Secure Multiparty Computation
A function is private if there exists a protocol that is secure; that is, no party can learn any additional information about the other parties’ inputs other than what follows from their own input and the function’s output. Previous studies have investigated multiparty computation with broadcast communication, but broadcast communication does not fully capture all secure multiparty protocols. W...
متن کاملSecure Multiparty Computation
Assume a number of parties want to compute a public function F (x1, . . . , xn) = (y1, . . . , yn). All of them want to get the correct answer, but none of them are willing to expose their secret inputs to other parties. One way to achieve this requirement is to implement the secure multiparty computation protocols. In this paper, we will make a brief introduction to secure multiparty computati...
متن کاملScalable Secure Multiparty Computation
We present the first general protocol for secure multiparty computation which is scalable, in the sense that the amortized work per player does not grow, and in some natural settings even vanishes, with the number of players. Our protocol is secure against an active adversary which may adaptively corrupt up to some constant fraction of the players. The protocol can be implemented in a constant ...
متن کاملSecure Multiparty Computation from SGX
Isolated Execution Environments (IEE) offered by novel commodity hardware such as Intel’s SGX deployed in Skylake processors permit executing software in a protected environment that shields it from a malicious operating system; it also permits a remote user to obtain strong interactive attestation guarantees on both the code running in an IEE and its input/output behaviour. In this paper we sh...
متن کاملSecure Multiparty Computation Goes Live
In this note, we report on the first large-scale and practical application of multiparty computation, which took place in January 2008. We also report on the novel cryptographic protocols that were used.
