Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 900

US Classification:

713200, 713201

Abstract:

The present invention provides a method and system for securing a computer. The method includes providing a zone of authorized operation for the computer; determining if a possessor of the computer is authorized to have possession when the computer and the possessor leaves the zone of authorized operation and pass through a portal; and allowing continued access to the computer without requiring a password if the possessor is authorized. The method and system is transparent to the possessor and provides no advantage in hiding the computer from the portal. This method and system may be easily applied in a corporate environment and is particularly apt for securing mobile computer systems.

US Classification:

709229, 380273, 380277, 713167, 713183

Abstract:

A system, method, and program for managing a user key used to sign a message for a data processing system having an encryption chip are disclosed. A user is assigned a user key. In order to encrypt and send messages to a recipient(s), the messages are encrypted with the user key. The user key, in turn, is encrypted with an associated key. The associated key is further encrypted using an encryption chip key stored on the encryption chip. The encrypted messages are communicated to a recipient to validate an association of the user with the encrypted messages. The associated key is decrypted with the encryption chip key. The user key is decrypted with the associated key, and the messages are decrypted with the user key. Thereafter, validation of the association of messages with the user is removed by revoking the associated key. In a preferred embodiment, encryption resources are centralized in a server system having the encryption chip.

US Classification:

702186, 702185, 702188, 702189

Abstract:

An apparatus, system, and method are disclosed for memory configuration analysis. A classification module determines an overall performance of an array of memory devices in a computer memory , wherein overall performance has a substantially inverse relationship with a highest quantity of members of a subset of the array and a substantially direct relationship with an individual performance capability of the members. A counting module takes a count of members of the array whose individual performance capability varies in a selected direction from the overall performance of the array. A comparison module takes a selected action such as issuing a memory configuration warning if the count crosses a predetermined threshold comprising a predetermined percentage for comparison with the count, as qualified by the individual performance capability, divided by an unqualified count of members of the array.

US Classification:

711114, 711 5, 711104, 711105, 711170

Abstract:

An apparatus, system, and method are disclosed for memory upgrade optimization. A requirements module receives one or more of a capacity upgrade goal for an overall capacity of the array and a performance upgrade goal for an overall performance of the array. An analysis module identifies a first potential capacity change that can be achieved at a lower overall performance and a second potential capacity change that can be achieved at a higher overall performance. A reconfiguration module generates one or more of a first reconfiguration recommendation calculated to yield an overall capacity improvement that takes into consideration the capacity upgrade goal and the first potential capacity change and a second reconfiguration recommendation calculated to yield an overall performance improvement that takes into consideration the performance upgrade goal and the second potential capacity change.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L009/00

US Classification:

705063000, 700286000, 702062000

Abstract:

In a central system for receiving reports of utility usage from a number of remote meters, a provision is made for assuring that a received report has actually been transmitted from a meter that has been registered with the central system. During the registration process, the meter transmits its public cryptographic code to the central system. With each report of utility usage, the meter sends a version of a message encrypted with its private cryptographic key. The central system decrypts this message with the meter's public key. If it matches an unencrypted version of the message it is known that the meter sent the report. The unencrypted message may be generated by the central system and transmitted to the meter in a request for a report, or it may be generated by the meter and sent along with the encrypted version.

US Classification:

705 14

Abstract:

A method for enticing computer users to return to an electronic commerce portal is disclosed. In response to a user registering to a merchant server for the first time, a unique number is associated with the user. Hardware information is then obtained from a computer utilized by the user. A digital certificate is generated by encrypting the unique number along with the obtained hardware information. The digital certificate is subsequently sent to the user computer for generating a unique customer number to be displayed on a web page of the user computer. On a periodic basis, the merchant server sends a master number to the user computer to be displayed on a web page of the user computer. In response to a notification of the master number matches the unique customer number on the user computer, a prize claiming process can be initiated.
