Fig. 1 is a schematic block diagram of a structure of an electronic device 10 to which a counterfeit optical module detection method and a counterfeit optical module detection apparatus 100 according to an embodiment of the present invention are applied, and referring to fig. 1, the counterfeit optical module detection method and the counterfeit optical module detection apparatus 100 according to the embodiment are applied to the electronic device 10. The electronic device 10 may be a communication device, a server or a storage device, etc. The electronic device 10 is used for plugging the first optical module and the second optical module. The electronic device 10 includes a body (not shown), a memory 11, a processor 12, and a counterfeit light module detecting apparatus 100. A first port and a second port are arranged on the machine body, the first optical module is connected to the first port in an inserting mode, and the second optical module is connected to the second port in an inserting mode.
The memory 11 and the processor 12 are electrically connected to each other directly or indirectly to enable data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The counterfeit light module detection apparatus 100 includes at least one software function module which may be stored in the memory 11 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of a server. The processor 12 is configured to execute executable modules stored in the memory 11, such as software functional modules and computer programs included in the counterfeit light module detecting device 100.
The Memory 11 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (eeprom), and the like. The memory 11 is used for storing a program, and the processor 12 executes the program after receiving an execution instruction.
Referring to fig. 2, the method for detecting a counterfeit optical module according to the present embodiment includes the following steps:
step S100 reads first encryption information of the first optical module and second encryption information of the second optical module.
In this embodiment, the first optical module and the second optical module are respectively inserted into the recording device, and the encryption software written in the pluggable optical module is run. The encryption software respectively reads the identity information of the first optical module and the identity information of the second optical module as encryption input, wherein the identity information is information for uniquely identifying the optical module, such as a serial number and the like. The encryption software carries out encryption calculation on the identity of the first optical module through an encryption algorithm to obtain first encryption information, and the encryption software carries out encryption calculation on the identity of the second optical module through the encryption algorithm to obtain second encryption information. It is to be understood that the first cryptographic information is unique for the first optical module and the second cryptographic information is unique for the second optical module. The Encryption algorithm may be Advanced Encryption Standard (AES) algorithm, or the like. And writing the first encryption information into an internal user-writable register of the first optical module, and writing the second encryption information into an internal user-writable register of the second optical module. Thus, when the first optical module is inserted into the first port of the machine body, the first encrypted information can be read, and when the second optical module is inserted into the second port of the machine body, the second encrypted information can be read.
It should be noted that, the existing optical module encryption scheme is easily imitated by a malicious user. The entire contents of registers in the optical modules, including the encryption information, can be easily copied for mass production of counterfeit optical modules. The counterfeit optical modules are inserted into different ports of the electronic equipment in batches, and because the identity verification of the single optical module is realized only through the identity identification of the single optical module, the counterfeit optical modules cannot be identified in batches, so that the counterfeit optical modules can be normally used on the electronic equipment. Once a problem occurs, the optical module is considered by the user as an optical module of the electronic device manufacturer, thereby causing a huge loss to the electronic device manufacturer. The counterfeit optical module detection method, the counterfeit optical module detection device and the electronic device provided by the embodiment further avoid the use of counterfeit optical modules through comparison of encrypted information among a plurality of optical modules, can identify counterfeit optical modules which are copied in batches through copying register contents, and can effectively protect the benefits of manufacturers of electronic devices.
Step S200, comparing whether the first encryption information and the second encryption information are the same.
In this embodiment, the first encryption information and the second encryption information are compared to determine whether they are the same. Since the first cryptographic information is unique to the first optical module and the second cryptographic information is unique to the second optical module, if the first cryptographic information and the second cryptographic information are the same, the first optical module and the second optical module can be considered as counterfeit optical modules that are mass-counterfeited by copying contents of registers in the optical modules. If the first encryption information and the second encryption information are not the same, the first optical module and the second optical module can be considered not to be fake optical modules which are copied in batch by copying the register content in the optical modules, and the first optical module and the second optical module can work normally.
When the first encryption information and the second encryption information are the same, step S300 is performed. Step S300 includes performing exception handling on the optical module.
