Abstract: The invention relates to a method for authenticating a user. A server accesses an identifier relating to the user associated with an identifier relating to a second user device. The server accesses, for the user, at least one predetermined reference location within a reference table. The method comprises the following steps. Sending from a first user device to the server, through a first communication channel, a first message including the identifier relating to the user and a request to get a challenge table, as challenge user authentication data. Generating, by the server, a first challenge table including a first set of characters, the first challenge table being valid. Sending, thanks to the second user device identifier, from the server to the second user device, through a second communication channel, a second message including the first challenge table and a first request to display the first challenge table. Displaying, by or through the second user device, the first challenge table.

Abstract: A method for authenticating a user includes connecting to a server from a user device, loading from the server to the user device data including executable data, detecting by the user device, while executing the executable data, whether an identifier relating to a short range communication device exists in a vicinity of the user device, sending from the user device to the server a user identifier accompanied with the detected short range communication device identifier, verifying by the server for the identified user whether a detected short range communication device identifier matches a predetermined part of a reference short range communication device identifier. Access is granted from the server only if the detected short range communication device identifier matches the predetermined part of the reference short range communication device identifier.

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: 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: 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: A system and method to control a device having at least one configurable parameter. Enumerating the device as a first peripheral device and as a second peripheral device wherein the first peripheral device corresponds to a first microcontroller connected to a storage medium and the second peripheral device corresponds to a second microcontroller. Controlling the at least one configurable parameter of the first microcontroller with respect to the storage medium by the second microcontroller. On initialization of the device, transmitting the at least one configurable parameter from the second microcontroller to the first microcontroller. Other systems and methods are disclosed.

Abstract: A mobile device and UICC communication using standard Internet protocols. Such communication allows users access to their UICC information using standard web browsers and allows use of the UICCs to communicate with remote servers and thereby provide secure services for Internet transactions. The mobile device has a communications module to selectively communicate with the UICC processor or with at least one node on a network, the mobile device communications module has an Internet protocol module operable to receive messages issued from a first Internet application as Internet protocol packets, and to transmit the packets to target IP addresses; and operable to receive Internet protocol packets, to process the packets, and to send the messages contained in the packets to the first Internet application.
