Book Description
The protection of sensitive information against unauthorized access or fraudulent changes has been of prime concern throughout the centuries. Modern communication techniques, using computers connected through networks, make all data even more vulnerable for these threats. Also, new issues have come up that were not relevant before, e. g. how to add a (digital) signature to an electronic document in such a way that the signer can not deny later on that the document was signed by him/her. Cryptology addresses the above issues. It is at the foundation of all information security. The techniques employed to this end have become increasingly mathematical of nature. This book serves as an introduction to modern cryptographic methods. After a brief survey of classical cryptosystems, it concentrates on three main areas. First of all, stream ciphers and block ciphers are discussed. These systems have extremely fast implementations, but sender and receiver have to share a secret key. Public key cryptosystems (the second main area) make it possible to protect data without a prearranged key. Their security is based on intractable mathematical problems, like the factorization of large numbers. The remaining chapters cover a variety of topics, such as zero-knowledge proofs, secret sharing schemes and authentication codes. Two appendices explain all mathematical prerequisites in great detail. One is on elementary number theory (Euclid's Algorithm, the Chinese Remainder Theorem, quadratic residues, inversion formulas, and continued fractions). The other appendix gives a thorough introduction to finite fields and their algebraic structure.

Book Description
Cuban independence arrived formally on May 20, 1902, with the raising of the Cuban flag in Havana - a properly orchestrated and orderly inauguration of the new republic. But something had gone awry. Republican reality fell far short of the separatist ideal. In an unusually powerful book that will appeal to the general reader as well as to the specialist, Louis A. Perez, Jr., recounts the story of the critical years when Cuba won its independence from Spain only to fall in the American orbit.The last quarter of the nineteenth century found Cuba enmeshed in a complicated colonial environment, tied to the declining Spanish empire yet economically dependent on the newly ascendant United States. Rebellion against Spain had involved two generations of Cubans in major but fruitless wars. By careful examination of the social and economic changes occurring in Cuba, and of the political content of the separatist movement, the author argues that the successful insurrection of 1895-98 was not simply the last of the New World rebellions against European colonialism. It was the first of a genre that would become increasingly familiar in the twentieth century: a guerrilla war of national liberation aspiring to the transformation of society.The third player in the drama was the United States. For almost a century, the United States had pursuedthe acquistion of Cuba. Stepping in when Spain was defeated, the Americans occupied Cuba ostensibly to prepare it for independence but instead deliberately created institutions that restored the social hierarchy and guaranteed political and economic dependence. It was not the last time the U.S. intervention would thwart the Cuban revolutionary impulse.

Book Description
Cuban-Americans are beginning to understand their long-standing roots and traditions in the United States that reach back over a century prior to 1959. This is the first book-length confirmation of those beginnings, and its places the Cuban hero and revolutionary thinker José Martí within the political and socioeconomic realities of the Cuban communities in the United States of that era. By clarifying Martí’s relationship with those communities, Gerald E. Poyo provides a detailed portrait of the exile centers and their role in the growth and consolidation of nineteenth-century Cuban nationalism. Poyo differentiates between the development of nationalist sentiment among liberal elites and popular groups and reveals how these distinct strains influenced the thought and conduct of Martí and the successful Cuban revolution of the 1890s.

Book Description
In Wizards and Scientists Stephan Palmié offers a corrective to the existing historiography on the Caribbean. Focusing on developments in Afro-Cuban religious culture, he demonstrates that traditional Caribbean cultural practices are part and parcel of the same history that produced modernity and that both represent complexly interrelated hybrid formations. Palmié argues that the standard narrative trajectory from tradition to modernity, and from passion to reason, is a violation of the synergistic processes through which historically specific, moral communities develop the cultural forms that integrate them. Highlighting the ways that Afro-Cuban discourses serve as a means of moral analysis of social action, Palmié suggests that the supposedly irrational premises of Afro-Cuban religious traditions not only rival Western rationality in analytical acumen but are integrally linked to rationality itself. Afro-Cuban religion is as “modern” as nuclear thermodynamics, he claims, just as the Caribbean might be regarded as one of the world’s first truly “modern” locales: based on the appropriation and destruction of human bodies for profit, its plantation export economy anticipated the industrial revolution in the metropolis by more than a century. Working to prove that modernity is not just an aspect of the West, Palmié focuses on those whose physical abuse and intellectual denigration were the price paid for modernity’s achievement. All cultures influenced by the transcontinental Atlantic economy share a legacy of slave commerce. Nevertheless, local forms of moral imagination have developed distinctive yet interrelated responses to this violent past and the contradiction-ridden postcolonial present that can be analyzed as forms of historical and social analysis in their own right.
