Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Fig. 1 is a schematic flowchart of a control method for a WIFI device according to an embodiment of the present invention.
As shown in fig. 1, the control method of the WIFI device of this embodiment includes:
s11: and reading License corresponding to the WIFI equipment.
If a developer develops the WIFI equipment without generating corresponding License to protect the WIFI equipment, a user of the WIFI equipment can burn the firmware of the WIFI equipment into other equipment, so that the rights and interests of the developer are damaged. Therefore, the developer can use License to grant the user the right to use the WIFI device and maintain the own rights and interests.
In this embodiment, a License verification program is built in the WIFI device. When a user wants to start the WIFI device, the License is required to be sent to a License verification program for authority verification. And the License verification program reads the License input by the user and verifies whether the License is legal or not, and if the License is illegal, the WIFI equipment is refused to be started.
The license is generated by encrypting through a preset encryption algorithm. The preset Encryption Algorithm may include RSA-1024 asymmetric Encryption Algorithm, Advanced Encryption Standard (AES) AES symmetric Encryption Algorithm, Data Encryption Standard (DES) DES symmetric Encryption Algorithm, International Data Encryption Algorithm (IDEA) IDEA Encryption Algorithm, and other reliable Encryption algorithms.
S12: and decrypting the License to acquire the field information of the decrypted License.
The field information may include protocol header field information, authentication type field information, parameter field information, check field information, and the like.
In this embodiment, after the License verification program reads License input by the user, the public key of the RSA key pair is first decrypted to obtain field information of the decrypted License. The field information comprises protocol header field information, authentication type field information, parameter field information and check field information. The Byte (Byte) unit allocated by the field information of License is shown in table 1.
Table 1 byte unit table of field information allocation of License
As shown in table 1, the protocol header field information includes two Byte units, namely Byte0 and Byte1, where Byte0 is used to store the protocol header information of License; byte1 is used to store License version information.
The authentication type field information contains a Byte unit Byte2 for setting the authentication type of License, and the value of the Byte unit is expressed in hexadecimal. Among them, the authentication types can be divided into three types. That is, the value of Byte2 can be set to three values, i.e., 0x00, 0x01, 0x 02. When the value of Byte2 is set to 0x00, it indicates that the authentication type is physical address authentication, and one License corresponds to one physical address, that is, one License corresponds to only one WIFI device; when the value of Byte2 is set to 0x01, it indicates that the authentication type is physical address segment authentication, and one License corresponds to one physical address segment, that is, one License corresponds to all WIFI devices in the address segment; when the value of Byte2 is set to 0x02, it indicates that the authentication type is valid authentication, and one License corresponds to all WIFI devices, but the License is valid only during the valid period.
The parameter field information comprises (N +1) Byte units between Byte units Byte 3-Byte (N +3), wherein the Byte3 is used for setting the length N of the parameter, and N is a positive integer; the next N byte cells are used to set the value of the parameter. The value of N is different according to the authentication type. When the authentication type is physical address authentication, the value of the parameter is a physical address of 6 bytes, and N is set to be 0x 06; when the authentication type is the authentication of the physical address segment, the value of the parameter is two physical addresses, which are 12 bytes in total, and then N is set to be 0x 0C; when the authentication type is the validity authentication, the time period in which the value of the parameter is 4 bytes represents day, month, year, and time zone in order from low byte to high byte, when N is set to 0x 04.
The check field information includes a Byte unit Byte (N +4) for setting a check code whose value is the sum of the values of the previous (N +4) Byte units, negated by 1, to verify the authenticity of the data of the previous (N +4) Byte units.
S13: and acquiring the authentication type corresponding to License according to the authentication type field information.
In this embodiment, after acquiring the decrypted protocol header field information, authentication type field information, parameter field information, and check field information of the License, the License verification program may acquire the authentication type corresponding to the License according to the acquired authentication type field information.
The authentication types comprise physical address authentication, physical address field authentication and validity period authentication.
When the acquired authentication type field information is 0x00, that is, the value of Byte2 in table 1 is 0x00, the authentication type corresponding to the License acquired by the License verification program is physical address authentication; when the acquired authentication type field information is 0x01, the authentication type corresponding to the License acquired by the License verification program is physical address field authentication; and when the acquired authentication type field information is 0x02, the authentication type corresponding to the License acquired by the License verification program is valid period authentication.
S14: and determining whether the License is legal or not according to the authentication type.
In this embodiment, after the License verification program obtains the authentication type corresponding to the License, whether the License is legal or not can be determined according to the authentication type.
Specifically, when the authentication type is physical address authentication, the License verification program acquires a physical address of the WIFI device, and compares the physical address with a physical address set in the parameter field information to determine whether the License is legal. If the physical address set in the parameter field information is consistent with the acquired physical address, determining that the License is legal; and if the physical address set in the parameter field information is inconsistent with the acquired physical address, determining that the License is illegal.
