How Encryption Keeps Your Data Safe

The video explores the evolution of encryption from ancient Spartan methods to modern digital ciphers. It explains classical ciphers like transposition and substitution, highlighting their weaknesses. The video discusses Claude Shannon's idea of alternating ciphers, which laid the foundation for modern cryptography. It also covers the development of digital ciphers, such as block and stream ciphers, and their importance in securing information today.
