comment Simplied DES why 10-bit key?
Mark, are you maybe referring to one of the simplified variants of DES mentioned at en.wikipedia.org/wiki/Data_Encryption_Standard#Simplified_DES ?

comment Coin flipping with limited communication between participants
@Victor: You are right. As often happens to all programmers, I have a first part of something that solves part of the problem, and then I add a second part that solves the rest of the problem; and later I realize that this second part can be used to solve the entire problem and I don't need the first part any more.

comment Is the one-time-pad a secure system according to modern definitions?
@CodesInChaos: I realize the original title "Has the one-time pad been broken?" was a little provocative, but I think "Does the one-time-pad meet modern security definitions?" is ambiguous. The answer is either trivially "no" (a OTP doesn't do or meet anything; people and machines do things and meet people) or trivially yes (The modern definition of a OTP has critical details not present in early cryptography definitions, and of course a real OTP matches that definition, even though other things that people might mistakenly call a OTP do not). Feel free to tweak the title further.
