Improving Cut-and-Choose in Verifiable Encryption and Fair Exchange Protocols using Trusted Computing Technology
Cut-and-Choose Verifiable Encryption Fair Exchange Protocols Trusted Computing Technology
2009/9/11
Cut-and-choose is used in interactive zero-knowledge protocols in which a prover answers a series
of random challenges that establish with high probability that the prover is honestly following the d...
Constructing Optimistic Fair Exchange Protocols from Committed Signatures
Committed signature scheme optimistic fair exchange protocols strong RSA assumption
2009/4/9
In PODC 2003, Park et al. [32] first introduce a connection
between fair exchange and sequential two-party multi-signature scheme
and provide a novel method of constructing fair exchange protocol by...
AbstractThis paper introduces a natural paradigm for fair exchange protocols, called ID-based partial proxy signature scheme. A security model with precise and formal definitions is presented, and an ...
