Abstract

In the letter we will consider some of the security problems that arise within a large electronic fund transfer point of sale (EFTPOS) system, paying particular attention to the difficulties of key management. In particular, we will introduce the concept of a transaction key which provides automatic key management at almost no extra cost.
