Abstract: A mechanism for mutual authorization of a secondary resource in a grid of resource computers is provided. When a primary resource attempts to offload a grid computing job to a secondary resource, the primary resource sends a proxy certificate request to the user machine. Responsive to a proxy certificate request, the user machine performs authorization with the secondary resource. If authorization with the secondary resource is successful, the user machine generates and returns a valid proxy certificate. The primary resource then performs mutual authentication with the secondary resource. If the authorization with the secondary resource fails, the user machine generates and returns an invalid proxy certificate. Mutual authentication between the primary resource and the secondary resource will fail due to the invalid proxy certificate. The primary resource then selects another secondary resource and repeats the process until a resource is found that passes the mutual authorization with the user machine.

Abstract: A system and method for providing an authentication code across a network for use in authentication of documents, such as printed lottery tickets. The system includes document-printing terminals that include a key that is used in a mathematical function with the bet information for a specific-game entry to generate a document code that is sent to a central server. The central server stores the received document code and then generates an authentication code for the document desired to be printed at the terminal, and sends the authentication code back to the terminal for printing on the issued document. The authentication code can be a further mathematical processing of the document code. Verification of the document occurs from comparison of the authentication code on the document and stored authentication and/or document codes at the server.

Abstract: Authentication methods are used to authenticate, a device1 having an ESN1 (electronic serial number), a device2 having an ESN2, and/or a user of the devices. In one implementation, device1 receives the ESN2 in a near-field signal; derives an authentication result as a function of the ESN1 and ESN2; and sends the authentication result to an authenticator device to use in completing authentication. Authentication is confirmed when the device1 authentication result matches an authentication result independently generated by the authenticator device, which is provisioned with the ESN1 and ESN2. In a second implementation, device1 generates a RAND1 (random number) and sends the RAND1 to device2 over a near-filed link. An authenticator device confirms authentication upon receiving the same RAND1 from both device1 and device2.

Abstract: A boot method an apparatus are described which reduce the likelihood of a security breach in a mobile device, preferably in a situation where a reset has been initiated. A predetermined security value, or password, is stored, for example in BootROM. A value of a security location within FLASH memory is read and the two values are compared. Polling of the serial port is selectively performed, depending on the result of such comparison. In a presently preferred embodiment, if the value in the security location matches the predetermined security value, then polling of the serial port is not performed. This reduces potential security breaches caused in conventional arrangements where code may be downloaded from the serial port and executed, which allows anyone to access and upload programs and data in the FLASH memory, including confidential and proprietary information.

Abstract: Techniques are described herein for securely prompting a user to confirm sensitive operations, input sensitive information or the like. The techniques include receiving or intercepting calls from applications to prompting routines. When a call to a prompting routine is received or intercepted a hint may be provided to the user to switch to a secure desktop. When the user switches from the user desktop to the secure desktop the particular prompt is displayed. The input to the prompt is received on the secure desktop and verified to have been provided by the user. The user input or a representation of the input is then returned to the application running on the user desktop. Using these techniques, interception of prompting messages by malware does not result in sensitive information being revealed. Furthermore, spoofing of new messages by malware does not lead to the dismissal of critical prompting.

Abstract: Various technologies and techniques are disclosed that provide a centralized model to assign, monitor, and manage security on home electronic devices. A three-dimensional security matrix uses a role-based model that allows users to map security into groupings. Users can be assigned security levels based on application role (what activity is involved), user role (what each family member or guest is allowed to do), and device role (what this device is allowed to do while preserving system integrity). An authorization service determines whether a particular activity requested by the user should be granted or denied based upon whether the user has authorization to access the particular activity and whether the particular device can support the particular activity without comprising the security of the network.

One method may include determining whether a given key has previously been loaded to a trusted platform module (TPM), loading the given key to the TPM and generating a key cache object corresponding to the given key if the determining step determines the given key has not previously been loaded to the TPM and restoring the given key to the TPM based on the key cache object corresponding to the given key if the given key has previously been loaded. Another method may include extracting a key from a TPM if the TPM does not have sufficient memory to load a new key, the extracted key corresponding to a least frequently used key cache object within the TPM. Another method may include restoring a key to a TPM, the restored key having been previously loaded to and extracted from the TPM.

Abstract: A medical ad hoc wireless network (10) is deployed in a healthcare medical facility surrounding individual patients and including wireless nodes (A, B, . . . , Z). Before deployment, each node (A, B, . . . , Z) is pre-initialized with a public key certificate (22) and offers a trust and symmetric key distribution service (32). In joining the ad hoc network (10), a node (B) authenticates and registers to one randomly self-chosen node (A) by using certified public keys (20). Such node (A) becomes Trusted Portal (TPA) of the node (B). The node (B) dynamically registers to a new self-chosen TP node when its old TP node leaves the ad hoc network (10). The network (10) supports symmetric key authentication between nodes registered to the same TP node. Additionally, it supports symmetric key authentication between nodes registered to different TP nodes.

Abstract: The present invention provides a method that allows three parties to mutually authenticate each other and share an encrypted channel. The invention is based on a novel twist to the widely used two party transport level SSL protocol. One party, typically a user at a browser, acts as a man in the middle between the other two parties, typically two web servers with regular SSL credentials. The two web servers establish a standard mutually authenticated SSL connection via the user's browser, using a novel variation of the SSL handshake that guarantees that a legitimate user is in the middle.

The Web-Server system provides a filter component for identifying and discarding non-SOAP requests as well as an access control manager for providing authentication examination for incoming SOAP-requests. After successful passing these components the SOAP-request is used for updating the existing configuration data file.

Abstract: System and method for providing secure resource management. The system includes a first device that creates a secure, shared resource space and a corresponding root certificate for the shared space. The first device associates one or more resources that it can access with the shared space. The first device invites one or more other devices to join as members of the space, and establishes secure communication channels with the devices that accept this invitation. The first device generates a member certificate for each accepting device, and sends the root certificate and the generated member certificate to the device through the secure channel. These devices may then access resources associated with the shared space by presenting their member certificates. Further, members of the shared space may invite other device to join the space, and may create member certificates in the same manner as the first device.
