The method of controlling storage logic partition access authority includes the following steps: 1. setting storage access authority controlling area in the storage and setting the access authority of the logic partitions therewith; 2. judging the current chip operation state based on the value in the storage access authority controlling area to complete the access authority control of different logic partitions; and 3. re-writing the value in the storage access authority controlling area to altering the access authority of different logic partitions if necessary and after passing through the cipher verification. The present invention also provides one kind of IC card with function of controlling the access authority of the logic partitions in the storage.
