Abstract
We want to build a secure system in which customers of a bank can make transactions and be able to keep a proof of each transaction. We also want the system to satisfy (as far as possible) the following constraints (our ultimate purpose is to remove all physical money):
-
the customers are able to make transactions over the phone (just by exchanging messages),
-
no communication with the bank is required for a transaction,
-
no directory of customers is available.
Supported in part by a grant from NSERC.
