Unformatted text preview: s can be computed by a set of n players in a way that will let all learn the value of the function, but any set of less than n/2 players will not get any additional information that does not follow from their own inputs and the value of the output information. For details, see [136, 334, 1288, 621]. Secure Circuit Evaluation
Alice has her input, a. Bob has his input, b. Together they wish to compute some general function, f (a,b), such that Alice learns nothing about Bob’s input and Bob learns nothing about Alice’s input. The general problem of secure multiparty computation is also called secure circuit evaluation. Here, Alice and Bob can create an arbitrary Boolean circuit. This circuit accepts inputs from Alice and from Bob and produces an output. Secure circuit evaluation is a protocol that accomplishes three things: 1. Alice can enter her input without Bob’s being able to learn it. 2. Bob can enter his input without Alice’s being able to learn it. 3. Both Alice and Bob can calculate the output, with both parties being sure the output is correct and that neither party has tampered with it. Details on secure circuit evaluation can be found in .
