INFORMATION PROCESSING DEVICE

摘要

An information processing device of the invention has a first board on which a tamper detection pattern is installed, a second board that is arranged to face the first board and on which a tamper detection pattern is installed, and sidewalls that are arranged between the first and second boards and along the outer periphery of the first and second boards and that include a plurality of layers (41 and 43) upon which electrodes (33 and 34) for tamper detection are provided. A circuit that needs to be tamper proof is provided in the space that is enclosed by the first and second boards and the sidewalls. The sidewalls have a structure in which electrodes (34) in one layer (43) of the two layers (41 and 43) that are adjacent with an insulating layer (42) interposed there between are arranged at positions corresponding to the spaces between the electrodes provided in the other layer (41).

1. An information processing device comprising:
a first board on which a tamper detection pattern is installed; a second board on which a tamper detection pattern is installed and that is arranged to face said first board; and sidewalls that are arranged between said first and second boards along outer peripheries of said first and second boards and that include a plurality of layers in which electrodes for tamper detection are provided; wherein a circuit that needs to be tamper proof is provided in a space enclosed by said first and second boards and said sidewalls; and said sidewalls are configured to include an anisotropic conductive rubber connecter which comprises a construction in which electrodes of an anisotropic conductive rubber which is provided in one layer of two layers that are adjacent to each other, with an insulating layer interposed there between, are arranged at positions corresponding to spaces between electrodes of an anisotropic conductive rubber which is provided in the other layer, and said sidewalls not only protect said circuit that needs to be tamper proof but also electrically connect said tamper detection pattern, which is installed on said second board, to said first board.
