Example 1
Fig. 1 is a flowchart of a data processing method according to a first embodiment of the present invention. The embodiment of the invention can be applied to the case of encrypting and decrypting data, and the method can be executed by a data processing device, wherein the data processing device can be realized in the form of hardware and/or software, and the data processing device can be configured in an electronic device, such as a transmitting device.
Referring to the data processing method shown in fig. 1, executed by a transmitting apparatus, includes:
s101, generating a random time string according to the current time.
In this embodiment, the current time may refer to a real current time, i.e. a local real current time. The random time string may be a character string, where the characters may include, but are not limited to, a current time character and a character that is different from the current time, etc.
In an alternative embodiment, the current time includes at least two types of time, and connectors exist between the different types of time; generating a random time string according to the current time, including: and replacing the connector in the current time with a character different from the current time to obtain a random time string.
The time type may include, but is not limited to, year, month, day, hour, minute, second, etc. The character different from the current time is a character of a character type different from the current time. For example, if the character type at the current time is a digital character, the character different from the current time may be a randomly generated character, including but not limited to alphabetic characters, symbolic characters, and the like; wherein the alphabetic symbols are, for example, "A", "b", and "J", etc.; the symbolic character is for example "+|! "," @ "and" # ", etc. It should be noted that the connectors of different types of time may be set by the skilled person according to the actual requirement or practical experience, and the present invention is not limited thereto, and for example, the connectors may be "-", "/", etc. Illustratively, if the type of time in the current time includes year, month, and day, the current time is "2023-05-18", the random string generated may be "2023E05B18".
Further, before obtaining the random time string, the method further comprises: characters different from the current time are added at the start position and the end position of the current time. For example, if the type of time in the current time includes year, month and day, the current time is "2023-05-18", the generated random string may be "D2023E05B18C".
It can be appreciated that by adopting the technical scheme, a random time string with higher data complexity can be obtained under the condition that the current time is unchanged, so that the complexity of the data ciphertext obtained according to the random time string is improved, and the cracking difficulty of the data ciphertext is increased; the complexity of the data processing result can be increased, and meanwhile, the value and the format of the current time are kept unchanged, so that the efficiency of the receiving device for acquiring the corresponding current time from the random time string is improved.
S102, encrypting the data original text to be encrypted according to the random time string to obtain the data ciphertext.
In this embodiment, the data primitive to be encrypted may be an unencrypted data string to be currently transmitted; the data ciphertext is a data character string obtained by encrypting the data original text to be encrypted according to the random time string.
Optionally, encrypting the data original text to be encrypted according to the random time string to obtain the data ciphertext, including: determining a target key according to the random time string and a preset key; and encrypting the data original text to be encrypted by adopting the target key to obtain the data ciphertext.
The preset key can be set by a technician according to actual requirements or practical experience, and the invention is not limited to the preset key. The target key may be a key for encrypting the data original to be encrypted.
Specifically, fusing the random time string with a preset key to obtain a target key; and encrypting the data original text to be encrypted according to the target key and a preset encryption algorithm to obtain the data ciphertext. It should be noted that the preset encryption algorithm is not limited in the present invention, and for example, the preset encryption algorithm may be DES (Data Encryption Standard ) algorithm, AES (Advanced Encryption Standard, advanced encryption standard) algorithm, IDEA (International Data Encryption Algorithm ) algorithm, and the like.
It can be understood that by adopting the technical scheme and adopting the random time string to obtain the target key, the complexity of the target key can be increased, so that the decoding device cannot correctly decrypt the data ciphertext under the condition that only the original key is obtained, and the security of the data ciphertext is improved.
In an alternative embodiment, a preset fusion mode is used to fuse the random time string and the preset secret key, and the preset fusion mode can be, for example, an insertion mode, an alternative mode, a splicing mode, a splitting combination mode and the like. The inserting method is to insert the random time string into the preset key. The alternative is to add a random time string to the preset key in a way of replacing the character strings with the same length in the preset key. The splicing mode is to splice the random time string with the preset key. The splitting method is to split the random time string into a plurality of sub-random time strings and insert the sub-random time strings into different positions of the preset key.
