Partindo da clássica obra Massa e Poder (1960), de Elias Canetti, o estudo prossegue com o exame de dois ensaios de Peter Sloterdijk, Regras para o Parque Humano (1999) e O Desprezo das Massas (2000), e procura esclarecer as transformações do conceito de massa entre esses dois autores, da massa negra e molar de Canetti à massa colorida e gasosa de Sloterdijk. Sem a pretensão de percorrer o conceito na história da filosofia política, pretende-se fazer notar como a reflexão sobre a natureza, as potencialidades e os riscos das multidões assume um papel cada vez mais importante no pensamento sobre a política e cultura contemporâneas. As catastróficas experiências das grandes guerras mundiais mostraram a urgência de uma análise séria dos comportamentos direcionados ou espontâneos de massa, principalmente para aqueles que desejam pensar sobre o que ainda podem significar, hoje, idéias como democracia ou humanidade. Se, como nota Sloterdijk, o humanismo não é mais capaz de domesticar o homem contemporâneo, bombardeado cada vez mais intensamente por mídias embrutecedoras, outras antropotécnicas - mais efetivas que o velho humanismo na sua forma de domesticar o homem - deverão substituí-lo em nome de um determinado projeto de humanidade. Massa e humanização apresentam-se hoje como tópicos estreitamente relacionados, e refletir sobre o que significa ser humano hoje e o que poderá significar amanhã exige uma maior compreensão dos fenômenos de massa no século que se inicia. / Abstract: This work proposes to examine the phenomenon of human masses and their cultural, social and political implications for the XXIth century. Taking as its point of depart Elias Canetti's classic essay Mass und Macht (1960), the study continues with an examination of two texts by Peter Sloterdijk, Regeln für den Menschenpark (1999) and Die Verachtung der Massen (2000), and seeks to clarify the transformations of the concept of mass between these two authors, from Canetti's black and molar mass to the gaseous and colorful mass of Sloterdijk. Without the pretension of examining the concept of mass through the whole history of political philosophy, its aim is to make clear how the reflection on the nature, the potential and risks of the masses has an increasingly important role in thinking about contemporary politics and culture. The disastrous experiences of the great world wars has shown the urgency of a serious analysis of the directed or spontaneous conduct of the masses, especially for those who want to think about what the ideas of democracy or humanity can still mean today. If, as Sloterdijk remarked, humanism is no longer capable of domesticating contemporary man, as he is increasingly bombed by brutal media, other antropotechniques - more effective than the old humanism to attain human domesticating - should replace it in the name of a particular project of humanity. Mass and humanization present themselves today as closely related topics, and to reflect about what it means to be human today and what could that mean tomorrow requires greater understanding of the phenomena of mass in the century that begins. / Mestrado / Mestre em Filosofia

This way, the psychic exile , comdemns the person to a radical intimate weirdness feeling, where the world and the oneself unintelligibility prevails. From the psychoanalytic standpoint, this entity is called psychosis; from the current use of the language standpoint, it is called madness. Through a transversal cut in Elias Canetti biography, from the time the writer lived in and his relations to the German language, culture and literature, it is possible to identify in Peter Kien character and in the novel Auto de F?, the points that support our hypothesis related to the self exile : that the use of the language that Canetti does, enables him to make a perfect representation of the psychic laceration that hits the novel protagonist, according to his relations to the world and to the other characters, as well as the subjective question fulfills the metaphor role of a world under fragmentation, not only from the one that was used as raw material for the work, also from the world today, that is nothing but the logical and direct consequence that was already announced at the beginning of the XX century. / O sentido de ex?lio de si que foi privilegiado neste trabalho se constitui em um tipo de ex?lio que n?o ? escolhido e tampouco ? imposto de fora, pois a sua ocorr?ncia se relaciona com uma injun??o estrutural, da ordem do psiquismo. Sendo assim, o ex?lio ps?quico condena o sujeito a um sentimento de radical estranheza ?ntima onde o que prevalece ? a ininteligibilidade do mundo e de si mesmo. Do ponto de vista da teoria psicanal?tica, esta entidade ? denominada de psicose; do ponto de vista do uso corrente da l?ngua, ? chamada de loucura. Atrav?s de um corte transversal que vai da biografia de Elias Canetti, da ?poca em que o escritor viveu e de suas rela??es com a l?ngua alem? e com a literatura, procuramos identificar no personagem Peter Kien e no romance Auto de F?, os pontos que apoiam a nossa hip?tese em rela??o ao ex?lio de si : que o uso que Canetti faz da linguagem propiciou-lhe fazer uma perfeita representa??o do esfacelamento ps?quico que assola o protagonista do romance em suas rela??es com o mundo e com os outros personagens, assim como esta quest?o subjetiva cumpre o papel de met?fora de um mundo em fragmenta??o, n?o s? daquele que lhe serviu de mat?ria-prima para a confec??o da obra, como do mundo de hoje, que nada mais ? do que a consequ?ncia l?gica e direta do que j? se anunciava no alvorecer do s?culo XX.

