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.