Taking an insertion mode as an example for illustration, the determining process of the target key comprises the following steps: inquiring a numerical value corresponding to a character which is different from the current time in the random time string; determining a first numerical sum among numerical values corresponding to characters different from the current time in the random time string; taking the modulus of the first numerical value and the length of the preset key, and taking the modulus result as first position information; and inserting the random time string into the preset key according to the first position information to obtain the target key. For example, if the random time string is "D2023E05B18C", the preset key is "5E2E065869260hc8f1830E9abb ac52", and the values corresponding to "D", "E", "B", and "C" in the query random time string are 4, 5, 2, and 3, respectively, the first sum is 14, and the length of the preset key is 32; taking the modulus of the first numerical value sum 14 and the length 32 of the preset key to obtain a modulus taking result 14; taking the modulus result 14 as first position information; after inserting the random time string in the 14 th character in the preset key, the target key "5E2E065869260hD2023E05B18Cc8f1830E9abb ac52" is obtained.
By way of example, the first location information may be determined by the following formula:
N＝M mod KL；
wherein N represents first location information; m represents a first numerical sum; KL denotes the length of the preset key.
S103, adding the random time string at a preset position of the data ciphertext to obtain a data processing result.
In this embodiment, the preset position may be set by a technician according to an actual requirement or practical experience, which is not limited in the present invention. The data processing result may be a data string obtained by adding a random time string to the data key.
And S104, sending the data processing result to the receiving equipment so that the receiving equipment decrypts the data processing result.
In this embodiment, the receiving device may be a device communicatively connected to the transmitting device. Specifically, the receiving device determines a random time string and a data ciphertext from the data processing result according to the data processing result; and decrypting the data ciphertext according to the random time string to obtain a data original text.
According to the embodiment of the invention, a random time string is generated according to the current time; encrypting the data original text to be encrypted according to the random time string to obtain a data ciphertext; adding the random time string at a preset position of the data ciphertext to obtain a data processing result; and sending the data processing result to the receiving device so that the receiving device decrypts the data processing result. According to the technical scheme provided by the embodiment of the invention, the receiving equipment can determine whether the data processing result is valid according to the corresponding time of the random time string in the data processing result, so that the data text can be obtained only when the data processing result is valid, the receiving equipment can receive correct and valid data, and the data processing efficiency is improved; if the random time string in the data processing result is tampered, the receiving device cannot acquire the correct data original text from the data processing result, so that the safety of the data original text is improved.
Example two
Fig. 2 is a flowchart of a data processing method according to a second embodiment of the present invention. The embodiment of the invention can be applied to the case of encrypting and decrypting data, and the method can be executed by a data processing device, wherein the data processing device can be realized in the form of hardware and/or software, and the data processing device can be configured in an electronic device, such as a receiving device.
In the embodiments of the present invention, the descriptions of other embodiments may be referred to in the portions not described in detail.
Referring to the data processing method shown in fig. 2, executed by a receiving apparatus, includes:
s201, receiving a data processing result from a transmitting device; the data processing result is generated by the following steps: generating a random time string according to the current time; encrypting the data original text to be encrypted according to the random time string to obtain a data ciphertext; and adding the random time string at a preset position of the data ciphertext to obtain a data processing result.
In this embodiment, the transmitting device may be a device communicatively connected to the receiving device. The current time may refer to the actual current time, i.e. the local actual current time. The random time string may be a character string, where the characters may include, but are not limited to, a current time character and a character that is different from the current time, etc. The data primitive to be encrypted may be an unencrypted data string currently waiting to be transmitted. The data ciphertext is a data character string obtained by encrypting the data original text to be encrypted according to the random time string. The preset position can be set by a technician according to actual requirements or practical experience, and the invention is not limited to the preset position. The data processing result may be a data string obtained by adding a random time string to the data key.
S202, splitting the data processing result to obtain a random time string and a data ciphertext.
Specifically, a certain algorithm is adopted to split the data processing result, so that a data ciphertext of a random time string is obtained.
Optionally, splitting the data processing result to obtain a random time string and a data ciphertext, including: splitting the data processing result into a random time string and a data ciphertext from a preset position of the data processing result.
It can be understood that by adopting the technical scheme, the cracking equipment can not accurately split the data processing result to obtain an accurate random time string and a data ciphertext under the condition that the preset position is not obtained, so that the safety of the random time string and the data ciphertext is improved; the receiving device can split the data processing result according to the preset position appointed by the encryption device, and the efficiency of splitting the data processing result is improved under the condition of ensuring correct splitting.
S203, decrypting the data ciphertext according to the random time string to obtain a data original text.
Specifically, a certain algorithm is adopted, and the data ciphertext is decrypted according to the random time string, so that the data original text is obtained.
