US Patent:

49454684, Jul 31, 1990

Filed:

Feb 1, 1988

Appl. No.:

7/150965

Inventors:

Mark E. Carson - Rockville MD
Abhai Johri - Gaithersburg MD

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 900
H04K 100
G06F 1214
G06F 944

US Classification:

364200

Abstract:

When the user is logged on to a processor running multiple virtual terminals and he presses the Secure Attention Key, the existing virtual terminal processes are not destroyed. Instead, the invention creates a new virtual terminal, establishes a trusted path for the new virtual terminal, makes the new virtual terminal the current virtual terminal, and then runs the trusted process in the new virtual terminal.

International Classification:

H04L 900

US Classification:

380 25

Abstract:

In the remote trusted path invention, secure systems may provide a mechanism for the user to establish a trusted path for direct communication with the system's trusted computing base for security-critical operations. This invention allows users to request such a trusted path from remote systems using a new TELNET option and command, in a system-independent, confirmed, backward-compatible manner. It also describes how to implement remote support for such a trusted path in systems which use a Secure Attention Key mechanism such as Secure AIX.

International Classification:

H02K 7/116

Abstract:

A multi-degree-of-freedom electromagnetic machine that may be operated as a motor, a generator, or a motor-generator, includes a first structure and a second structure. The first structure comprises a first conductor, a second conductor, and a third conductor, each of which follows a different trajectory. The first, second, and third conductors together form a general shape of a surface. The second structure is disposed adjacent to the first structure and includes a magnet that emanates a magnetic field. The magnet has at least one of its magnetic poles facing the surface. A Lorentz force affects relative movement between the first structure and the second structure when the magnetic field that emanates from the at least one magnetic pole interacts with electrical currents within any of the electrical conductors.
