The following is a description of the steps shown in fig. 3.
Step 301: the request server obtains a processing server address of the processing server.
Wherein the request server and the processing server together form a data processing system, wherein the data processing system may implement a remote procedure call RPC, in particular a protocol that requests services from a remote computer program over a network without requiring knowledge of underlying network technology. The RPC protocol assumes the existence of certain transmission protocols, such as TCP or UDP, to carry information data between communication programs; the main functional goal of RPC is to make it easier to build distributed computing (applications) without losing the semantic simplicity of local calls while providing powerful remote call capabilities. In the data processing system formed by the request server and the processing server together, the request server can transmit the coded RPC request message to the processing server, the processing server returns a result message or a confirmation message to the request server after executing the RPC request message, and the TCP protocol in a long connection mode can be selected to obtain higher data processing efficiency.
In some embodiments of the present application, for application types where the amount of data traffic is small, single links substantially meet the requirements of data processing. In some embodiments, the data to be processed may be received by multiple connections, that is, each connection has its own private sending and receiving buffers, so that when a large amount of data is transmitted, the data is scattered in different connection buffers, which results in better throughput efficiency, and avoids lengthening the waiting time of the user.
Step 302: based on the processing server address, the requesting server sends an authentication request to the processing server address, wherein the authentication request includes the requesting server address and a public key that matches the processing server.
In some embodiments of the present application, the address of the request server is denoted as address s, the address of the processing server is denoted as address p, and before performing network communication, the request server needs to obtain the address p of the processing server, and send, through an anonymous protocol, the address s of the request server and a public key corresponding to the request server and matched with the processing server to perform authorization authentication, so as to ensure that privacy information of a user is not revealed.
Step 303: the processing server detects the request server address based on the request server address and a public key matched with the processing server in response to the authentication request.
In some embodiments of the present application, in order to achieve information anonymization in an RPC call process and protect privacy security of a request server and a processing server, the processing server and the request server need to be encapsulated into virtual addresses through an anonymity protocol, and meanwhile, a function method of the processing server is encapsulated into virtual addresses, specifically, referring to fig. 4, fig. 4 is a schematic process diagram of obtaining an anonymized address corresponding to the request server in an embodiment of the present application, and specifically includes the following steps:
step 401: the matching private key is configured for the requesting server.
When the request server generates the private key, a 32-byte number with the size between 1 and 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4141 is randomly selected as the private key.
Step 402: and calculating an uncompressed public key corresponding to the private key through an elliptic curve cryptography algorithm, and determining a first hash value in the uncompressed public key.
In some embodiments of the present invention, taking the first hash value as an example with a length of 256 bits, when a 256-bit hash value is used, an elliptic curve cryptography algorithm (ECDSA-secp 256k 1) may be used to calculate an uncompressed public key corresponding to the private key, and the obtained uncompressed public key is 65 bytes in total, including: 1 byte 0x04, 32 bytes are x coordinates, and 32 bytes are y coordinates.
Step 403: and carrying out conversion processing on the first hash value in the uncompressed public key based on the anonymity protocol matched with the request server to obtain the anonymity address corresponding to the request server.
In some embodiments of the present invention, the transforming the first hash value in the uncompressed public key to obtain the anonymous address corresponding to the request server may be implemented by:
based on a first hash value in the uncompressed public key, calculating a second hash value of the RACE original integrity check message abstract, adding a version number of an anonymous protocol matched with the request server into the second hash value of the RACE original integrity check message abstract, and obtaining a first hash value processing result; the fixed length hash value in the first hash value processing result is circularly calculated to obtain a second hash value processing result, wherein the second hash value can be a 160-bit hash value, the fixed length in the first hash value processing result can be 256 bits, and it should be noted that when the data processing method provided by the application is executed, the fixed length in the first hash value, the second hash value and the first hash value processing result can be adjusted according to different scenes of data processing, for example: in the financial data processing scenario, the first hash value is a 256-bit hash value, the second hash value is a 160-bit hash value, and the fixed length of the first hash value processing result is 256 bits, whereas in the identity data processing scenario, since the security requirement of data transmission is reduced, the first hash value is a 128-bit hash value, the second hash value is an 80-bit hash value, and the fixed length of the first hash value processing result is 128 bits.
