摘要：
A method uses portable objects where the reading and writing of data in the memory are free, owing to the writing in the latter, if necessary, of elements which can be prepared and verified only if secret information kept both in a secure memory at the control center and in a secure memory in the machine with which the transmission is carried out is known.