For example, assuming that the authentication type field information of License is 0x00, the length value of the parameter in the parameter field information is 0x06, and the parameter values are 0x00, 0xE0, 0x66, 0xDB, 0xAA, and 0x8C from high byte to low byte. After the License verification program acquires the authentication type field information of the License, the authentication type corresponding to the License can be determined as physical address authentication, and then the physical address of the WIFI equipment is acquired. Assuming that the physical address acquired by the License verification program is 00-E0-66-DB-AA-8C, namely, the fact that the address in the parameter field information of the License is consistent with the physical address of the WIFI equipment is shown, and the License is legal; otherwise, License is illegal.
And when the authentication type is the physical address field authentication, the License verification program acquires the physical address of the WIFI equipment, acquires the physical address range according to the parameter field information of the License, and further determines whether the License is legal or not according to the acquired physical address range. If the physical address of the WIFI equipment is within the physical address range, determining that the License is legal; and if the physical address of the WIFI device is not in the physical address range, determining that the License is illegal.
For example, assuming that the authentication type field information of License is 0x01, the length value of the parameter in the parameter field information is 0x0C, and the parameter values are 0x00, 0xE0, 0x66, 0xEE, 0x00, 0xE0, 0x65, 0x00, 0x00, and 0x01 in sequence from high byte to low byte. After the License verification program acquires the authentication type field information of the License, the authentication type corresponding to the License can be determined as the physical address field authentication, and then the physical address of the WIFI equipment is acquired. According to the parameter field information of the License, the License verification program can determine that the physical address range is 00-E0-65-00-00-01-00-E0-66-EE-EE-EE, and further determine whether the License is legal or not according to the physical address of the WIFI equipment. If the physical address of the WIFI equipment is in the physical address range, for example, the physical address of the WIFI equipment is 00-E0-66-DB-AA-8C and in the range of 00-E0-65-00-00-01-00-E0-66-EE-EE-EE, determining that the License is legal; and if the physical address of the WIFI equipment is not in the physical address range, for example, the physical address of the WIFI equipment is 00-E0-67-00-0A-5D and is not in the range of 00-E0-65-00-00-01-00-E0-66-EE-EE, determining that the License is illegal.
And when the authentication type is the validity authentication, the License verification program needs to acquire the current time, and then whether the License is legal or not is determined according to the current time. And the current time is the time corresponding to the input License.
Specifically, after obtaining the field information of the License, the License verification program may obtain the valid date of the License according to the parameter field information, and then compare the valid date with the obtained current time to determine whether the License is legal. If the current time exceeds the effective date, determining that License is illegal; and if the current time does not exceed the effective date, determining that the License is legal.
For example, assuming that the authentication type field information of License is 0x02, the length value of the parameter in the parameter field information is 0x04, and the parameter values are 0x00, 0x10, 0x0B and 0x1A from high byte to low byte. After the License verification program acquires the authentication type field information of the License, the authentication type corresponding to the License can be determined to be valid authentication, and then the current time is acquired. According to the parameter field information of the License, the License verification program can determine that the valid date of the License is 2016, 11 and 26 days, and then compare the valid date with the current time to determine whether the License is legal. If the current time does not exceed the effective date, for example, the current time is 2016, 10, 21, determining that the License is legal; if the current time has exceeded the expiration date, such as 2016, 12, and 10, then License is determined to be illegal.
It should be noted that, when the authentication type is validity authentication, the high byte field in the parameter field information is used to set time zone information, default to the east eight zone, and default value of 0x00, that is, representing beijing time. The developer of the WIFI device can set the time zone information according to the actual requirement, which is not limited by the present invention.
S15: and if the WIFI equipment is legal, starting the WIFI equipment.
In this embodiment, after the License verification program determines that the License is legal according to the authentication type, the WIFI device is started. And if the License verification program determines that the License is illegal according to the authentication type, refusing to start the WIFI equipment.
Optionally, as shown in fig. 2, after acquiring the decrypted License field information, the method for controlling the WIFI device in this embodiment may further include the following steps:
s16: and carrying out integrity check on the License according to the protocol header field information and the check field information.
As mentioned above, the protocol header field information includes two byte units, which are respectively used to set the protocol header information of License and the version information of License.
In this embodiment, after the License verification program obtains the decrypted License field information, it may be verified whether the License protocol header information and version information are consistent with the protocol header information and version information pre-stored in the WIFI device according to the protocol header field information. If the WIFI equipment is inconsistent with the WIFI equipment, the WIFI equipment is refused to be started; and if so, further verifying whether the License is complete according to the check field information. If the License information is not complete after verification, starting the WIFI equipment is refused; and if the License information is complete, further acquiring the authentication type corresponding to the License according to the authentication type field information.
