Abstract: An aspect of the invention relates to a method for centrally updating inventory of electronic provider objects comprising: merging a plurality of object changes from a first queue by change category; for each change category, determining an impact of the merged object changes on a set of data pairs in a general database, each data pair being formed by two given attributes of an electronic provider object placing each impacted data pair in a second queue; determining, for each impacted data pair, an update of the two given attributes of an electronic provider object over a second predetermined period via a query to the general database.

Abstract: A technique is provided for extending a handshake communication between a communication device and an application server. The application server receives at least two messages from the communication device, each message comprising a handshake index and triggering a handshake session so that the application server negotiates with the communication device a set of cryptographic parameters. For each received message, the application server stores a negotiated set of cryptographic parameters in correspondence with a connection state index depending on the handshake index. The application server activates one of the stored sets of cryptographic parameters to establish a secured connection with the communication device.
