ABSTRACT:
A method and apparatus for providing a network computer with secure remote swapping to avoid transmitting active memory resident entities (such as data structures, pages, and segments) containing sensitive data in the clear. When a memory resident entity is created, it is entered in a Table of Secure Entities (TSE) if it requires security. The memory manager of the network computer checks the TSE for an entity before swapping it out to a network server. If the entity is in the TSE, the memory manager encrypts the contents of the entity using the public key from the network computer's SmartCard device. When reloading the entity, the memory manager uses the private key from the SmartCard to decrypt the contents of the entity.
