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.

comment Are there any simple and yet secure encryption algorithms?
@archie: Did you maybe mean to link to the Simeck tweet on p. 23 of "Revisiting Counter Mode to Repair Galois/Counter Mode and Simeck: An Authenticated Cipher Design"?
