| 摘要 |
<p>The present invention relates to a synchronization method (MTH) for synchronizing a peripheral function (PF) of a portable device (D), said peripheral function (PF) using first data (DAT1), said portable device (D) comprising a component (MC) adapted to perform said peripheral function (PF) and a secure element (SE) adapted to perform a main function (MF). Said synchronization method (MTH) comprises a synchronization of said first data (DAT1) with reference data (DAT2) via a communication link (LNK1) established for said main function (MF) between said portable device (D) and a remote server (SERV1), said synchronization comprising:
- the transmission by said secure element (SE) of a first message (Msg1) to said remote server (SERV1) via said communication link (LNK1);
- the reception by said secure element (SE) of a second message (Msg2) from said remote server (SERV1) via said communication link (LNK1);
- the checking by said secure element (SE) if said first data (DAT1) are shifted with respect to said reference data (DAT2) according to said second message (Msg2).</p> |
