An Optimistic NBAC-Based Fair Exchange Method for Arbitrary Items
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
This paper proposes a novel fair exchange method that enables parties to fairly exchange arbitrary items in an optimistic manner. ...
This is achieved by realizing an optimistic non-blocking atomic commitment (NBAC) protocol between two smartcards and adapting the known result that fair exchange can be reduced to NBAC among trusted processes ...
This paper proposes a novel optimistic fair exchange method that fairly exchanges arbitrary items in an optimistic manner with no restriction on items being exchanged. ...

Our construction of NBAC functionality (namely FNBAC) is exactly equivalent to the NBAC definition; it is formally proved that a protocol UC-securely realizes FNBAC if and only if the protocol is an NBAC ...
When using the optimistic NBAC protocol [8] as the NBAC part of this algorithm, this exchange realizes optimistic (strong) fair exchange of arbitrary items while other known optimistic protocols can ...

Optimistic fair exchange For two parties, Asokan et al. [48] proposed a 4-message optimistic fair exchange scheme that ensures termination. ...
Both works focus on synchronous NBAC, while our study is for an arbitrary (asynchronous) system as well as an arbitrary combination of properties of NBAC. ...
