What Is the Foundation of Cryptography and Its Key Principles?

TL;DR

The foundation of cryptography lies in three essential principles: confidentiality, integrity, and availability. Confidentiality protects information from unauthorized access; integrity ensures that data is altered only by authorized individuals; and availability guarantees continuous access for legitimate users. Understanding these principles is crucial for effective cybersecurity.
