Secure Multi-Party Computation without Agreement
2005
Journal of Cryptology
Preserved Fulltext
That is, we show that secure multi-party computation for this definition can be achieved for any number of corrupted parties and without a broadcast channel (or trusted preprocessing phase as required ...
We remark that it was accepted folklore that the use of a broadcast channel (or authenticated Byzantine agreement) is actually essential for achieving meaningful secure multi-party computation whenever ...
Security in multi-party computation. A number of different definitions were proposed for secure multi-party computation (e.g., [38, 26, 6, 27, 1, 34, 9] ). ...

Indeed, we prove that secure multi-party computation can be achieved for any number of corrupted parties and without a broadcast channel (or trusted preprocessing phase as required for running authenticated ...
In particular, this is true for the whole body of work of secure multi-party protocols in the case that 1/3 or more of the parties are corrupted. ...
Thus, the lower bounds for Byzantine agreement indeed do not imply lower bounds for secure multi-party computation. ...

The scheme provides therefore an efficient and elegant way of multi-party key agreement without key establishment data transmissions. ...
In this paper, we present the novel concept of fractional public keys and an efficient zero-round multi-party Diffie-Hellman key agreement scheme that is based on fractional public keys. ...
Hence, the scheme provides secure multi-party key agreement with the advantage that secret group keys can be computed without user interaction and key establishment data transmissions. ...
