Talk Title: Enigma and Bombe: how they encrypt and how they decipher in WWII

Most cybersecurity professionals probably are aware of the significant role of codebreakers in WWII, in particular the encryption device Enigma and the code-breaker Bombe that often appeared in popular media. So, what about the technical details? In this talk, I will describe the details of Enigma & Bombe, up to the point that we could simulate them. While the experiences on both machines likely shaped development of modern cryptography, we probably won’t need such electro-mechanical system anymore. Nonetheless, it would be a fun topic to kickstart this seminar series.


Ee-Chien Chang is an Associate Professor in the School of Computing at National University of Singapore (NUS). He received his PhD in Computer Science from New York University and was a postdoctoral fellow with DIMACS in Rutgers University and NEC Labs America. His research focuses on cybersecurity security and is particularly intrigued by cross-domain problems. His earlier works include multimedia security, such as image forensic, image watermarking and biometric cryptography, which is in the intersection of multimedia and applied cryptography. More recently, he has been investigating issues on security of machine learning under adversarial environment, and application of the hardware-based Trusted Execution Environment in the cloud. He has published in reputable conferences and journals. He is a lead-PI of National Cybersecurity R&D Laboratory (NCL), NUS, and deputy director of the Centre for Technology, Robotics, Artificial Intelligence & the Law (TRAIL), NUS.