The goal of the Master Thesis is to analyse the performance Eraritjaritjaka created by the leading director of German experimental theatre Heiner Goebbels. The first part exposes the new theatrical genre Théâtre musical as a theoretical framework. The following text focuses on Goebbels's theoretical views and the basics characetrs of his theatre poetics. The main part of this study is devoted to analysis of performance Eraritjaritjaka. The analysis itself focuses on the functioning of basic components of the performance, its principles and shifts in overall structure.

Elliptic curves were first proposed as a basis for public key cryptography in the mid 1980's. They provide public key cryptosystems based on the difficulty of the elliptic curve discrete logarithm problem (ECDLP) , which is so called because of its similarity to the discrete logarithm problem (DLP) over the integers modulo a large prime. One benefit of elliptic curve cryptosystems (ECCs) is that they can use a much shorter key length than other public key cryptosystems to provide an equivalent level of security. For example, 160 bit ECCs are believed to provide about the same level of security as 1024 bit RSA. Also, the level of security provided by an ECC increases faster with key size than for integer based discrete logarithm (dl) or RSA cryptosystems. ECCs can also provide a faster implementation than RSA or dl systems, and use less bandwidth and power. These issues can be crucial in lightweight applications such as smart cards. In the last few years, ECCs have been included or proposed for inclusion in internationally recognized standards. Thus elliptic curve cryptography is set to become an integral part of lightweight applications in the immediate future. This thesis presents an analysis of several important issues for ECCs on lightweight devices. It begins with an introduction to elliptic curves and the algorithms required to implement an ECC. It then gives an analysis of the speed, code size and memory usage of various possible implementation options. Enough details are presented to enable an implementer to choose for implementation those algorithms which give the greatest speed whilst conforming to the code size and ram restrictions of a particular lightweight device. Recommendations are made for new functions to be included on coprocessors for lightweight devices to support ECC implementations Another issue of concern for implementers is the side-channel attacks that have recently been proposed. They obtain information about the cryptosystem by measuring side-channel information such as power consumption and processing time and the information is then used to break implementations that have not incorporated appropriate defences. A new method of defence to protect an implementation from the simple power analysis (spa) method of attack is presented in this thesis. It requires 44% fewer additions and 11% more doublings than the commonly recommended defence of performing a point addition in every loop of the binary scalar multiplication algorithm. The algorithm forms a contribution to the current range of possible spa defences which has a good speed but low memory usage. Another topic of paramount importance to ECCs for lightweight applications is whether the security of fixed curves is equivalent to that of random curves. Because of the inability of lightweight devices to generate secure random curves, fixed curves are used in such devices. These curves provide the additional advantage of requiring less bandwidth, code size and processing time. However, it is intuitively obvious that a large precomputation to aid in the breaking of the elliptic curve discrete logarithm problem (ECDLP) can be made for a fixed curve which would be unavailable for a random curve. Therefore, it would appear that fixed curves are less secure than random curves, but quantifying the loss of security is much more difficult. The thesis performs an examination of fixed curve security taking this observation into account, and includes a definition of equivalent security and an analysis of a variation of Pollard's rho method where computations from solutions of previous ECDLPs can be used to solve subsequent ECDLPs on the same curve. A lower bound on the expected time to solve such ECDLPs using this method is presented, as well as an approximation of the expected time remaining to solve an ECDLP when a given size of precomputation is available. It is concluded that adding a total of 11 bits to the size of a fixed curve provides an equivalent level of security compared to random curves. The final part of the thesis deals with proofs of security of key exchange protocols in the Canetti-Krawczyk proof model. This model has been used since it offers the advantage of a modular proof with reusable components. Firstly a password-based authentication mechanism and its security proof are discussed, followed by an analysis of the use of the authentication mechanism in key exchange protocols. The Canetti-Krawczyk model is then used to examine secure tripartite (three party) key exchange protocols. Tripartite key exchange protocols are particularly suited to ECCs because of the availability of bilinear mappings on elliptic curves, which allow more efficient tripartite key exchange protocols.
