The data processing method of the disclosed embodiment will be described in detail below with reference to fig. 2 based on the scenario described in fig. 1.
Fig. 2 schematically illustrates a flow chart of a data processing method according to an embodiment of the present disclosure.
As shown in fig. 2, this embodiment includes operations S210 to S230, and the data processing method may be performed at a server in the public cloud.
In operation S210, data from the first system is input to a preconfigured template engine in response to a data conversion request, and data in a target format is generated.
In operation S210, the data exchange request refers to a request for source data conversion, such as converting request data of a service system (i.e., a first system) into a unified data format, and then generating data in a target format, such as data in a format required by a target system for communication, using a pre-configured template engine, such as a Freemaker transaction template, based on the data in the unified format, where the target system may include a second system.
In operation S220, the data in the target format is converted into at least one data of a preset length, and the at least one data of the preset length is data-signed using an asymmetric encryption algorithm.
In operation S220, for example, data in a target format of any length is converted into data of a specific length, such as the data is converted into binary and grouped, and compressed into a digest of a fixed length, such as the message digest using the cryptographic algorithm SM3, where SM3 is a message digest, and a message of any length can be output to a message of a fixed length and is irreversible. Meanwhile, an asymmetric encryption algorithm, such as an SM2 algorithm, is used for carrying out data signing, and the signing speed and the secret key generating speed of the SM2 algorithm are high.
In operation S230, in response to receiving the symmetric key agreed with the second system and generated by the first system using the symmetric encryption algorithm, the data with the at least one preset length after the data signing is encrypted according to the symmetric key, so as to obtain at least one ciphertext data and a check value of the at least one ciphertext data, and the at least one ciphertext data and the check value of the at least one ciphertext data are sent to the second system.
In operation S230, the symmetric key is generated by the requester (the first system), and the symmetric key is agreed with both sides of the target system (i.e., the second system); and the symmetric encryption algorithm, such as SM4 algorithm, is adopted to encrypt the data, and 16-system ciphertext data is output, and the security of data transmission can be greatly improved by adopting the encryption mode.
In operation S230, a check value of at least one ciphertext data is also determined, for example, an SM3 algorithm is adopted to generate a MAC value (i.e., a check value) for the whole ciphertext data, and the MAC value is sent to the second system, so that the second system knows the check value (e.g., the first check value) of the data originally sent, thereby calculating the check value (e.g., the second check value) of the data received by the system (the second system), comparing the first check value with the second check value to determine whether the received data is complete, thereby ensuring the integrity in the data transmission process and preventing data tampering.
The data processing method provided by the embodiment can be deployed in public cloud, the public cloud is service for providing resources for the public, the resources are not private, a user can use cloud service through the Internet, the cost is low compared with private cloud, and meanwhile, a network link from the public cloud to the user (second system) is realized, and compared with the network link from the public cloud to the private cloud to the user (second system), the network link from the public cloud to the private cloud to the user (second system) is simpler.
Fig. 3 schematically illustrates a schematic diagram of generating ciphertext data and a check value, according to an embodiment of the disclosure. Referring to fig. 3, a first system 310 sends data and a generated symmetric key agreed with a second system to a data processing device 320. The data processing apparatus mainly performs data signing and encryption, as shown in operations S210 to S230 in fig. 1, and then forwards ciphertext data and a corresponding check value (such as at least one ciphertext data and a check value of at least one ciphertext data) to the second system 330. After receiving the ciphertext data and the corresponding check values, the second system 330 may calculate the check value of the at least one ciphertext data by an inverse algorithm of the symmetric encryption algorithm in response to receiving the at least one ciphertext data and the first check value of the at least one ciphertext data, to obtain a second check value; under the condition that the first check value is consistent with the second check value, a symmetrical secret key agreed with the second system and generated by the first system through a symmetrical encryption algorithm is called; decrypting the at least one ciphertext data based on the symmetric key to obtain at least one plaintext data; and performing verification signature processing on the at least one plaintext data, and generating response data corresponding to the at least one ciphertext data according to the at least one plaintext data if the verification is passed; thereby returning reply data to the first system 310.
By utilizing the data processing method provided by the embodiment, a complete safety authentication scheme is provided in the aspect of safety transmission of data, and the safety of data transmission among different systems is ensured.
According to the data processing method provided by the embodiment, the data from the first system is processed, such as the data from the first system is subjected to data signature, for example, the data subjected to data signature is encrypted by utilizing the symmetric key which is agreed by the first system and the second system and is generated by the first system, and the ciphertext data and the corresponding check value are sent to the second system together, so that the safety of data transmission is greatly improved, and the development cost is reduced.
The data processing method further comprises the following steps: before inputting data received from the first system to a preconfigured template engine to generate data in a target format in response to a data conversion request: and in response to detecting that the business transaction task starts to be executed, sending a symmetric key updating request to the first system so that the first system adopts a symmetric encryption algorithm to update the symmetric key agreed with the second system.
