  • Infrastructure method and system for authenticated dynamic security domain boundary extension
    Patent number: 7469417
    Abstract: A method and system for authenticated dynamic extension of security domain boundaries includes high security domain extension instructions for sequentially and dynamically forming an extended high security domain (133) through a protected communication path (128). The protected communication path (128) extends from a first computer (10) associated with a high security domain (80) into a second computer (10) associated with low security domain (120). The method and system establish the extended high security domain (133) within the second computer (10). A protected communication path (128) forms an isolation barrier (131) separating the extended high security domain (133) from other objects (126) within the low security domain (120). Authentication instructions (146) temporarily 20 authenticate at least one object (132) associated with the low security domain (120).

  • Infrastructure method and system for authenticated dynamic security domain boundary extension
    Publication number: 20040260941
    Abstract: A method and system for authenticated dynamic extension of security domain boundaries includes high security domain extension instructions (144) for sequentially and dynamically forming an extended high security domain (133) through a protected communication path (128). The protected communication path (128) extends from a first computer (10) associated with a high security domain (80) into a second computer (10) associated with low security domain (120). The method and system establish the extended high security domain (133) within the second computer (10). A protected communication path (128) forms an isolation barrier (131) separating the extended high security domain (133) from other objects (126) within the low security domain (120). Authentication instructions (146) temporarily authenticate at least one object (132) associated with the low security domain (120).
