Notes | The submission does not seem to be revised to reflect how the recommended changes in the parameter choices will affect the protocol size. (Signature sizes should probably change from 75 and 67 to 81).Signature sizes of 131 and 182 are just a guess.Protocol size for Level 3 and 5 do not seem to be explicitly reported on the proposal. Note 4: There seems to be some conflict between the protocol size numbers in “Limitations” paragraph and the tables. |
