    摘要: According to an embodiment, a computer program product includes a computer-readable medium including program, when executed by a computer, to have a plurality of modules run by the computer. The computer includes a memory having a shared area, which is an area accessible to only those modules which run cooperatively and storing therein execution module identifiers. Each of the modules includes a first operation configured to store, just prior to a switchover of operations to an other module that runs cooperatively, an identifier of the other module as the execution module identifier in the shared area; and a second operation configured to execute, when the execution module identifier stored in the shared area matches with an identifier of own module immediately after a switchover of operations from the other module, a function inside the own module.

    摘要: According to an embodiment, a memory management device increments a lower value of a first counter, updates the counter by incrementing an upper value and resetting the lower value when the lower value overflows, increments to update the lower counter value when the upper value is incremented as a result of writing a second data piece having the upper value in common to a memory, recalculates a first secret value calculated using the first counter values and a root secret value in response to the first counter update, writes a first data piece and the first secret value to the memory, and at reading of the first data piece and the first secret value, calculates a second secret value using the updated first counter values and the root secret value, and compares the first secret value with the second secret value to verify the first data piece.
