20080230609SMART CARD SESSION OPTIMIZATION - A method is provided for facilitating communications between a computer device and a smart card reader having an associated smart card. The computer device includes a smart card resource manager and a smart card reader service, the smart card reader service acting as a relay for commands between the smart card resource manager and the smart card reader. The method comprising the smart card reader service: (a) receiving from the smart card resource manager a first command for placing the smart card in a first state and relaying the first command to the smart card reader; (b) receiving a second command from the smart card resource manager for placing the smart card into a second state and a third command from the smart card resource manager for placing the smart card into the first state; and (c) determining if the smart card was in the first state prior to receiving the second command, and (i) if the smart card is determined to have been in the first state then forgoing relaying the second command and the third command to the smart card reader, and (ii) if the smart card is not determined to have been in the first state, then relaying the second command and the third command to the smart card reader.09-25-2008
20090001160SYSTEM AND METHOD FOR IMPROVING SMART CARD READER RECONNECTIONS - Communications between a computing device and a smart card reader configured for communication with a smart card are facilitated through the use, by the computing device, of a smart card resource manager and a smart card reader service. The smart card reader service acts as a relay for commands between the smart card resource manager and the smart card reader. Appropriate configuration of the smart card reader service obviates a redundant downloading of certificates from smart card to computing device subsequent to loss of a connection between the computing device and the smart card reader. However, upon re-establishing a previously lost connection to a smart card reader and determining that a communication link between a smart card and the smart card reader has been ended and reestablished during the loss of connection, the smart card reader service may indicate to the smart card resource manager that smart card is absent and, subsequently, that the smart card is present.01-01-2009
20090014519SMART CARD SET PROTOCOL OPTIMIZATION - A method of facilitating communications between a computer device and a smart card reader having an associated smart card, the computer device including a smart card resource manager and a smart card reader service, the smart card reader service acting as a relay for commands between the smart card resource manager and the smart card reader, the method comprising: receiving from the smart card resource manager a first command for setting a protocol for communications with the smart card; and responding, prior to receiving a reply from the smart card to the first command, to the smart card resource manager with a message indicating that the smart card has successfully received the first command.01-15-2009
20090144540CERTIFICATE MANAGEMENT WITH CONSEQUENCE INDICATION - A certificate management operation request is managed on a device, access to which is governed by an authentication certificate. Upon receiving a request to perform a certificate management operation on a certificate, a consequence of performing the certificate management operation is determined and the consequence is indicated via a user interface of the device. For example, anytime a user attempts to use a certificate management application to delete, distrust or revoke a certificate, it is determined whether the certificate meets certain criteria, such as the certificate being the authentication certificate or being in the certificate chain of the authentication certificate. If the certificate meets the criteria, the user may be notified of a lack of permission to perform the requested operation and the operation may be prevented from completing. Alternatively, the user may be permitted to confirm the instruction to perform the requested operation, and the operation may be completed.06-04-2009
