| Sep 23, 2015 at 10:07 | comment | added | user3312054 | your answer looks interesting, however im not very clear with some parts of it. Firstly why do we need x, is that for uniqueness? and also when you say "anyone without the key can look at the first bits to see whose it is " do you mean verifying the token by 'i', and if yes, does that mean all tokens produced with key 'ki' will have the same bits at the beginning of the token?..thank you | |
