Rational Secret Sharing with Side Information in Point-to-Point Networks via Time-Delayed Encryption
secret sharing game theory rational cryptography time release cryptography
2010/10/21
In this paper, we give the first construction of a rational secret sharing protocol that is strict Nash (or Nash with respect to trembles) in the computational sense, works in a standard point-to-poin...
Improving the Round Complexity of VSS in Point-to-Point Networks
VSS Point-to-Point Networks Round Complexity
2008/5/28
We revisit the following question: what is the optimal round complexity of verifiable secret
sharing (VSS)?We focus here on the case of perfectly-secure VSS where the number of corrupted
parties t s...