In some embodiments of the present application, taking the first hash value with a length of 256 bits as an example, performing transformation processing on the hash value with a length of 256 bits in the uncompressed public key to obtain the anonymous address corresponding to the request server may be implemented in the following manner:
calculating a 160-bit hash value of the RACE original integrity check message digest based on the hash value with the length of 256 bits in the uncompressed public key; adding the version number of the anonymous protocol matched with the request server into the 160-bit hash value of the RACE original integrity check message abstract to obtain a first hash value processing result; circularly calculating a hash value with a length of 256 bits in the first hash value processing result to obtain a second hash value processing result; and adding 4 bytes of the head part based on the second hash value processing result with the first hash value processing result to obtain the anonymous address corresponding to the request server. As shown in fig. 4, the hash algorithm used in the embodiment of the present application may be a secure hash algorithm (SHA SecureHashAlgorithm), such as SHA256, SHA512, or the like, or may be an original integrity check message digest (RIPEMD, RACE Integrity Primitives Evaluation Message Digest), such as RIPEMD160, or may be any other hash algorithm, such as a Keccak algorithm, or the like, which is not specifically limited in this application. The SHA series of algorithms includes a series of cryptographic hash functions, which may include variants of SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512, for example. The SHA256 algorithm is mainly applicable to a digital signature algorithm (Digital Signature Algorithm DSA) defined in a digital signature standard (Digital Signature Standard, DSS). The principle of calculating the message digest by adopting the algorithm can be as follows: for messages of arbitrary length (calculated as bits), which may be a public key having a length of 130 bits in the present embodiment, SHA256 generates a 32 byte length of data, called a message digest (i.e., the first target value in the present embodiment is obtained). Therefore, the processing server may perform a first hash operation on the public key with a data length of 130 bits by using the SHA256 algorithm, to obtain a first target value corresponding to the public key, where the data length of the first target value is 64 bits, that is, 32 bytes.
In some embodiments of the present application, when the SHA256 algorithm is used, the SHA256 algorithm has the following characteristics: 1. information cannot be recovered from the message digest; 2. two different messages will not produce the same message digest. Therefore, the uniqueness of the public key in the processing server can be ensured through the SHA256 algorithm, so that the processing server cannot reversely push out the public key when obtaining the authentication request, and the data to be processed of the user is ensured not to be leaked.
Referring to fig. 5, fig. 5 is a schematic diagram of a process of calculating an address of a request server by a processing server in the embodiment of the present application, where in a financial data processing scenario, a first hash value is a 256-bit hash value, a second hash value is a 160-bit hash value, and a fixed length of the first hash value is 256 bits, specifically including the following steps:
step 501: the processing server obtains locally stored anonymity protocols.
Step 502: the processing server randomly selects a private key, calculates an uncompressed public key corresponding to the private key through an elliptic curve cryptography algorithm, and determines a hash value with a length of 256 bits in the uncompressed public key.
Step 503: the processing server calculates a 160-bit hash value of the RACE original integrity check message digest based on the 256-bit hash value in the uncompressed public key.
Step 504: and the processing server adds the version number of the anonymity protocol matched with the request server in the 160-bit hash value of the RACE original integrity check message abstract to obtain a third hash value processing result.
Step 505: and the processing server circularly calculates a hash value with the length of 256 bits in the third hash value processing result to obtain a fourth hash value processing result.
Step 506: the processing server adds the 4 bytes of the header of the fourth hash value processing result to the third hash value processing result to obtain the request server address.
In some embodiments of the present application, the processing server detects the request server address based on the request server address and a public key matched with the processing server in response to the authentication request, by:
the processing server responds to the authentication request and acquires an anonymous protocol matched with the processing server; calculating a target request server address based on an anonymous protocol matched by the processing server and a public key matched by the processing server; when the target request server address is consistent with the request server address carried by the authentication request, determining that the request server is consistent with the anonymous protocol version of the processing server. After receiving the authorization authentication request sent by the address S of the request server, the processing server compares the public key of the request server with the local anonymous protocol version number calculation address, if the public key of the request server is the same as the local anonymous protocol version number calculation address, the processing server indicates that the same anonymous protocol is used, the address S is recorded in the address book of the request client of the anonymous protocol, and the address mapping relation of all public access functions in data processing is returned.
In some embodiments of the present application, when the target request server address is inconsistent with the request server address carried by the authentication request, determining that the anonymous protocol version of the request server and the anonymous protocol version of the processing server are different; the processing server sends out refusal request information or the notification request server sends out notification information to realize the change of anonymous protocol version. The request server and the processing server have a pair of public keys and private keys, the private keys are used for generating authentication information, and the public keys are used for verifying the legality of the information. Therefore, the privacy security of the user can be avoided, the disclosure of the data to be processed is avoided, the consistency of anonymous protocol versions of the processing server and the request server can be ensured, and the convenience of the user in using the data processing method provided by the application is ensured. Meanwhile, the replacement anonymous protocol version can be polled for version replacement according to the replacement anonymous protocol version list, and maintenance personnel of the request server can be informed of manually replacing the anonymous protocol version, so that information processing time of the request server and the processing server is saved, and a user obtains better use experience. It should be noted that the anonymous protocol version may be provided by a service architecture operator, and the processing server and the request server may periodically replace the anonymous protocol version, or may purchase an anonymous protocol version with a higher security level from the service architecture operator.
