Communication-Efficient Unconditional MPC with Guaranteed Output Delivery
Multiparty Computation Information-theoretic Cryptography Communication Complexity
2019/6/5
We study the communication complexity of unconditionally secure MPC with guaranteed output delivery over point-to-point channels for corruption threshold t
Fairness Versus Guaranteed Output Delivery in Secure Multiparty Computation
secure multiparty computation theoretical foundations complete fairness
2016/1/7
In the setting of secure multiparty computation, a set of parties wish to compute a joint
function of their private inputs. The computation should preserve security properties such as
privacy, corre...
Constant-Round MPC with Fairness and Guarantee of Output Delivery
MPC Threshold FHE Learning with error
2015/12/31
We study the round complexity of multiparty computation with fairness and guaranteed output
delivery, assuming existence of an honest majority. We demonstrate a new lower bound and a matching
upper ...
Tampering with the Delivery of Blocks and Transactions in Bitcoin
Bitcoin Scalability P2P networks
2015/12/29
Given the increasing adoption of Bitcoin, the number of transactions and the block sizes within the system are only expected to increase. To sustain its correct operation in spite of its ever-increasi...
Towards Provably-Secure Timed E-Commerce:The Trusted Delivery Layer
secure electronic commerce non-repudiation timestamp
2009/4/14
Certified exchange of messages is an essential mechanism for e-commerce; the timing aspects (timeouts
and timestamps) are very important for practical applications. However existing formal methods fo...
Unfairness of a protocol for certified delivery
Cryptographic protocols Fair exchange Non-repudiation
2009/1/15
Recently, Nenadi¶c et al. (2004) proposed the RSA-CEGD protocol for
certified delivery of e-goods. This is a relatively complex scheme based
on verifiable and recoverable encrypted signatures (...
Evidences of delivery are essential for resolving (and avoiding) disputes on delivery of messages, in classical as well as electronic commerce. We present the first rigorous specifications and provabl...
