Abstract: An entity of the smart card type has an application layer linked to a communication protocol layer. A time manager containing a timer interfaces with the protocol layer. The time manager substantially periodically constructs waiting time extension requests transmitted to a terminal through the protocol layer as long as data are being processed in the application layer. The application layer is thus freed from any time constraint.

Abstract: The invention solves the problem of systematic image marking of portable communicating objects, such as smart cards or mobile terminals, involved in a campaign in a database connected to a downloading server, thereby releasing the server. Access to a communicating object targeted by the campaign is authorized for a single-unit operation while the server manages the preprocessing of data for the communicating object during the campaign. Access is inhibited for a single-unit operation concerning an object targeted by the campaign when access is requested while the server manages transmission of a data message to the communicating object during the campaign. Access is also prohibited while the server manages an acknowledgement transmitted by the communicating object and the post-processing of data concerning the communicating object.

Abstract: A system and a method for operating a device that is not capable of independently maintaining a local time clock to enforce a time-based transaction policy that requires a reliable time reference. The device establishes a secure communications channel to one or more network-attached time sources and inquires of each of the network-attached time-sources as to the current time using the secure communications channel. The device receives the current time from the network-attached time-sources and uses the received current times to estimate a current calendar time and to compute a reliability index associated with the estimated current calendar time. The device uses the estimated current calendar time and reliability index to enforce the time-based transaction policy.

Abstract: A system and method for creating a trusted network capable of facilitating secure transactions via an open network using batch credentials, such as batch PKI certificates, is presented. A certificate is bound to a group, or batch, or devices. This certificate is referenced by an activation authority upon processing a request for service by a device. Information regarding the device batch certificate is maintained in a permanent, or escrow, database. A user identity is bound to a device, as a device key is used to sign a user key created on the device in the presence of the user, and a copy of the device key is later used to decrypt the signed user key upon its transmission and receipt.
