A shutter apparatus includes a blade member, a blade moving member, a locking member, a cam member, and a restriction member. The cam member moves the locking member from the locking position to the non-locking position so that the blade moving member moves from the closing position to the opening position. The restriction member moves from the non-restriction position to the restriction position after the blade moving member moves from the closing position to the opening position. The cam member moves the locking member in a direction opposite to a direction from the non-locking position to the locking position so that the locking member moves the restriction member from the restriction position to the non-restriction position.

If a print misregistration amount on a sheet is larger than a predetermined threshold before determining whether a printed image is appropriate or not, an abnormal status of the image printed on the sheet is detected without correcting image data for inspection. A control method for controlling a detecting apparatus for inspecting a print status of an image printed on a sheet by a printing apparatus includes detecting, in a case where it is determined that a print misregistration amount of the image printed on the sheet with respect to the sheet is larger than a predetermined threshold, an abnormality of the print status of the image read by a reading unit without performing correction.

The encryption device includes a random number generator for generating a random number; and a first selector for selecting one of q fixed values in response to the random number, a second selector for selecting one set of q sets of fixed S-box tables in response to the random number. An XOR XORs an input with an XOR of a key with the fixed value. A nonlinear transform transforms an input nonlinearly in accordance with the selected set of fixed S-box tables. Another encryption device includes a plurality of encrypting units coupled in parallel, and a selector for selecting one of the plurality of encrypting units in response to the random number. The masking with the fixed values improves the processing speed and reduces the required RAM area.

Encryption secured against DPA

Intermediate data a, b, c, and dare prepared by an intermediate data preparing equipmentfrom a cryptographic key through a nonlinear type function operation and the like, an extended key preparing equipmentselects a [X], b [Y], c [Z], and d [W] corresponding to the number of stages r from the intermediate data, and rearranges the data as well as conducts that of bit operation to prepare extended keys, whereby an extended key preparing apparatus by which an extended key required in the case where common key cryptosystem is applied can be safely prepared at a high speed, a process for preparing such an extended key, and a recording medium used therefor are provided.
