Keeping Secrets with Public Communication
نویسنده
چکیده
Given some deal of cards, it is possible to communicate your hand to another player without yet another player learning any of your cards. Every solution to this problem consists of a sequence of safe communications, an interesting new form of update. Certain unsafe communications turn out to be unsuccessful updates. Each communication can be about a set of alternative card deals only, and even about a set of alternatives to your own hand only. We solve a speci c cards problem and summarily discuss some combinatorial issues that are not of logical interest. Generalizations appear to be relevant to cryptology.
