Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
In some scenarios of smart device communication interaction, dynamic encryption instructions are required for security control. As can be seen from the principle of random number generation, the latter random number has nothing to do with the former random number, and thus the random number provides a dynamic factor. And converting a random number into a plurality of instructions, and controlling each intelligent device by using different instructions to enable each intelligent device to complete an interaction process.
Example one
Fig. 1 is a flowchart of an instruction determining method according to an embodiment of the present invention, where this embodiment is applicable to a case where multiple instructions need to be determined according to a random number, and the method may be executed by an instruction determining apparatus according to an embodiment of the present invention, where the apparatus may be implemented in a software and/or hardware manner. Referring to fig. 1, the method may specifically include the following steps:
s110, encrypting the random number provided by the local equipment by applying the set encryption algorithm to determine encrypted data.
In practical applications, the local device provides a dynamic random number, and the local device is an intelligent washing machine, for example, the intelligent washing machine dynamically displays the random number, and updates the random number every 1 minute, for example. And encrypting the currently displayed random number by applying a set encryption algorithm, and determining the encrypted data as encrypted data. The set Encryption Algorithm may be an MD5(Message-Digest Algorithm 5) Algorithm or a des (data Encryption standard) Algorithm, or the like. The encrypted data is obtained by encrypting according to a set encryption algorithm, and the data form, the data characteristics and the like of the encrypted data are related to the specific encryption algorithm used.
Optionally, the encryption algorithm set by the application is an AES encryption algorithm. The AES (advanced Encryption standard) Encryption algorithm is an advanced Encryption standard in cryptography, and is also called Rijndael Encryption method, and the AES Encryption algorithm itself has a complementary code mechanism, so that the Encryption process in the instruction determination method in the embodiment of the present invention has the first byte expansion by applying the algorithm, and the byte expansion reduces the data repetition rate. The data encrypted by applying the AES encryption algorithm to the random number is typically 16 bytes of data.
And S120, converting each byte of the encrypted data into a corresponding decimal number.
Specifically, the encrypted data is converted, and each byte of the encrypted data is converted into a decimal number. In a specific example, after the AES encryption algorithm is applied to encrypt the random number currently displayed by the local device, 16 bytes of encrypted data are obtained, where the encrypted data is not visible to the user, but exists in an encrypted form. If the encrypted data is hexadecimal data, each byte is converted into a corresponding decimal number, for example, the first byte is 0X02, the corresponding decimal number is 2, and the second byte is 0X0A, the corresponding decimal number is 10.
And S130, splicing the decimal numbers to determine a target character string.
Splicing each byte in the encrypted data into the corresponding decimal number, optionally, splicing according to the byte order, that is, splicing the decimal number converted from the second byte after the decimal number converted from the first byte, splicing the decimal number converted from the third byte after the decimal number converted from the second byte … …, and splicing the decimal number converted from the (N + 1) th byte after the decimal number converted from the nth byte, wherein N is a positive integer and represents the byte order. In one specific example, the result of splicing the multiple decimal numbers is a target string, for example, 308255911243902180373566.
S140, splitting the target character string to determine a sub-target character string.
Illustratively, the target character string is split, and one target character string is split into a plurality of sub-target character strings. For example, every other decimal number is selected, every third decimal number is taken as a sub-target string, and if the target string is 308255911243902180373566, the sub-target strings are 385, 025, 914 and 123 … ….
S150, determining the corresponding relation between the sub-target character strings and the local equipment control command.
Specifically, the corresponding relationship between each sub-target character string and the local equipment control instruction is determined, and optionally, the local control instruction comprises quick washing, standard washing, powerful washing, draining or spin-drying and the like. For example, 385 means spin, 025 means fast wash, 123 means power wash, 914 means standard wash, etc. By selecting the sub-target character string corresponding to the local device control instruction, the local device control instruction can be applied to control the local device.
In the embodiment of the invention, a set encryption algorithm is applied to encrypt the random number provided by the local equipment to determine encrypted data; converting each byte of the encrypted data to a corresponding decimal number; splicing the decimal numbers to determine a target character string; splitting the target character string to determine sub-target character strings; and determining the corresponding relation between the sub-target character strings and the local equipment control instructions. The method and the device have the advantages that the secondary encryption of the data encrypted by the random number is realized, the encrypted data is more complicated, the repetition rate is low when the command is determined according to the encrypted data, and the encryption performance is good.
On the basis of the above technical solution, after converting each byte of the encrypted data into a corresponding decimal number, the method further includes: and processing the decimal number according to a set rule after determining that the decimal number is a single digit, wherein the set rule is that a set number is added before or after the decimal number, and the number comprises the serial number of the byte corresponding to the decimal number in the encrypted data.
Illustratively, each byte of the encrypted data is converted into a corresponding decimal number, and the decimal number of the decimal number is processed according to a set rule, for example, a set number is added before or after the decimal number of the decimal number, and the number can be the serial number of the byte corresponding to the decimal number in the encrypted data.
In a specific example, if the 5 th byte is 0X08, the conversion to the corresponding decimal number is 8, which is a single digit, and the corresponding sequence number of the byte in the encrypted data is 5, then 5 may be added in front of 8, i.e., 58, as a result of the processing of the single digit 8, with 58 replacing 8. The byte expansion for the second time in the instruction determining process in the embodiment of the invention is realized, so that the instruction is more complicated and complicated, and the encryption is better.
Optionally, splitting the target character string to determine a sub-target character string, including: and sequentially selecting a set number of character strings as sub-target character strings from low bytes to split the target character strings.
If the target character string is 308255911243902180373566, the predetermined number of character strings are selected as the sub-target character strings in order from the lower byte, and if the predetermined number is 4, the result of splitting the target character string is 3082, 5591, or 1243 … …. Through the secondary encryption, the encrypted data is more complex and safer, and the data repetition rate is reduced.
In the embodiment of the invention, the encryption process of the data and the expansion process of the data are provided, the purpose of converting the random number into various encryption instructions is realized, the complexity of the encrypted data is increased, the repetition rate of the data is reduced, and the purposes of low repetition rate and good encryption are achieved.

