Podstawy kryptografii. Wydanie III

Marcin Karbowski

Przekonaj się, jak fascynująca jest kryptografia! Poznaj historię rozwoju kryptografii Opanuj jej matematyczne podstawy Rozpracuj najważniejsze algorytmy kryptograficzne Dowiedz się, jak zastosować je w praktyce Kryptografia to dziedzina nauki, której sedno stanowią sposoby bezpiecznego przekazywania informacji. Jest ona niemal tak stara, jak nasza cywilizacja, a dziś rozwija się w sposób niezwykle dynamiczny. Gdy tylko narodziły się pierwsze metody zapisu i komunikowania się, pojawiła się też konieczność zabezpieczenia informacji przed tymi, którzy mogliby wykorzystać je na niekorzyść osób dysponujących tymi informacjami. Od bezpieczeństwa ważnych informacji zależały często losy całych państw i narodów. O rozstrzygnięciach wielkich bitew nierzadko decydowały inteligencja i determinacja pojedynczych osób, które potrafiły odpowiednio skutecznie szyfrować (bądź też deszyfrować) nadawane (lub przechwytywane) komunikaty. O tej fascynującej dziedzinie wiedzy opowiada książka Podstawy kryptografii. Wydanie III. Wprowadza ona czytelnika w podstawowe zagadnienia kryptografii bez przygniatania nadmiarem teorii i skomplikowaną matematyką. Kusi za to barwnymi opisami i pasjonującymi przykładami "kryptograficznych wojen". Można dzięki niej poznać historię rozwoju technik szyfrowania informacji, matematyczne podstawy kryptografii, stojącą za nią teorię oraz praktyczne zastosowania tej nauki. Niezależnie od tego, czy chcesz poznać kryptografię na własny użytek, czy jest Ci to potrzebne w celach zawodowych, książka ta okaże się doskonałym przewodnikiem po świecie szyfrów, kluczy i algorytmów zabezpieczających dane. Znajdziesz w niej informacje na temat protokołów SSL i SSH, a także szczegółowy opis algorytmu SHA3. Przegląd klasycznych sposobów szyfrowania Matematyczne podstawy kryptografii Praktyczne zastosowanie mechanizmów matematycznych Teoria kryptoanalizy i informacji oraz jej praktyczne wykorzystanie Przegląd protokołów kryptograficznych Klucze publiczne i prywatne Zasady zabezpieczania danych, połączeń i systemów komputerowych Potwierdzanie tożsamości za pomocą podpisów elektronicznych Zabezpieczanie stron internetowych i szyfrowanie baz danych Naucz się chronić cenne dane!