Optionally, decrypting the data ciphertext according to the random time string to obtain the data original text, including: determining a time difference value between the time when the receiving device receives the data processing result and the time corresponding to the random time string; checking whether the time difference value is within the validity period; and if the time difference value is within the validity period, determining a target key according to the random time string and the preset key, and decrypting the data ciphertext by adopting the target key.
The time corresponding to the random time string may be the current time in the step of generating the random time string according to the current time. The validity period can be the effective time length of the characterization data processing result, and can be set by a technician according to actual demands or practical experience, for example, one year, one month, one day and the like. The preset key can be set by the technician according to the actual requirement or practical experience, and the invention is not limited to this. The target key may be a key for encrypting the data original to be encrypted. It should be noted that, the preset decryption algorithm for decrypting the data ciphertext and the preset encryption algorithm for encrypting the data original are inverse algorithms, so the target key can also be used for decrypting the data ciphertext.
Specifically, characters among different types of time in the random time string are replaced by connectors, and/or characters at the starting position and the ending position of the random time string are removed, so that time corresponding to the random time string is obtained; determining a time difference value between the time when the receiving device receives the data processing result and the time corresponding to the random time string; if the time difference is greater than the valid period, discarding the data processing result if the time difference exceeds the valid period; if the time difference is smaller than or equal to the validity period, fusing the random time string with a preset key to obtain a target key; and decrypting the data ciphertext according to the target key and a preset decryption algorithm to obtain a data original text.
Illustratively, if the random time string is "D2023E05B18C", then the time corresponding to the random time string is "2023-05-18"; the time of receiving the data processing result by the receiving equipment is 2023-06-18, and the time difference is 31 days; if the validity period is 365 days, the time difference value is smaller than the validity period, a target key is determined according to the random time string and the preset key, and the target key is adopted to decrypt the data ciphertext.
In an alternative embodiment, a preset fusion mode is used to fuse the random time string and the preset secret key, and the preset fusion mode can be, for example, an insertion mode, an alternative mode, a splicing mode, a splitting combination mode and the like. The inserting method is to insert the random time string into the preset key. The alternative is to add a random time string to the preset key in a way of replacing the character strings with the same length in the preset key. The splicing mode is to splice the random time string with the preset key. The splitting method is to split the random time string into a plurality of sub-random time strings and insert the sub-random time strings into different positions of the preset key.
Taking an insertion mode as an example for illustration, the determining process of the target key comprises the following steps: inquiring a numerical value corresponding to a character which is different from the current time in the random time string; determining a first numerical sum among numerical values corresponding to characters different from the current time in the random time string; taking the modulus of the first numerical value and the length of the preset key, and taking the modulus result as first position information; and inserting the random time string into the preset key according to the first position information to obtain the target key. For example, if the random time string is "D2023E05B18C", the preset key is "5E2E065869260hc8f1830E9abb ac52", and the values corresponding to "D", "E", "B", and "C" in the query random time string are 4, 5, 2, and 3, respectively, the first sum is 14, and the length of the preset key is 32; taking the modulus of the first numerical value sum 14 and the length 32 of the preset key to obtain a modulus taking result 14; taking the modulus result 14 as first position information; after inserting the random time string in the 14 th character in the preset key, the target key "5E2E065869260hD2023E05B18Cc8f1830E9abb ac52" is obtained.
It can be appreciated that by adopting the technical scheme, whether the time difference value is within the validity period can be checked before the data ciphertext is decrypted, so that the data ciphertext is still decrypted under the condition that the time difference value exceeds the validity period, and the data processing efficiency is improved.
The embodiment of the invention receives the data processing result from the sending equipment; the data processing result is generated by the following steps: generating a random time string according to the current time; encrypting the data original text to be encrypted according to the random time string to obtain a data ciphertext; adding the random time string at a preset position of the data ciphertext to obtain a data processing result; splitting the data processing result to obtain a random time string and a data ciphertext; and decrypting the data ciphertext according to the random time string to obtain a data original text. According to the technical scheme provided by the embodiment of the invention, the receiving equipment can determine whether the data processing result is valid according to the corresponding time of the random time string in the data processing result, so that the data text can be obtained only when the data processing result is valid, the receiving equipment can receive correct and valid data, and the data processing efficiency is improved; if the random time string in the data processing result is tampered, the receiving device cannot acquire the correct data original text from the data processing result, so that the safety of the data original text is improved.
