FairCASH: Concepts and Framework
Yen Choon Ching, Heinz Kreft · 2008
This paper presents the framework for a true digital cash based payment system. The significant difference of this system as compared with previous system is that the value token is transferable among the users. This is achieved by using a tamper-resistant hardware to protect the value token. As a consequence of non-existing tamper-proof hardware, various measures are built into the system to detect and isolate fraud.
