We present a new compact verifiable secret sharing scheme,
based on this we present the first construction of a homomorphic UC
commitment scheme that requires only cheap symmetric cryptography,
exc...
The Round Complexity of General VSS
Round Complexity VSS Non-threshold Byzantine Unbounded Computing Power
2010/11/30
The round complexity of verifiable secret sharing (VSS) schemes has been studied extensively for threshold adversaries. In particular, Fitzi et al. showed an efficient 3-round VSS for $n \geq 3t+1$ \c...
Communication Efficient Perfectly Secure VSS and MPC in Asynchronous Networks with Optimal Resilience
Verifiable Secret Sharing Multiparty Computation
2010/1/18
Verifiable Secret Sharing (VSS) is a fundamental primitive
used in many distributed cryptographic tasks, such as Multiparty Computation
(MPC) and Byzantine Agreement (BA). It is a two phase (sharing...
On Round Complexity of Unconditionally Secure VSS
Verifiable Secret Sharing Error Probability Information Theoretic Security

In this work, we initiate the study of round complexity of unconditionally secure weak secret
sharing (UWSS) and unconditionally secure veri¯able secret sharing (UVSS) 1 in the presence of an
a...
Adaptively Secure Feldman VSS and Applications to Universally-Composable Threshold Cryptography
Adaptively Secure Feldman VSS Universally-Composable Threshold Cryptography
2009/3/26
We propose the first distributed discrete-log key generation (DLKG) protocol from
scratch which is adaptively-secure in the non-erasure model, and at the same time completely
avoids the use of inter...
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...
