RSA SecurID Token number symmetry
As my computer, for unknown reason, drops out of the VPN connection regularly I have to log on using this token quite often. And the more I have to look at the generated numbers, the more I get the impression that the tokens often generate "symmetric-looking" numbers. Just at the moment I'm looking at 568561. The next such ones (in a timeframe of about 8-10 minutes) are: 804508, 259825, 438858, 832738.
To me these numbers look not as random as they should, but of course I could be wrong and everything is really just coincidence. Is it really just randomness which causes so many codes with such a symmetric display and so many repeating numbers?
One could now begin to calculate the chances of two digits appearing twice in a collection of 6 digits. How high would the probability be?
I don't really know because I don't have enough time to investigate, but it leaves a curious feeling...
