Cryptography and Encryption Fundamentals

In a modern power system, electricity doesn’t just flow through wires—it flows through data. Cryptography and Encryption Fundamentals provides a practical introduction to the principles that underpin secure digital communications, trust and data protection. The session explains how cryptographic techniques are used to protect data confidentiality, integrity, authenticity, and non-repudiation in modern digital systems. Aimed at technical staff across a range of disciplines, the presentation covers core topics including encryption and decryption concepts, symmetric /asymmetric cryptography, hashing, file integrity, and passwords, helping unpack terms often heard and used every day but not fully understood. By protecting communication and ensuring trust, cryptography forms a silent shield around power systems, helping maintain reliability, safety, and stability in an increasingly digital and connected world.
