Achieving autonomous fair exchange in ubiquitous network settings
<06> This paper presents pioneering work on autonomous fair signature/key exchange in emerging ubiquitous commerce (u-commerce). Existing approaches are ineffective for such exchange, as their design did not envisage this type of exchange scenario. To rectify the problem, the paper proposes the first autonomous fair exchange protocol. It is supported by several novel techniques and their integration, e.g. purpose-restricted encryption key certification and threshold verifiable and accountable proxy encryption. A rigorous analysis is also provided for the proof of the protocol security. The work is important for supporting the wide acceptance and deployment of u-commerce.
