graphs) groups, which she used for cryptanalysis of authentication schemes.

Length-based attacks in polycyclic groups

Journal of Mathematical Cryptology, 2015
The Anshel–Anshel–Goldfeld (AAG) key-exchange protocol was implemented and studied with the braid groups as its underlying platform. The length-based attack, introduced by Hughes and Tannenbaum, has been used to cryptanalyze the AAG protocol in this ...

Fracture Resistance of Composite Fixed Partial Dentures Reinforced with Pre-impregnated and Non-impregnated Fibers

Journal of Dental Research, Dental Clinics, Dental Prospects, 2012
Background and aims. The mechanical properties of fiber-reinforced composite fixed partial dentures (FPDs) are affected by fiber impregnation. The aim of this in vitro study was to compare the fracture resistance of composite fixed partial dentures ...

BRAID GROUP CRYPTOGRAPHY

, 2009
In the last decade, a number of public key cryptosystems based on com- binatorial group theoretic problems in braid groups have been proposed. We survey these cryptosystems and some known attacks on them. This survey includes: Basic facts on braid groups and on the Garside normal form of its elements, some known algorithms for solving the word problem ...

Braid Groups are Linear

The Annals of Mathematics, 2002
In a previous work [11], the author considered a representation of the braid group ρ: B_n\to GL_m(\Bbb Z[q^{\pm 1},t^{\pm 1}]) (m=n(n-1)/2), and proved it to be faithful for n=4. Bigelow [3] then proved the same representation to be faithful for all n by a beautiful topological argument. The present paper gives a different proof of the faithfulness for

Fracture Strength and Bending of Fiber-Reinforced Composites and Metal Frameworks in Fixed Partial Dentures

Frontiers in Dentistry, 2008
Objective: This in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (FRC) and cast metal frameworks used for fabrication of inlay fixed partial dentures (IFPDs). Materials and Methods: Seventy-two

Some Aspects of Mathematical and Physical Approaches for Topological Quantum Computation [PDF]

Computer Science Journal of Moldova, 2011
A paradigm to build a quantum computer, based on topological invariants is highlighted. The identities in the ensemble of knots, links and braids originally discovered in relation to topological quantum field theory are shown: how they define Artin ...
