摘要

The system and method for tranferring secured messages between spaced locations uses a pair of encryption/decryption keys for the data-transfer session that are independently generated at each location from information that is in storage at each location. After each data-transfer session, selected information in storage at each location is changed so that the storage medium may not be duplicated and used by another user without the essential information from the authorized user.
