Beyond Cryptography Theater -- with Hands-On Training


Many products scramble data in minor ways to make it look encrypted but don't actually protect secrets from serious attackers. Examples are security theater in Windows, Android apps, Web browsers, and Web apps along with good examples of proper encryption in similar use cases. Developers need to do better and managers need to expect more. Both of those improvements are achievable with just a little more education.

Hands-on portion:

Participants will compete individually or in teams to solve obfuscation and encryption challenges with a live CTF-style scoreboard. No additional computer equipment or application is required beyond a Web browser because everything you need is in the cloud.


Doors open at 4 pm
Registration ends at 4:10 pm
4:10 - 4:40 pm Presentation
4:40 - 5:30 pm CTF
5:30 - 6:00 pm Networking

Event ends at 6 pm.


For the hands-on portion, participants will need a device that can connect to the campus WiFi and provide their own back up power source. All technical levels are welcome to try the CTF in teams or individually.
