Referring to Fig. 1, the application scenarios schematic diagram of data access is realized for the application embodiment of the present invention.As shown in Figure 1, first Bluetooth equipment and the second bluetooth equipment can be mobile phone, computer and ipad etc. with Bluetooth function, and the second bluetooth equipment can With based on the data on the first bluetooth equipment of Bluetooth Low Energy protocol access, i.e., first bluetooth equipment is as server, this Two bluetooth equipments are as client.
In an embodiment of the present invention, for the first bluetooth equipment with the second bluetooth equipment after establishing plaintext and connecting, second is blue Tooth equipment, can be close by providing to the first bluetooth equipment when needing the data of Certificate Authority on accessing the first bluetooth equipment The first verification information is written in code verifying feature field, so that the first bluetooth equipment obtains the first verification information.Later, first is blue Tooth equipment can obtain the first information according to the first password of the second bluetooth equipment of its local current record, and judge this Whether one information is consistent with the first verification information, if unanimously, first verification information of the second bluetooth equipment is notified to be proved to be successful, Allow to access the data for needing Certificate Authority.That is, two bluetooth equipments in the present embodiment are in mutually access data, both sides are first First accessed based on plaintext connection type, then, when access side accesses the data for needing accessed square Certificate Authority access, After operating access side's execution associated verification by accessed side, then decide whether that access side is allowed to access.Aforementioned this access side Formula, both sides increase a secure authentication mechanisms on the basis of plaintext connection type, that is, can reach indigo plant without establishing encrypted link The good compatibility of tooth equipment and the higher effect of safety for accessing data.
It referring to fig. 2, is one embodiment flow chart of data access method of the present invention, this method can be applied to include the In the system of one bluetooth equipment and the second bluetooth equipment, when first bluetooth equipment is as server, which makees When for client, which is described from the first bluetooth equipment side, may comprise steps of:
Step 201 after connecting in plain text with the foundation of the second bluetooth equipment, receives the second bluetooth equipment and sets in the first bluetooth of access The first verification information for needing to be written when the data of Certificate Authority into the password authentification feature field of the first bluetooth equipment on standby.
In the present embodiment, since two bluetooth equipments of Bluetooth Low Energy protocol communication are typically based on GATT (Generic Attribute Profile, general-purpose attribute configuration) realize data interaction, the basic structure in the GATT for storing data is Feature, each feature include operational attribute, data and UUID (Universally Unique Identifier, it is general unique Identification code) etc. fields, and the operational attribute in feature determine user to data in this feature can be performed operation, it is such as right Data in this feature are readable, writeable, read-write and can not read and write.Thus, when the first bluetooth equipment is as server, When two bluetooth equipments are as client, for may be coupled to the second bluetooth equipment of each of first bluetooth equipment, first is blue Tooth equipment and second bluetooth equipment can be consulted before Certificate Authority in advance, and second bluetooth equipment is to the first bluetooth equipment The operational attribute of upper each feature, and after Certificate Authority, second bluetooth equipment is to each feature on the first bluetooth equipment Operational attribute.
When the second bluetooth equipment needs to access the data on the first bluetooth equipment, the second bluetooth equipment can be first with One bluetooth equipment is established to be connected in plain text, then sends request of data message to the first bluetooth equipment, can in the request of data message It is set with the address information (MAC Address etc.), the address information of the first bluetooth equipment, the second bluetooth that include the second bluetooth equipment The behaviour that the data in feature that the UUID and the second bluetooth equipment of the standby feature requested access to request access to it will execute Make etc..First bluetooth equipment, can be first according to the second bluetooth in request of data message after receiving the request of data message The UUID for the feature that the address information of equipment and the second bluetooth equipment request access to, determining before Certificate Authority, second indigo plant Operational attribute of the feature of tooth device request access on the first bluetooth equipment judges the second indigo plant then according to the operational attribute Whether the operation that the data in feature that tooth equipment requests access to it will execute is legal, if legal, then it represents that the second bluetooth The data of device request access, which do not need Certificate Authority, may have access to, if it is illegal, then it represents that the second bluetooth equipment requests access to Data need Certificate Authority after just may have access to, at this time the first bluetooth equipment can to the second bluetooth equipment returned data request lose Lose message.
In the present embodiment, it is only that writeable password is tested that the first bluetooth equipment, which can provide operational attribute to the second bluetooth equipment, Characteristics of syndrome field.After needing Certificate Authority on the second bluetooth equipment the first bluetooth equipment of access when just addressable data, the The first verification information is written in the password authentification feature field that two bluetooth equipments can be provided to the first bluetooth equipment.In order to guarantee The safety of first verification information transmission, first verification information can be calculated for the second bluetooth equipment according to preset first encryption Method, using user input first verifying password to the first bluetooth equipment and the second bluetooth equipment both sides negotiation certificate parameter into After row encryption, the information of generation.Wherein, which can be built in the first bluetooth equipment and the second bluetooth to be prior Algorithm in equipment.
