Abstract: A smart card compares an object identification parameter associated with a write command with an object identification parameter stored in the non-volatile memory of the smart card. If the comparison is positive, the data embedded in the write command is written at a at a predefined address whose value is stored in the non-volatile memory, an address corresponding to the sum of the stored predefined address and the size of the written data is calculated, and the calculated address is stored in the non-volatile memory in place of the predefined address. If the comparison is negative, the data is written at a default address, an address corresponding to the sum of the default address and the size of the written data is calculated, and the calculated address is stored in the non-volatile memory as the predefined address.

Abstract: The invention relates in particular to a method for writing data in a non-volatile memory of a smart card. The invention also relates to a smart card and a computer program capable of implementing such a method, to a storage medium including such a computer program, and to a system including a smart card and a device making it possible to write in the card.
