ENCRYPTION SYSTEM AND METHOD FOR LEGACY DEVICES IN A RETAIL ENVIRONMENT |
摘要 |
A security module used in a retail establishment has two zones of operation. The first zone uses a first encryption scheme between data entry point devices, such as a PIN keypad and the security module. The second zone uses a second encryption scheme between the security module and the host network computer. Both the local encryption scheme and the host encryption scheme may be selectively and independently switched from a legacy encryption scheme to a new encryption scheme to accommodate evolving encryption requirements. |
