I’ve always been fascinated and terrified by encryption algorithms. They’re the backbone of our web based economy and provide companies and users with some level of privacy. Of course nothing is fool proof, not even the most advanced of our encryption algorithms. It seems day after day we hear about hacker collectives that exploit a flaw in a system and extracted hashed and encrypted data that everyone fears might be cracked. I say fears, because most no one understands how these encryption algorithms work and how they really protect our data. Where are they weak and how do they shine?

For my research studio on algorithms I’ve decided to concentrate on understanding and implementing some encryption and decryption algorithms as well as playing around with some advanced mathematics, just so I can get a better idea of what it is we need in applications and to protect ourselves in an increasingly open (to spy on) world.

For this purpose, I’ve begun reading The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography as a primer for understanding modern cryptography before I start reading some more advanced texts like Understanding Cryptography: A Textbook for Students and Practitioners.

It was surprising to learn that the origins of cryptanalysis can be traced to the Muslim world after the birth of Islam. Considering the other numerous breakthroughs in the areas of arts, science and mathematics pioneered by those early Muslims, this shouldn’t have been a surprise but it was.

Hoping to find many more pleasant little surprises in the history and the code before I’m done.