According to the data processing method, the symmetric key is automatically updated at any time in the transaction process by updating the symmetric key, so that a complete updating mechanism is provided, the symmetric key is prevented from being unchanged in the communication process of the first system and the second system, and the security of the key is improved.
For example, a first time of communication between a first system and a second system is initiated, a symmetric key is adopted as A, and data theft occurs in the first time of communication; if the symmetric key is unchanged, then each subsequent communication from the first system to the second system is stolen Fang Daoqu; if so, an updating mechanism of the data processing method of the embodiment is added, namely, a request for updating the symmetric key is sent to the first system in response to the detection of the start of execution of the business transaction task, so that the first system adopts a symmetric encryption algorithm to update the symmetric key agreed with the second system; in the subsequent communication process from the first system to the second system, the difficulty of data theft is increased, and each time the first system to the second system communication cannot be realized by the theft method, the data can be stolen Fang Daoqu.
The data from the first system includes a target second system; the data processing method further comprises the following steps: carrying out identity authentication on data from a first system to obtain a first identity authentication result; responding to the received response data from the second system, and carrying out identity authentication on the response data from the second system to obtain a second identity authentication result; and determining whether the second system is a target second system according to the first identity authentication result and the second identity authentication result.
For example, in the process of sending at least one ciphertext data and a check value of the at least one ciphertext data to the second system, the check value is intercepted by a pirate, and the pirate processes the data and returns response data to the first system; however, since the response data returned by the thief is not returned by the target second system, after the identity authentication is performed on the response data, the obtained authentication result, that is, the second identity authentication result, cannot be matched with the first identity authentication result, and the second system is determined to be not the target second system. And when the second system is determined not to be the target system, countermeasures such as stopping communication, updating a secret key and the like are taken, so that the safety of data transmission is further improved.
For another example, the data from the first system may be authenticated to obtain a first authentication result; responding to the received response data from the second system, and carrying out identity authentication on the response data from the second system to obtain a second identity authentication result; and comparing the first identity authentication result with the second identity authentication result, and determining that the second system is a target second system if the comparison result is matched or consistent, thereby ensuring the safe transmission of data.
According to the data processing method provided by the embodiment, by comparing the first identity authentication result with the second identity authentication result corresponding to the response data, whether the response data from the second system is from the target second system can be determined, so that a complete identity authentication mechanism is provided in the process of communication between the first system and the second system, and the safety of data transmission is improved.
Fig. 4 schematically shows a flow chart of a data processing method according to another embodiment of the present disclosure.
As shown in fig. 4, this embodiment includes operations S410 to S440, and the data processing method may be performed at the terminal.
In operation S410, in response to receiving the at least one ciphertext data and the first check value of the at least one ciphertext data, the check value of the at least one ciphertext data is calculated using an inverse of the symmetric encryption algorithm, resulting in a second check value.
For example, the inverse algorithm of the cryptographic algorithm SM3 is adopted to calculate the MAC values of all the received ciphertext data, and the second check value is used for comparing with the first check value, so as to ensure the integrity of the data transmission process and prevent tampering.
In operation S420, in case that the first check value is identical to the second check value, a symmetric key agreed with the second system generated by the first system using the symmetric encryption algorithm is invoked.
The use of a symmetric key agreed upon by the second system generated by the first system using a symmetric encryption algorithm facilitates further discovery of whether the received at least one ciphertext data is from the first system.
In operation S430, the at least one ciphertext data is decrypted based on the symmetric key to obtain at least one plaintext data.
For example, the decryption is performed by using a cryptographic algorithm based on the symmetric key, for example, the SM4 algorithm is used to decrypt at least one ciphertext data to obtain at least one plaintext data.
In operation S440, a verification signature process is performed on at least one plaintext data, and in case of passing the verification, response data corresponding to the at least one ciphertext data is generated from the at least one plaintext data.
For example, the SM3 algorithm is used to calculate the digest of at least one plaintext data, and the signature is decrypted using the public key, that is, the signature is verified, and in the case of verification, response data corresponding to at least one ciphertext data is generated from at least one plaintext data.
In some embodiments, the format of the reply data may also be changed to a data format required by the first system in the public cloud based on a pre-configured Freemaker transaction objective.
By utilizing the data processing method provided by the embodiment, a complete safety authentication scheme is provided in the aspect of safety transmission of data, and the safety of data transmission among different systems is ensured.
Performing verification signature processing on at least one plaintext data, and generating response data corresponding to at least one ciphertext data according to the at least one plaintext data in the case of passing the verification, including: invoking a public key agreed by the first system and the second system, decrypting the signature of at least one plaintext data, and obtaining a first signature result; decrypting the signature of at least one plaintext data by adopting an inverse algorithm of a symmetric encryption algorithm to obtain a second signature result; determining whether the at least one plaintext data passes verification according to the first signature result and the second signature result; and generating response data corresponding to the at least one ciphertext data according to the at least one plaintext data if the verification is passed.
