Fig. 2 shows the suitable environment of driver testing method according to an embodiment of the invention, thereby explains the notion of a driver of poor quality not being carried out test; And
Fig. 3 is a process flow diagram, show the driver manufacturing undertaken by the driver manufacturing installation and the driver test processes of being undertaken by proving installation (test procedure) for example.
Embodiment
One embodiment of the present of invention are described below with reference to the accompanying drawings.
Fig. 1 shows the suitable environment of driver testing method according to an embodiment of the invention, thereby explains by a real process and make driver and this real driver is carried out the notion of testing.Fig. 2 shows the suitable environment of driver testing method according to an embodiment of the invention, thereby explains by an illegal process and make driver and this driver of poor quality is not carried out the notion of test.
As shown in fig. 1, driver (as CD drive) 1 comprises one and can rewrite ROM2.When making this driver, driver manufacturing installation 3 is by the rewritten ROM 2 of interface with the peculiar value of driver (the peculiar data of driver) 5 (as sequence numbers) and key data 7 write drivers 1.Rewritten ROM 2 storages of driver 1 depend on the regulated value of hardware, also store peculiar value 5 of driver and the key data 7 that writes.
Driver proving installation 4 (for example people's computing machine) one by one storing test program and predetermined key produce to be handled necessary key data and produces information 6.This test procedure is a unencrypted.It is forbidden sending key data generation information 6 to external unit.Its reason is identical with above-mentioned reason.In other words, produce information 6 by the strict control key data and prevent from illegally to produce key data 7.
Fig. 3 is a process flow diagram, show the driver manufacturing undertaken by driver manufacturing installation 3 and the driver test processes of being undertaken by proving installation 4 (test procedure) for example.
Shown in the process flow diagram of Fig. 3, at first, driver manufacturing installation 3 peculiar value 5 of write driver (as sequence number) and produce by predetermined key and to handle the key data 7 (ST1) that produces according to the peculiar value 5 of driver in driver 1 (can rewrite ROM 2).
When test driver 1, driver proving installation 4 (test procedure) is read peculiar value 5 of driver and key data 7 (ST2) from driver 1.Driver proving installation 4 (test procedure) produces information 6 generation key datas 7 (ST3) according to the key data of peculiar value 5 of driver of reading and storage in advance.Key data 7 that is produced and the key data of reading 7 compare the authenticity (ST4) to confirm this driver.
If the key data that is produced 7 meets ("Yes" among the ST5) with the key data of reading 7, then driver proving installation 4 (test procedure) determines that this driver is real (ST6) and the operation (ST7) of testing this driver.If the key data that is produced 7 does not meet ("No" among the ST5) with the key data of reading 7, then driver proving installation 4 (test procedure) determines that this driver is the operation (ST9) that (corrupt) of poor quality (ST8) and not removes to test this driver.
As shown in Figure 2, not have storage key data 7 by the driver 1# that true manufacture process produces.When driver proving installation 4 (test procedure) when relatively key data 7 is confirmed these driver authenticities, do not have the driver 1# of storage key data 7 to be confirmed as not being the driver that produces by true manufacture process.
Suppose that a driver 1# of poor quality stores false key data 7# and the peculiar value 5# of driver in can rewriteeing ROM 2#.Even in this case,, can determine that also this driver is of poor quality by the relation between check dummy key data 7# and the peculiar value of the driver 5#.In other words, even use key to produce information 6 (producing key data 7##), can not produce the dummy key data 7# that is stored in this driver of poor quality by the peculiar value 5# of driver that is stored in the driver of poor quality.When comparing, driver 1# is confirmed as of poor quality to these two keys (dummy key data 7# and the key data 7## that is produced by the peculiar value 5# of driver).
Traditionally, the driver of the predetermined supplier's order of response is confirmed as true driver, so driver determinator 4 (test procedure) is carried out the test to this driver.In other words, or even driver 1#, also can be tested.This may cause by the test procedure leakage technology.
Yet the driver proving installation 4 (test procedure) that is used to carry out method of testing of the present invention is not tested the driver 1# that is defined as fake and poor products, even the predetermined supplier's order of its response.Driver proving installation 4 (test procedure) is not tested the driver 1# (not having the driver of storage key data 7 or the driver 1# of storage dummy key data 7#) that does not make with true manufacture process, even be like this when it is manufactured into predetermined supplier of response and orders yet.Therefore, can avoid leaking any technology from test procedure.
In this embodiment, be used for realizing that function of the present invention (driver testing program) is recorded in driver proving installation 4 (storage unit 5) in advance.Yet, the invention is not restricted to this.Can download similar function (test procedure) to driver proving installation 4 from network.It is that similarly function (driver testing program) can be stored in the recording medium and be installed in the driver proving installation 4 that the another kind of practice is done.This recording medium can be taked any form, as CD-ROM, as long as its can stored programme and is read by this device.Can realize with OS (operating system) cooperation in this device by installing or download the function that obtains.
To those skilled in the art, other advantage and modification will be easy to expect.So the present invention is not limited to the detail and the representative embodiment that show and describe aspect wider here at it.Therefore, can carry out various modifications and not leave spirit or scope by the universal of the present invention of claims and equivalent thereof definition.
