Risk Management for E-Cash Systems with Partial Real-Time Audit

We analyze “coin-wallet” and “balance-wallet” under partial real-time audit, and compute upper bounds on theft due to the fact that not all the transactions are audited in real time, assuming that every- thing else is perfect. In particular, we assume that the audit regime holds for innocent players...

Zusammenfassung:	We analyze “coin-wallet” and “balance-wallet” under partial real-time audit, and compute upper bounds on theft due to the fact that not all the transactions are audited in real time, assuming that every- thing else is perfect. In particular, we assume that the audit regime holds for innocent players. Let v be the maximum allowed balance in a wallet, 0 ≤ μ ≤ 1 be the fraction of transactions that are audited in real time in an audit round that includes overall n transactions. Assume one unit transactions. We show that for μ
