Abstract: A method and system for providing authentication of a user to a first peripheral device connected to a host computer using an authentication of the user on a second peripheral device, thereby allowing the user access to both devices through a single authentication. A security function on the second peripheral device is used to create an authorization phrase. Subsequent accesses to the first peripheral device requires the second peripheral device to re-create the same authorization phrase thereby demonstrating that the same second peripheral device is being used to access the first peripheral device and that a user was successfully authenticated to the second peripheral device. Other systems and methods are disclosed.

Abstract: A client-side application extension executable on a host computer from within a web-browser having the capability of executing at least one web-browser add-on to provide a user access to a smart card, connected to the host computer having a smart card resource manager, via the web-browser. The web-browser extension has instructions to direct the central processing unit to access data on the smart card via a web-browser and platform independent interface module and a web-browser and platform dependent wrapper module connected to the web-browser and platform independent interface module and to the smart card resource manager having a function processing module operable to receive a call to the at least one function for accessing data on the smart card and for transforming the function call into a corresponding call to the smart card resource manager.

Abstract: A system and method for establishing uniqueness in type definition names. Each application vendor has associated therewith a unique data sequence. The data sequence is combined with the type definition name and then a digital operation is performed to produce a unique digital identifier that is used in place of the type name.

Abstract: Updating the access control of a smart card at multiple points of the smart card life cycle. The system and method for updating the access control mechanisms during the smart card life cycle includes implementing an interface having a method for providing access control and a method for registering an access manager as an active access manager. In response to a request to register an access manager, the system and method executes the method for determining whether registering the access manager may be allowed.

Abstract: A system and method of operating a device to securely update the control firmware controlling the device. Downloading a firmware update package to a first microcontroller of the device. Determining a firmware update portion and an encrypted hash portion of the firmware update package wherein the encrypted hash portion is cryptographically signed by a signatory. Confirm that the encrypted hash portion conforms to the firmware update by independently computing the hash of the encrypted firmware update portion on the first microcontroller and comparing that value to the signed hash. Other systems and methods are disclosed.

Abstract: A system and method of operating a device connected to a host computer in a manner to preserve knowledge of logon authentication status to the host computer. Upon initialization of the device perform a pattern matching operation of an instruction sequence received by the second microcontroller. When the instruction sequence matches a prestored sequence indicative of performance of a logon process on the host computer tracking a logon state by the second microcontroller. Exchanging the logon state between the second and first microcontrollers such that when the second microcontroller resets, the second microcontroller may recover the logon state from the first microcontroller. Other systems and methods are disclosed.

Abstract: Secure authentication of a user on a host computer to a web server including a security device acquiring trust or a security context from the web server. The security device is operable of providing an X.509 certificate to a browser plug-in on the host computer. The browser plug-in on the host computer performing authentication of the security device and in response providing user credentials to the security device. The security device performing authentication of the user and requests a security context from the web server. In response, the web server provides a security context to the security device. The security device delegates the web server trust by transmitting the context to the host computer and enabling the user to securely access resources on the web server.

Abstract: Patching of software application. A software application is stored on a smart card as partitions and is loaded from the smart card into the memory of a host computer to which the smart card is connected. The software application is executed on the host computer; which using the instructions of the software application establishes a communications channel between the software application and a remote patch server containing a patch for at least one partition of the software application. Upon detecting that a patch is available for the at least one partition of the software application, downloading the at least one partition from the remote server into volatile memory allocated to the software application on the host computer via the first communications channel, and uploading the at least one partition from the volatile memory allocated to the software application to the smart card.