However, since Encryption Algorithm can be divided into irreversible cryptographic algorithm and irreversible encryption algorithm, and reversible encryption is calculated Method usually has two reversible processes of encryption and decryption, if according to irreversible cryptographic algorithm, using the first verifying of user's input The certificate parameter that password negotiates the first bluetooth equipment with the second bluetooth equipment both sides is encrypted, then first generated is tested Information is demonstrate,proved during password authentification feature field is written, once being trapped, is just easy to parse the first verifying password, from And password is caused to be revealed.Thus, in order to further increase the safety of the first verification information write-in, which can be with For irreversible encryption algorithm, such as MD5 (Message Digest Algorithm 5, Message Digest Algorithm 5) algorithm or SHA1 (Secure Hash Algorithm, Secure Hash Algorithm) algorithm etc..
In addition, the certificate parameter can be using challenge word string.Verifying password is attacked in order to prevent, and challenging can be in word string Character including variation.For example, challenge word string can be " first the+the second bluetooth equipment of bluetooth equipment MAC Address MAC Address+company Connect the first bluetooth equipment time when channel number when establishing+this connection AccessCode+ connection is established ", wherein challenging Latter two character " the Access Code of this connection " and " the first bluetooth equipment time when connection is established " are second in word string Bluetooth equipment is all different when establishing data connection every time with the first bluetooth equipment.Due in the second bluetooth equipment and the first bluetooth Equipment is established the challenge word string used when data connection every time and is all different, therefore may further ensure that verifying password transmission Safety.
Step 202, the first password according to second bluetooth equipment of local current record, obtain the first information.
In the present embodiment, when second bluetooth equipment be written into the password authentification feature field of the first bluetooth equipment When one verification information is the first verifying password that user inputs to the second bluetooth equipment, accordingly, which is first blue First password of the tooth equipment in the second bluetooth equipment of local current record.When second bluetooth equipment is to the first bluetooth equipment The first verification information being written in password authentification feature field is that the second bluetooth equipment uses first Encryption Algorithm, using user After first verifying password of input encrypts the certificate parameter, when the information of generation, accordingly, which is first For bluetooth equipment according to first Encryption Algorithm, the first password using the second bluetooth equipment of local current record joins the verifying After number is encrypted, the information of generation.
Whether step 203, to judge the first information consistent with the first verification information, if unanimously, notifying the second bluetooth equipment First verification information is proved to be successful, and allows to access the data.
In the present embodiment, the first bluetooth equipment is in addition to that can provide password authentification feature field to each second bluetooth equipment Outside, password can also being provided to each second bluetooth equipment and modifying feature field, which modifies the first of the operational attribute of feature Initial value is not writeable.After the first bluetooth equipment judges that the first information is consistent with the first verification information, the first bluetooth equipment is not It can only notify second the first verification information of bluetooth equipment to be proved to be successful, allow to access the data, but also can be by the first indigo plant The operational attribute for the password modification feature field that tooth equipment is provided to second bluetooth equipment is revised as writeable.At this point, second is blue Tooth equipment can modify feature field based on the password, the first verifying password (i.e. first used when accessing the data it Password) it modifies.
Specifically, the first bluetooth equipment is when judging that the first information is consistent with the first verification information, can determine this One verifying password is identical as first password, and hereafter, the second bluetooth equipment can be first to the first indigo plant when modifying the first password Password modification information is written in the password modification feature field that tooth equipment provides, which can set for the second bluetooth Standby the second Encryption Algorithm negotiated according to the first bluetooth equipment and the second bluetooth equipment both sides, (i.e. using the first verifying password First password before modification) to user input new password be encrypted after, the information of generation.First bluetooth equipment is connecing After receiving password modification information, can according to decipherment algorithm corresponding with second Encryption Algorithm, to the password modification information into Row decryption, if successful decryption, obtains the new password, notifies second bluetooth equipment to be properly received the new password, and incite somebody to action this Second password of the second bluetooth equipment of ground current record replaces with the new password.The present embodiment by user is inputted it is new Password is written before password modification feature field, according to the second Encryption Algorithm, is inputted using the first password before modification to user New password be encrypted, can be improved new password transmission safety.It is to be noted that due to the first bluetooth equipment It needs that the password modification information is decrypted after receiving password modification information, thus second Encryption Algorithm can be for can Reverse encryption algorithm.
