You are overlooking the main point that this is a _timing_ attack. Unless ... Just beware of people with extremely precise stopwatches at key signing parties ;>
Hold on, you *never* sign directly at key signing parties! Never take your key where: - it could be stolen - you suspect others may wish to influence your signing - somebody might spy your passphrase (hidden cameras in ceiling) You take fingerprints, and sign when you get back home. Re the timing subject, do you think it'd make a good party trick? * Think of a number between 20 and 30. * for 4-5 numbers a, "Multiply the orignal number by <a>" * the number you are thinking of is <number> Now, anybody have statistics for mental arithmetic?
