Usted, sin darse siquiera cuenta, est\u00e1 utilizando criptograf\u00eda a diario: al conectar el m\u00f3vil, al sacar dinero del cajero, al navegar por Internet, al enviar mensajes por tel\u00e9fono, al pagar con el abono de transporte. Incluso su documento de identidad y su pasaporte incluyen elementos criptogr\u00e1ficos. Pero \u00bfsabe c\u00f3mo funcionan? Y sobre todo, \u00bfsabe por qu\u00e9 fallan tan f\u00e1cilmente?He escrito este libro para intentar explic\u00e1rselo. No se trata del habitual tratado sobre teor\u00eda de n\u00fameros, algoritmos de clave p\u00fablica o firmas digitales, aunque tambi\u00e9n est\u00e1n explicados. Mi prop\u00f3sito es mostrar c\u00f3mo la criptograf\u00eda ha moldeado el comportamiento de industrias y modelos de negocio que usted utiliza asiduamente, combinando detalles t\u00e9cnicos con explicaciones cotidianas. A lo largo de las \u00faltimas dos d\u00e9cadas, sectores como la telefon\u00eda m\u00f3vil o la discograf\u00eda en DVD han sufrido profundas transformaciones, y en m\u00e1s de una ocasi\u00f3n la inseguridad de los sistemas de cifrado ha sido causa fundamental. Podr\u00e1 usted ver resueltas dudas como:\u00bfHasta qu\u00e9 punto los algoritmos criptogr\u00e1ficos GSM son seguros?\u00bfPor qu\u00e9 en los a\u00f1os noventa pillaron a Txiqui Benegas hablando de \u201cel enano\u201d o \u201cel one\u201d en su flamante Motorola?\u00bfC\u00f3mo es posible que haya tanto fraude en tarjetas de cr\u00e9dito, ahora que los chips los hacen invulnerables?\u00bfQu\u00e9 se han inventado los hackers de Boston o Londres para viajar gratis total con los nuevos bonos de transporte?\u00bfQu\u00e9 hay de cierto en los rumores de que los mensajes de WhatsApp est\u00e1n mal protegidos?\u00bfRealmente tantos usuarios utilizan 12345 como contrase\u00f1a?\u00bfPuede ser hackeado un marcapasos?\u00bfEs tan bueno Dan Brown cuando escribe libros sobre criptograf\u00eda?\u00bfQu\u00e9 tienen en com\u00fan la criptograf\u00eda y el asesino que dio origen a la saga de Harry el Sucio?\u00bfQu\u00e9 debo hacer si me roban la tarjeta de cr\u00e9dito?\u00bfPor qu\u00e9 las autoridades de Washington no pudieron alertar a tiempo a los mandos militares de Pearl Harbor sobre el inminente ataque?\u00bfPor qu\u00e9 tantos hackers odian a Sony y aman su PlayStation3?En serio, \u00bfdeber\u00eda cambiar mi contrase\u00f1a? Me gusta 12345, es f\u00e1cil de recordar. Tampoco es tan importante, \u00bfno?No es necesario que tenga conocimientos matem\u00e1ticos de alto nivel. Lo \u00fanico que necesita es su experiencia de usuario. Si, por el contrario, se queda con ganas de ampliar informaci\u00f3n, el libro incluye m\u00e1s de quinientas referencias digitales de todo tipo. Un clic en el lugar adecuado, y su lector de libros le llevar\u00e1 directamente a la fuente original.Y recuerde: 12345 no es una contrase\u00f1a v\u00e1lida. En serio.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Arturo Quirantes Sierra<\/p>\n","protected":false},"featured_media":65932,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[23],"product_cat":[10313,5808,5807,5806],"product_tag":[5960,5849],"class_list":["post-16874","product","type-product","status-publish","has-post-thumbnail","product_brand-epub-paradise","product_cat-arturo-quirantes-sierra","product_cat-ebooks","product_cat-epub","product_cat-espanol","product_tag-comunicacion","product_tag-tecnologia","desktop-align-center","tablet-align-left","mobile-align-center","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
