摘要
To carry out a transaction between a mobile terminal and a device, a recovery phase of at least one limited-life secret is such that: a software application of the mobile terminal prepares (402) a request for recovery of the secret duration of limited life to be sent to the transaction authorization system; instructing (403) the security element to affix a signature and / or an encryption, using at least one key, to said prepared request; and transmits (407) to the transaction authorization system said signed and / or encrypted request. The transaction authorization system transmits (411) to the software application said secret with limited lifetime, after verification (409), thanks to knowledge of each said first key, that said request is authentic. Then, to perform the transaction, the software application transmits to the equipment said limited-life secret or information derived therefrom, to enable the equipment to validate the transaction with the transaction authorization system. .