When the second bluetooth equipment, which receives the first bluetooth equipment, has been properly received the notice of the new password, can press first According to first Encryption Algorithm, the certificate parameter is encrypted using the new password that user inputs, generates the second verification information, so Second verification information is written in the password authentification feature field that the first bluetooth equipment provides afterwards.First bluetooth equipment is receiving To after second verification information, it can judge that the first information and second verification information are inconsistent first, this is second close When code is not initial value, according to first Encryption Algorithm, the certificate parameter is encrypted using second password, is obtained Second information；Then when judging that second information is consistent with second verification information, which is replaced with second Password, and initial value is set by the second password, notify the second bluetooth equipment first password successfully modified.
In addition, the second bluetooth equipment is set to the first bluetooth in the first bluetooth equipment and the second bluetooth equipment interactive process Its notice for being properly received the new password that the new password and the first bluetooth equipment that preparation is sent are returned to the second bluetooth equipment is all The case where being likely to occur packet loss.It, certainly will not be to the second bluetooth equipment when the first bluetooth equipment is not successfully received new password Its notice for being properly received the new password is returned, therefore is successfully connect when the second bluetooth equipment does not receive the first bluetooth equipment When receiving the notice of new password, the second bluetooth equipment can determine first password modification failure.
When first password modifies failure, if the second bluetooth equipment accesses after needing Certificate Authority on the first bluetooth equipment Just addressable data, then the second bluetooth equipment can be write into the password authentification feature field of the first bluetooth equipment offer first Enter first verification information, later, the first bluetooth equipment can be when judging that the first information is consistent with the first verification information, will Second password is set as initial value, and the second bluetooth equipment first verification information is notified to be proved to be successful, and allows to access the number According to；Judging that the first information and the first verification information are inconsistent, and second password be initial value when, notify the second bluetooth Equipment the first verification information authentication failed, does not allow to access the data；Judging the first information and the first verification information Inconsistent, which is not initial value, and second information and the first verification information it is inconsistent when, notify the second bluetooth to set The standby first verification information authentication failed, does not allow to access the data；And judging the first information and the first verification information Inconsistent, the second password is not initial value, and when the second information is consistent with the first verification information, notifies the second bluetooth equipment first Verification information is proved to be successful, and allows to access the data.
After the first verification information is proved to be successful, the first bluetooth equipment can be according to scheduled rules modification second bluetooth Equipment on the first bluetooth equipment after Certificate Authority the just operational attribute of addressable feature.It verifies and loses when the first verification information After losing, the second bluetooth equipment can continue the first verifying of write-in letter into the password authentification feature field that the first bluetooth equipment provides Breath, hereafter, the first bluetooth equipment can in the above way verify first verification information, and to the number of verifying into Row statistics.When verifying number more than given threshold, the first bluetooth equipment can actively disconnect the company with second bluetooth equipment It connects, and second bluetooth equipment is included in dynamic blacklist, it is possible thereby to further increase the safety of data access.
The present embodiment is failed by modifying in first password, and the second bluetooth equipment accesses to be needed to authenticate on the first bluetooth equipment After authorization when the addressable data of, the first bluetooth equipment is using the first information and the second information successively to first verification information It is verified, when the first verification information is consistent with any one information in the first information and the second information, that is, when user inputs First verifying password and the first bluetooth equipment any one password in the first password and the second password of local current record When identical, so that it may determine that first verification information is proved to be successful, it is possible thereby to avoid user to be proved to be successful, input is modified Preceding first password and modified first password the two passwords are verified, so as to improve verification efficiency.In addition, this Embodiment is by judging that the first information and the first verification information are inconsistent in the first bluetooth equipment, and the second password is initial When value, determine the first verification information authentication failed, can to avoid execute judge the second information whether with the first verification information Step, it is possible thereby to further increase the efficiency of verifying.
In addition, the present embodiment is by when the first bluetooth equipment judges that the first information is consistent with the first verification information, Initial value is set by second password, it is ensured that when verifying next time, the first bluetooth equipment is only needed using the first information First verification information is verified, so as to further increase the efficiency of verifying.Similarly, the present embodiment passes through One bluetooth equipment judges that the first information and the first verification information are inconsistent, and the second password is not the initial value, and second believes When ceasing consistent with the first verification information, after the second password is substituted for first password, initial value is set by second password, Can guaranteeing, the first bluetooth equipment only needs the first verification information to be verified using the first information when verifying next time, from And it can be further improved the efficiency of verifying.
It is another embodiment flow chart of data access method of the present invention referring to Fig. 3, this method is applied to include first In the system of bluetooth equipment and the second bluetooth equipment, when the first bluetooth equipment is as server, the second bluetooth equipment is as client When end, which is described from the second bluetooth equipment side, may comprise steps of:
