Abstract
The invention relates to the technical field of optical module encryption and recognition, and in particular relates to an automatically recognizable optical module encryption method. According to the method, the effective information of the optical module is extracted and encrypted via an encryption algorithm, and thereby the application safety and reliability of the optical module are effectively improved, and the switch port types are greatly enriched.
Description
Technical field
The present invention relates to the encryption of optical module and identify technical field, particularly to the optical module encryption method of a kind of automatic identification.
Background technology
Along with the demand of the network bandwidth is increased by people day by day, optical fiber is interconnected at the form of network application and gets more and more.As the core component realizing opto-electronic conversion in optical fiber interconnection process, optical module is but very big at the proportion of field fiber.Especially, understanding tacitly territory in the data, optical module is ubiquitous, and demand is huge.Optical module is really " little build has big effect ".And optical module market is flourish, directly results in a lot of bad manufacturer and produce optical module inferior, thus obtaining juice with cheap price.The use of these optical modules inferior, the risk caused is ubiquitous.Some optical module caloric value inferior is big, and some optical module mistake bags are extremely many, some optical module fluctuations of service, some optical module internal information misregistrations etc..These situations all can affect data delivery efficiency, even can destroy normal device.
In order to solve this predicament, the industry standard of high-speed optical module should be formulated on the one hand, and introduce oversight mechanism in optical module industry；Also need to the optical module using a set of simple and reliable mechanism of upstream device producer design of optical module to identify different quality on the other hand.
At present, for specification optical module industry standard, MSA(industrial quarters alliance) tissue has been directed towards the optical module of different model product and carried out specification.Such as formulate INF-8074I standard for SFP optical module, formulate INF-8077 standard etc. for XFP.And in switch industry, Cisco is so that oneself equipment can only use optical module supporting for CISCO, it is verified by SFP encryption mechanism, it is prevented that illegal SFP uses, thus avoiding the module of non-authentication to use the harm brought.
In hardware and environment, the high/low temperature experiment of necessity, humidity, drench with rain etc. tests the reliability that can detect optical module；In software aspects, encipherment protection measure can improve the safety of optical module.
Existing optical module standard has been defined for, and all of optical module have mechanical interface, electric interfaces and software interface.These optical modules as I2C bus from equipment, its data information memory is in EEPRPOM, and I2C bus is by the data transmission to the implementing reading and writing optical module of EEPROM data.It is referred from this thought, if it is possible to by reading the useful information being stored in EEPROM in optical module, selects to realize using and deactivation operation to optical module by these effective informations, it just can be utilized to screen out the optical module of different brands difference quality.
Summary of the invention
In order to solve problem of the prior art, the invention provides the optical module encryption method of a kind of automatic identification, it is effectively increased the safety and reliability that optical module uses, and is greatly enriched the form of switch ports themselves.
The technical solution adopted in the present invention is as follows:
The optical module encryption method of a kind of automatic identification, comprises the following steps:
A, optical module is inserted in the optical port of switch；
B, use the SDK software of switch, read the version information of optical module by its interface function, and be stored in A0H by AES generation ciphertext herein；
C, in SDK software, the optical module information of the optical module cipher-text information being had verified that by charactor comparison and this encryption, if consistent, this optical module can be used, and otherwise disables optical module.
AES is: convert the effective information needing encryption to binary number, then adds encryption formula and check information before data with afterbody.
The front portion of ciphertext and afterbody load deciphering formula and check information, described deciphering formula and encryption formula inverse function relation each other.
In the method flow of the present invention, the step of most critical is that the effective information to optical module carries out extracting encryption.The present invention proposes a kind of new optical module information AES, and this calculation ratio juris is, it would be desirable to the effective information of encryption converts binary number to, then adds encryption formula (being commonly called as key) and check information (available flag position 0X00) before data with afterbody.Converting useful information to encrypted cipher text by this encryption formula, now the front portion of this encrypted cipher text and afterbody load deciphering formula and check information (available flag position 0X11).Encryption formula conciliates Migong formula inverse function relation each other.
Technical scheme provided by the invention has the benefit that
The effect of check information is in that to judge that this field is effective information or cipher-text information.With regard to this, it is possible to effective information is converted to cipher-text information, enhance information security, improve the availability of port.Finally, it is effectively increased the safety and reliability that optical module uses, is greatly enriched the form of switch ports themselves.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in the embodiment of the present invention, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one
As shown in Figure 1, the optical module encryption method of a kind of automatic identification of the present embodiment, comprise the following steps:
A, optical module is inserted in the optical port of switch；
B, use the SDK software of switch, read the version information of optical module by its interface function, and be stored in A0H by AES generation ciphertext herein；AES is: convert the effective information needing encryption to binary number, then adds encryption formula and check information before data with afterbody.
C, in SDK software, the optical module information of the optical module cipher-text information being had verified that by charactor comparison and this encryption, if consistent, this optical module can be used, and otherwise disables optical module.
In the method flow of the present embodiment, the step of most critical is that the effective information to optical module carries out extracting encryption.
The present embodiment proposes a kind of new optical module information AES, and this calculation ratio juris is, it would be desirable to the effective information of encryption converts binary number to, then adds encryption formula (being commonly called as key) and check information (available flag position 0X00) before data with afterbody.Converting useful information to encrypted cipher text by this encryption formula, now the front portion of this encrypted cipher text and afterbody load deciphering formula and check information (available flag position 0X11).Encryption formula conciliates Migong formula inverse function relation each other.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
