Abstract: A system and method secure transactional data communicated over a wireless network in a store by obfuscating bona fide transactional messages in the message traffic flow. The system includes a load balancer coupled to a store host computer and a plurality of transactional terminals coupled to the store host computer through a wireless communication network. The load balancer monitors message traffic queues and message processing at the store host computer to determine possible dead time in the bandwidth of the wireless communication network. If the dead time is greater than a threshold, a bogus request message is generated and sent to one or more terminals in the system. In response to receipt of a bogus request message, a terminal activates a bogus message generator. The bogus message generator generates transactional messages with bogus customer, account, and transactional data therein.

Abstract: A PIN device utilizes a preferably removable IC card to store and process data to provide a tamper resistant PIN entry system. The IC card is a tamper resistant module that provides four functions for the PIN device. The IC card: stores secure data for the PIN device; provides authentication for verifying that the IC card can be trusted; provides a mechanism for the loading of secure data into the PIN device; and provides a mechanism to authenticate its identity to other parties. The subject PIN entry system allows for servicing of the PIN device in the field.
