[Detailed description of the invention]
Fig. 1 is the schematic diagram of TPM test device of the present invention.
Fig. 2 is the operation workflow figure of TPM test method of the present invention.
[specific embodiment]
Refering to Figure 1, TPM test device 100 of the present invention includes memory cell 102, microcontroller 104 and network
Communication unit 106.The microcontroller 104 of TPM test device 100 penetrates spi bus (Serial Peripheral
Interface Bus) it is communicated to connect with trusted platform module 200 (hereinafter referred to as TPM 200), to be tested.Microcontroller
104 are communicated through network communication unit 106 with remote monitoring host 300, for example, in microcontroller 104 to TPM
After 200 tests, microcontroller 104 can pass through network communication unit 106 and transmit the signal for being relevant to test result to distally
Monitoring host computer 300, and remote monitoring host 300 can correspondingly output test result be supplied to scene operator perform an analysis.
In some embodiments, remote monitoring host 300 can be field data monitoring system (SFCS).
In some embodiments, memory cell 102 stores plural number test instruction, and each test instruction corresponds respectively to not
Same TPM version (for example, TPM 1.0, TPM 1.2 and TPM 2.0 etc.), in addition, memory cell 102 also stores each survey
The corresponding normal condition echo message of examination instruction.
In some embodiments, when microcontroller 104 tests TPM 200, microcontroller 104 can first judge
The version of TPM 200, the test that then microcontroller 104 then chooses the version of corresponding TPM 200 from memory cell 102 refer to
It enables, and the test is directly transmitted with the interface SPI and is instructed to TPM 200.
Finally, the normal condition echo message that microcontroller 104 compares the storage of memory cell 102 again is returned with TPM 200
The test echo message of biography, judges whether TPM 200 operates exception whereby.
Specifically, when microcontroller 104 judges the test echo message and memory cell 102 that TPM 200 is returned
Corresponding normal condition echo message is identical, and microcontroller 104 then generates test normal signal, to indicate its test result
It is normal.For example, the test normal signal is sent to remote monitoring host through network communication unit 106 by microcontroller 104
300, and remote monitoring host 300 then accordingly shows proper testing result (for example, single through display according to test normal signal
Member is shown the normal information of TPM or is given a green light using LED and indicated).
On the other hand, when microcontroller 104 judges the test echo message and memory cell 102 that TPM 200 is returned
Corresponding normal condition echo message is not identical, and microcontroller 104 can then generate test according to the abnormal project of test
Abnormal signal, to indicate that its test result is abnormal.For example, microcontroller 104 penetrates network communication unit 106 for the test
Abnormal signal is sent to remote monitoring host 300, and remote monitoring host 300 can then analyze the test abnormal signal and accordingly
Show abnormality test result (for example, showing the information of specific project exception in TPM through display unit or utilizing LED azarin
Lamp indicates).In further embodiments, also display unit or LED light can be set in TPM test device 100 to show test
As a result.
It please refers to shown in Fig. 1 and Fig. 2, TPM test method of the present invention then can be saturating after TPM test device 100 powers on
It crosses spi bus and TPM 200 is communicated to connect, in step S202, the microcontroller 104 of TPM test device 100 detects TPM
200 version.For example, reading instruction to TPM 200 through spi bus transmission version.And when TPM 200 receives version reading
After instruction fetch, then return about itself version information to TPM test device 100 microcontroller 104.
In step S204, microcontroller 104 is chosen according to the version of the TPM 200 judged from memory cell 102
The normal condition echo message of the test instruction of the corresponding version and corresponding test instruction.It will be understood that memory list
The normal condition echo message stored in advance in member 102 is that TPM should be returned when receiving test instruction in normal state
Information.Then in step S206, selected test instruction is sent to TPM 200 through spi bus by microcontroller 104.
And after TPM 200 receives test instruction, then it can be instructed according to test and generate test echo message to be back to TPM test
The microcontroller 104 of device 100.
Then, in step S208, microcontroller 104 then compares the test echo message that TPM 200 is returned and storage
Whether the normal condition echo message stored by device unit 106 is identical.If it is different, then continuing step S210, microcontroller 104 is saturating
The transmission test abnormal signal of network communication unit 106 is crossed to remote monitoring host 300, and continues step S214.Conversely, then continuing
Step S212, the transmission of microcontroller 104 transmission of network communication unit 106 test normal signal to remote monitoring host 300, and after
Continuous step S216.
Finally, remote monitoring host 300 then corresponds to the test that the microcontroller 104 is transmitted to be believed extremely in step S214
Number display abnormality test as a result, with notify scene operator do corresponding disposition.On the other hand, in step S216, distal end
Monitoring host computer 300 then corresponds to the test normal signal that the microcontroller 104 is transmitted and shows proper testing result.
In conclusion TPM test device of the present invention and method, it can be direct by the setting of TPM test device 100 of the present invention
TPM 200 is tested through the interface SPI, without each TPM 200 is set to corresponding clothes one by one respectively respectively
It is engaged on device, not only saves the cost of test fixture, more greatly reduce over the time for having to wait for server booting
And the puzzlement of server firmware cooperation, the efficiency of test trusted platform module (TPM) is increased significantly.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
