Process for carrying out a transaction between a payment module and a security module

摘要

This invention relates to a process for carrying out a transaction between a payment module and a security module connected to a user's unit, this process being characterized in that it comprises the following steps: entering an identifier representative of the transaction to be carried out by means of an input device; generating by the user's unit, a control message containing at least a representative code of said transaction and an identifier of the security module requiring the transaction; sending said control message to said payment module (PP); verifying in said payment module whether it is entitled to carry out the desired transaction; if the payment module is entitled to carry out this transaction, execution of the transaction, storage of the result of the transaction in said payment module and generation by the payment module, of a receipt relating to the desired transaction and to the related security module; sending said receipt to a management center; sending an unlocking code to the security module (SC) by the management center; registering the transaction in said security module.

1. A process for carrying out a transaction, said process comprising:
receiving, by a hardware decoder, an indication that a transaction to be carried out between a payment module connected to the hardware decoder and a security module connected to the hardware decoder has been requested, said indication including a transaction identifier, the security module being configured to perform conditional access operations; generating by the hardware decoder a control message containing at least a representative code representing said transaction and an identifier of the security module; sending said control message to said payment module; verifying in said payment module whether the payment module is entitled to carry out the transaction; executing the transaction by the payment module, storing a result of the transaction in said payment module, and generating by the payment module a receipt relating to the transaction and to the security module; sending by the hardware decoder said receipt to a management center; receiving an unlocking code at the security module from the management center, said unlocking code being based on the receipt; and registering the transaction in said security module.
