DATA PROCESSING METHOD, ITS PROGRAM AND ITS DEVICE

摘要

A management device (20) outputs key specification data, read from a card, to an SAM unit (9a). The SAM unit (9a) generates degenerate key data using two-way authentication key data specified by the key specification data. The management device (20) and the SAM unit (9a) perform authentication using the degenerate data. When the SAM unit (9a) authenticates the management device (20), the SAM unit (9a) executes a processing associated with one or more sets of two-way authentication key data used for generating the degenerate key data.
