• Sommario/riassunto: Public key cryptography is a major interdisciplinary subject with many real-world applications, such as digital signatures. A strong background in the mathematics underlying public key cryptography is essential for a deep understanding of the subject, and this book provides exactly that for students and researchers in mathematics, computer science and electrical engineering. Carefully written to communicate the major ideas and techniques of public key cryptography to a wide readership, this text is enlivened throughout with historical remarks and insightful perspectives on the development of the subject. Numerous examples, proofs and exercises make it suitable as a textbook for an advanced course, as well as for self-study. For more experienced researchers it serves as a convenient reference for many important topics: the Pollard algorithms, Maurer reduction, isogenies, algebraic tori, hyperelliptic curves and many more.

• Sommario/riassunto: Brings together the key statements from the main debates in feminist film theory in Britain and the United States since 1970 Divided into six sections for ease of use: Taking up the Struggle; The Language of Theory; The Female Spectator; Textual Negotiations; Fantasy, Horror and the Body; Re-Thinking DifferencesAn introduction setting out the key debates in feminist film theoryIntroductions to each sectionThe book maps the impact of major theoretical developments - structuralist and semiotic theory; psychoanalysis; theories of ideology, language and discourse - on this growing field, in terms of both theoretical shifts and changes in methodologies. The relationship of feminist film theory to feminist media and cultural studies is outlined, as is the relationship between developments in feminist film theory and feminist film making. Includes readings from Laura Mulvey, Jacqueline Rose, Mary Ann Doane, Tania Modleski, Annette Kuhn, Jackie Stacey, Elizabeth Cowey, Linda Williams, bell hooks, Teresa de Lauretis. For the past twenty-five years, cinema has been a vital terrain on which feminist debates about culture, representation and identity have been fought. This anthology seeks to chart the history of those debates, bringing together the key statements in feminist film theory in Britain and the United States since 1970. The book maps the impact of major theoretical developments in this growing field - from structuralism and psychoanalysis to post-colonial theory, queer theory and postmodernism in the 1990s - interms of both theoretical shifts and changes in methodologies. Organised into six sections, the readings deal with a wide range of topics: oppressive images; woman" as fetishised object of desire; female spectatorship; film audiences; issues of fantasy and desire in popular film; and the cinematic pleasures of black women and lesbian women. The centrality of a feminist "politics of vision" unites all the readings in this book.Key Features"
