Here everyone agrees. > usb is a big hole. That's Randy's opinion. I have a different opinion - maybe because I have a good decade of experience with the protocol, maybe because I am a hipster, as Randy put it. :) > we want i/o to go through as small a hole as possible. I maintain that this philosophy is flawed for security devices as well as for others. I prefer structured low-level communication over byte stream parsers in all my security devices, because it removes a large portion of error-prone code not only in the device, but also in the host. I do admit that I too have fun writing such code, but that's not an argument, and I do not consider it more secure. //Peter _______________________________________________ Tech mailing list Tech@cryptech.is https://lists.cryptech.is/listinfo/tech
