The message you wish to send is converted to a cipher text that appears to be gibberish unless you know the secret to unlocking it. WebWe identify a broad class of multi-party cryptographic computation problem, including problems subject to the partial-information constraints of the "mental games" of Goldreich, Micali, and Wigderson [24]. In order to solve any cryptographic computation problem, we develop new techniques that can be implemented efficiently in the public-key model. crystal clear wand
