Abstract:
The services of an HTTP or HTTPS server, being implemented by or running on a first electronic device, are offered to a second electronic device by exchanging HTTP messages between the first electronic device and the second electronic device over a communication channel according to the Bearer Independent Protocol. An application running on the second electronic device can use the TCP/IP protocol for exchanging HTTP messages with the server. A gateway is employed on the second electronic device, which manages the communication channel and which performs protocol conversion Bearer Independent Protocol - TCP/IP for messages received from the application running on the second electronic device, and protocol conversion TCP/IP - Bearer Independent Protocol for messages being sent to the server.
Abstract:
Method for monitoring the usage of a service by a communication device coupled to a tamper resistant module, in particular a smart card. A said service is transmitted from a resource able to communicate with said communication device by way of a network. The service comprises a plurality of encrypted data flow and its use comprises successive decryption steps of data flow by a respective first key EK, said first key EK being encrypted in the data flow and decrypted in the tamper resistant module by way of a second key KEK stored in said tamper resistant module or derived inside said module. The invention is characterized in that said method comprises the following steps: a. A counting step, in which a memory location stores a count of occurrences of decryption steps of said first key EK attached to a same service; b. A using step, in which said counter is used to prove the amount of data flow which has been decrypted.
Abstract:
A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network, said data processing device and said remote system adapted to store a plurality of parameters identifying a user account belonging to a subscriber, said data processing device comprising: a one-time parameter comprising the active account attached to said device designed for a one-time use, a permanent parameter identifying an account attached to said data processing device, said permanent parameter being deactivated,wherein said one-time and permanent parameter are stored in said at least one remote system, and said microcontroller is programmed to:c) using the one-time parameter to logon to the network when said data processing device is switched on;d) exchanging the one-time parameter with the permanent parameter, upon successful logon to the network, said permanent parameter becoming the permanent active account, wherein said first device and said at least one remote system store a parameter identifying a current active account attached to a second data processing device to replace, and upon successful logon to the network, a program automatically stored in said first device sends an activation request for exchanging the plurality of parameters from the old for the new one in said at least one remote system, with the current active account being deactivated.
