<p><P>PROBLEM TO BE SOLVED: To provide a storage which can strengthen seurity about data stored in a memory section. <P>SOLUTION: A command reverse disturbance 2 extracts a parameter CLb from an input command inputted by an I/O section 12, read the key information DLb corresponding to this from a memory section 4, and performs a reverse disturbance processing of a command and an address information on the basis of a key information DLb. When disturbance processing of multiple times is given, it is difficult that the input command predicts the key information DLb required for the reverse disturbance processing with a parameter CMb contained in the input command. Moreover, the disturbance processing is given by a data disturbance section 3 also about an output Data. Therefore, it is difficult to analyze the content, even if it observes communication of the I/O section 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
