Large classes of weak keys have been found for the block cipher algorithm IDEA, previously known as IPES [2]. IDEA has a 128bit key and encrypts blocks of 64 bits. For a class of 2 keys IDEA exhibits a linear factor. For a certain class of 2 keys the cipher has a global characteristic with probability 1. For another class of 2 keys only two encryptions and solving a set of 16 nonlinear boolean ...
To achieve the dramatic improvements in capacity and spectral efficiency needed for fifth generation (5G) systems to accommodate the ever increasing number of users who require ubiquitous access to high volumes of wireless data, three symbiotic technological directions are independently emerging [1]: • Increasing frequency reuse through the creation of smaller cells, referred to as picoand femt...
This is a review of recent results on conformal (super)algebras. It may be viewed as an amplification of my Wigner medal acceptance speech (given in July 1996 in Goslar, Germany) reproduced in the introduction. 0 Introduction. It is a well kept secret that the theory of Kac-Moody algebras has been a disaster. True, it is a generalization of a very important object, the simple finite-dimensional...
In this paper, the nonlinear transient vibration of a cylindrical shallow panel under lateral white noise excitation is studied. The panel is in contact with a non aging viscoelastic medium. Since the external load is a time varying random wide band process, deterministic and conventional approaches cannot be used. Instead, the evolution of the probability density function of the response is in...
the author intend to by studying the historical causes of the appearance of the novation in the west and explanation of its legal nature from past to present of french law, proves on the one hand that the novation does not extracted from the french civil code and in the shiite jurisprudence with quite similar terms even before the enactment of iranian civil code, was considered by the shiite su...
In this paper, an improved multi-objective differential evolution algorithm(IDEA) is proposed for multi-objective optimization problems. In IDEA, the select operator combines the advantages of DE with the mechanisms of Pareto-based ranking and distance density, besides, a randomly migration strategy is proposed. IDEA is implemented on four classical multi-objective problems, the simulation resu...
This article presents a new conceptual view on the conscious will. This new concept approaches our will from the perspective of the requirements of our neural-muscular system and not from our anthropocentric perspective. This approach not only repositions the will at the core of behavior control, it also integrates the studies of Libet and Wegner, which seem to support the opposite. The will do...
In this paper we reflect on the meaning and evolution of the microworld idea. We point out a crucial distinction between user manipulation and modification at three distinct but mutually dependent levels — the interface, superstructural and platform levels. We exploit a case study of two 8-year-old girls playing and rebuilding a simple video game, to argue for the importance of ease of interpla...
In this paper, a simplified version of the International Data Encryption Algorithm (IDEA) is described. This simplified version, like simplified versions of DES [8] [12] and AES [6] [7] that have appeared in print, is intended to help students understand the algorithm by providing a version that permits examples to be worked by hand. IDEA is useful teaching tool to help students bridge the gap ...