In this embodiment, when the first encryption information and the second encryption information are the same, exception handling is performed on the first optical module and the second optical module. And when the first encryption information and the second encryption information are the same, judging that the first optical module and the second optical module are fake optical modules which are copied in batches by copying the content of a register in the optical modules, and performing exception handling on the first optical module and the second optical module. The exception handling may be to cause the first optical module and the second optical module to fail to operate normally, and to send out an alarm signal.
In this way, it is possible to identify counterfeit optical modules that are copied in bulk by copying the register contents, and the benefits of the manufacturer of the electronic device 10 can be effectively protected.
It should be noted that, when the first encryption information and the second encryption information are not the same, step S500 is executed. Step S500 includes operating the optical module normally.
Further, in this embodiment, before step S200, the first optical module and the second optical module may also be respectively authenticated. In this embodiment, the purpose of performing identity authentication on the first optical module and the second optical module respectively is to determine whether the first optical module and the second optical module are optical modules sold by preset manufacturers. When the first optical module and the second optical module pass the authentication, step S200 is executed.
In this embodiment, when the first optical module and the second optical module fail to pass the authentication, step S300 is executed.
Referring to fig. 3, in this embodiment, the respectively performing identity verification on the first optical module and the second optical module may include:
step S411, reading the identity information of the first optical module and the second optical module.
In this embodiment, the identity information of the first optical module is information that can uniquely identify the first optical module, such as a serial number. It should be noted that step S411 may be performed simultaneously with step S100, that is, when the first encryption information of the first optical module is read, the identity information of the first optical module may be read simultaneously. In this embodiment, the identity information of the second optical module is information that can uniquely identify the second optical module, such as a serial number. It should be noted that step S411 may be performed simultaneously with step S100, that is, when reading the second encryption information of the second optical module, the identity information of the second optical module may be read simultaneously.
Step S412, obtaining third encryption information according to the identity information of the first optical module.
In this embodiment, in step S412, the identity information of the first optical module is encrypted to obtain third encrypted information. The encryption algorithm used for the encryption calculation may be an AES algorithm or the like.
In step S413, it is compared whether the first encryption information and the third encryption information are the same.
In this embodiment, the first encryption information is compared with the third encryption information, and if the first encryption information is the same as the third encryption information, the first optical module is considered to be an optical module sold by a preset manufacturer.
And if the first encryption information is not the same as the third encryption information, the first optical module is not a preset optical module sold by a manufacturer. In this embodiment, when the first encryption information is different from the third encryption information, step S300 is executed to perform exception handling on the first optical module.
Step S421, obtain fourth encryption information according to the identity information of the second optical module.
In this embodiment, in step S421, the identity information of the second optical module is encrypted to obtain fourth encrypted information. The encryption algorithm used for the encryption calculation may be an AES algorithm or the like.
Step S422, it is compared whether the second encryption information is the same as the fourth encryption information.
In this embodiment, the second encryption information is compared with the fourth encryption information, and if the second encryption information is the same as the fourth encryption information, the second optical module is considered to be an optical module sold by a preset manufacturer.
And if the second encryption information is not the same as the fourth encryption information, the second optical module is not a preset optical module sold by a manufacturer. In this embodiment, when the second encryption information is different from the fourth encryption information, step S300 is executed to perform exception handling on the second optical module.
In addition, it should be noted that, when the first encryption information is the same as the third encryption information and the second encryption information is the same as the fourth encryption information, step S200 is executed.
It should be noted that, when detecting optical modules in batch, only the steps of the above method need to be repeatedly executed.
In summary, the counterfeit optical module detection method according to this embodiment compares whether first encryption information of the first optical module and second encryption information of the second optical module are the same, and when the first encryption information is the same as the second encryption information, the first optical module and the second optical module are counterfeit modules that are mass-copied by copying contents of registers on the optical modules, and the first optical module and the second optical module are exception-processed because the first encryption information is unique information for the first optical module and the second encryption information is unique information for the second optical module. Therefore, by comparing the encrypted information among the plurality of optical modules, the use of counterfeit optical modules is further avoided, counterfeit optical modules which are copied in batches by copying the content of the register can be identified, and the benefits of electronic equipment manufacturers can be effectively protected.
