Cryptography and Satellite Navigation is a comprehensive guide that offers a wide-ranging yet approachable introduction to the world of cryptography, with a particular focus on its role in navigation. In an increasingly connected world, cryptography serves as the cornerstone of secure communication, safeguarding information across countless cyber and navigation applications. The book includes a thorough explanation of the three primary cryptographic methods. Symmetric ciphers provide confidentiality through shared keys, while hashes play a crucial role in ensuring the integrity of information. Asymmetric, or public key cryptography, introduces a level of security through confidentiality and authentication, uniquely using private information to establish digital signatures. The book contains an insightful exploration of quantum computing and its profound implications for the future of cryptography