In a specific example, the local device takes an intelligent washing machine as an example, and after a certain key of the intelligent washing machine is clicked, a 4-digit random number, such as 3268, is displayed on a display nixie tube of the intelligent washing machine, and the key can be a power supply start key or the like. The method comprises the steps of encrypting 3268 by using an AES encryption algorithm to obtain first encrypted data, converting each byte of the first encrypted data into a corresponding decimal number, splicing the decimal numbers to determine a first target character string, such as 308255911243902180373566, splitting the first target character string to determine first sub-target character strings 3082, 5591 and 1243 … …, and determining a first corresponding relation between the first sub-target character strings and a local equipment control instruction, such as 3082 for quick washing, 5591 for standard washing, 1243 for powerful washing, 9021 for spin-drying and 8037 for draining. The second corresponding relation between the local control instruction and the working mode of the local equipment can be that the quick washing, the standard washing and the powerful washing correspond to a washing mode, the spin-drying corresponds to a spin-drying mode, and the drainage corresponds to a drainage mode; and sending the second corresponding relation to the intelligent terminal.

In a specific example, the intelligent terminal takes a mobile phone as an example, a first application program matched with the intelligent washing machine is built in the mobile phone, and the interaction process between the mobile phone and the intelligent washing machine is realized through the first application program. The method comprises the steps of displaying 4-digit random numbers on a display nixie tube of the intelligent washing machine, for example 3268, inputting 3268 on a first application program corresponding to a mobile phone, encrypting the 3268 by the mobile phone through an AES encryption algorithm to obtain second encrypted data, converting each byte of the second encrypted data into a corresponding decimal number, splicing the decimal numbers to determine a second target character string, for example 308255911243902180373566, splitting the second target character string to determine second sub-target character strings 3082, 5591 and 1243 … …, and determining a third corresponding relation between the second sub-target character strings and a local equipment control command, for example, 3082 represents quick washing, 5591 represents standard washing, 1243 represents powerful washing, 9021 represents spin-drying and 8037 represents drainage.
In a specific example, fig. 2b shows an interactive schematic diagram of a mobile phone and an intelligent washing machine, 291 represents the mobile phone, 292 represents a display screen of the intelligent washing machine, wherein a display nixie tube is integrated in the display screen, and a random number 3268 displayed on the display nixie tube of the intelligent washing machine is input into a first application program of the mobile phone, so that a display interface of the first application program of the mobile phone displays an optional working mode of the intelligent washing machine, which is used for determining a target working mode through touch or click operations and the like.
It should be noted that, S240 may be executed first, and then S230 is executed, that is, the intelligent terminal receives the random number displayed on the local device; encrypting the random number provided by the local equipment by using a set encryption algorithm to determine second encrypted data; converting each byte of the second encrypted data to a corresponding decimal number; splicing the decimal numbers to determine a second target character string; splitting the second target character string to determine a second sub-target character string; and after the third corresponding relation between the second sub-target character string and the local equipment control command is determined, receiving the second corresponding relation.

And S260, sending the target working mode to the local equipment.
In a specific example, the mobile phone sends the target operation mode to the intelligent washing machine through the first application program, wherein the target operation mode is the quick-washing mode.
