Kryptografia
Dominik Robakowski
Kryptologia jest trudna? Może, ale na pewno nie z tą książką! Jeśli słowo "szyfr" budzi w Tobie przyjemny dreszczyk emocji, mamy dla Ciebie prawdziwą gratkę. Już za chwilę poznasz największe tajemnice ludzkości. Prezentowane w tej książce tajemnicze kody służyły dyplomatom, armiom pierwszej i drugiej wojny światowej, wreszcie zimnowojennym szpiegom. Były kamyczkami, które wywołały lawinę rewolucji informatycznej. Bez żadnej przesady - oto szyfry, które decydowały o losach świata. I wciąż o nich decydują. Kryptologia bardzo intensywnie się rozwija. Dziś jest wręcz niezbędna do naszego funkcjonowania. Warto poznać jej podstawy, tak samo jak wypada się orientować w historii, fizyce czy biologii - choćby po to, by być na bieżąco ze współczesną nauką. Poza tym szyfrowanie i deszyfrowanie stanowi znakomitą gimnastykę dla umysłu i dobry sposób na kreatywne spędzenie czasu. Co więcej, prezentowane sposoby ukrywania wiadomości mogą nadal służyć zgodnie ze swoim pierwotnym przeznaczeniem - do ukrywania tego, co niekoniecznie chcemy przekazać wprost...

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!

As agentic AI shifts from text generation to operational roles, it relies on the Model Context Protocol (MCP) to interface with databases and execute code. While MCP provides essential connectivity, it introduces a sophisticated attack surface. Practical MCP Security offers a hands-on framework for protecting these autonomous systems throughout their lifecycle.The book begins by deconstructing MCP architecture to establish a rigorous threat model, categorizing risks across supply chain integrity, runtime execution, and code-execution attack vectors. Readers will learn to map these vulnerabilities to testable security controls that mirror adversary behavior. It then details the technical implementation of OAuth 2.1 and scoped authorization, ensuring every interaction is authenticated and auditable.Beyond identity, the guide explores specialized threats like prompt injection, tool poisoning, and rug pull malicious updates. For enterprise production, it covers deployment hardening - including sandboxing, I/O validation, and secrets management - before addressing governance through RBAC, policies, and human-in-the-loop (HITL) mechanisms.Complete with Python implementations and verification checklists, this book provides the professional roadmap required to deploy agentic AI with institutional-grade security.
