Modern Cryptography
Modern cryptography is a branch of computer science and mathematics focused on designing and analyzing secure communication protocols and systems in the presence of adversaries. It involves techniques such as encryption, digital signatures, and key exchange to ensure data confidentiality, integrity, and authenticity. Unlike classical cryptography, it relies on rigorous mathematical foundations and computational hardness assumptions to provide provable security.
Developers should learn modern cryptography to build secure applications that protect sensitive data, such as in financial transactions, healthcare systems, and communication platforms. It is essential for implementing features like end-to-end encryption, secure authentication, and data privacy compliance (e.g., GDPR, HIPAA). Understanding these concepts helps prevent common vulnerabilities like data breaches and man-in-the-middle attacks.
