I’m pleased to report that after years of reading Bruce Schneier, I am finally catching on. A few weeks back at the Embedded Systems Conference I attended a lunch for startup companies and venture capitalists. One of the presenting companies, SecureRF, claimed to have invented a security protocol for resource-constrained systems (such as RFID devices) that was (a) cheap mathematically and (b) even more secure than existing security techniques.
I was skeptical. I even thought of blogging here or e-mailing Bruce, but just never found the time. Encryption is mathematically hard for reasons I had learned in grad school. The company’s hand-waving about a new faster way of doing it was either bullsh*t or a major cryptology breakthrough we should all be reading about elsewhere.