Step 304: and detecting the address of the request server, and when the target request server address calculated by the processing server is consistent with the address of the request server, sending a function address mapping relation to the request server by the processing server.
Step 305: the request server processes the data to be processed through the function address mapping relation to obtain the virtual address of the data to be processed, and sends the virtual address of the data to be processed to the processing server so as to realize anonymous processing of the data to be processed.
In some embodiments of the present application, after sending the virtual address of the data to be processed to the processing server, after executing the remote procedure call, the requesting server may receive the processing result sent by the processing server; and processing the data to be processed based on the anonymous address of the request server and the function address mapping relation to obtain a processing result of the data to be processed, thereby completing the processing of the data to be processed. After the request server obtains the address mapping relation of the function of the processing server, the corresponding function of the local plaintext request can be converted into an address form and then sent to the processing server, and the request server can also reversely check the corresponding function through the address mapping relation of the function to carry out actual processing, so that the leakage of the address of the request server and the address of the processing server in the data processing process can be effectively avoided.
The embodiment of the application can be implemented by combining Cloud technology, wherein Cloud technology refers to a hosting technology for integrating hardware, software, network and other series resources in a wide area network or a local area network to implement calculation, storage, processing and sharing of data, and can also be understood as a general term of network technology, information technology, integration technology, management platform technology, application technology and the like applied based on a Cloud computing business model. Background services of technical network systems require a large amount of computing and storage resources, such as video websites, picture websites and more portal websites, so cloud technologies need to be supported by cloud computing.
It should be noted that cloud computing is a computing mode, which distributes computing tasks on a resource pool formed by a large number of computers, so that various application systems can acquire computing power, storage space and information service as required. The network that provides the resources is referred to as the "cloud". Resources in the cloud are infinitely expandable in the sense of users, and can be acquired at any time, used as needed, expanded at any time and paid for use as needed. As a basic capability provider of cloud computing, a cloud computing resource pool platform, referred to as a cloud platform for short, is generally called infrastructure as a service (IaaS, infrastructure as a Service), and multiple types of virtual resources are deployed in the resource pool for external clients to select for use. The cloud computing resource pool mainly comprises: computing devices (which may be virtualized machines, including operating systems), storage devices, and network devices.
The processing server address, the request server address, the anonymity protocol and the function address mapping relation can be sent to the cloud network, so that corresponding service side equipment can acquire the processing server address, the request server address, the anonymity protocol and the function address mapping relation from the cloud network. When the service side equipment passes the authentication, the data processing service can be reproduced by using the address of the processing server, the address of the request server, the anonymous protocol and the mapping relation of the function address, so that the supervision of the data processing process by the supervision department is facilitated.
The data processing method provided in the present application is further described below in connection with different implementation scenarios. Referring to fig. 6, fig. 6 is a schematic diagram of a front end display of the data processing method provided in the present application. Wherein terminals (e.g., terminal 10-1 and terminal 10-2 in fig. 1) are provided with clients capable of displaying software for making financial payments, such as clients or plug-ins for financial activities by or through virtual or physical resources. The user can conduct loan service from the financial institution through the corresponding client. The method can be applied to cross-industry cooperation scenes of financial wind control scenes, for example, a business terminal is a bank A and a bank B respectively.
The bank a server and the bank B server may both be servers under the micro-service architecture (ATF Total Application Framework). The ATF TARS framework is a high-performance RPC development framework based on name service using TARS protocol, and is matched with an integrated service management platform, so that individuals or enterprises can be helped to quickly construct stable and reliable distributed application in a micro-service mode. The TARS framework is an open source project summarizing the practical achievements of TAFs. The TARS framework is a framework which has the advantages of easy use, high performance and service management. The design idea of the protocol layer at the bottommost layer of the TARS framework is to unify the protocols of service network communication, and develop a unified protocol which supports multiple platforms, expandability and automatic generation of protocol codes in an IDL mode. In the development process, a developer only needs to pay attention to the content of a protocol field of communication and does not need to pay attention to the implementation details of the protocol field, so that the problems of whether the protocol to be considered can be used in a cross-platform manner, whether compatibility, expansion and the like are possibly required in the process of developing the service are greatly solved. After acquiring the data using the TAF, the response structure is disassembled into a common js object. Through the WUP-proxy plugin, the service layer can take the intermediate result of this common js object. The communication interface is based on the JCE protocol, which is the bottom-most part of the TAF framework. Each communication interface defines a request structure and a response structure based on JCE protocol. Invoking WUP service refers to TAF service of a series of interfaces provided by the service, a platform layer builds a WUP basic service, the association relation between the service name and the TAF service is set in the configuration of the WUP basic service, and the front end is proxied to the TAF service of the service through the service name and the WUP basic service. The TAF service is used for providing service processing thread class to count various call information reported by the service.
As shown in fig. 1 in conjunction with the foregoing, the data processing method provided in the embodiment of the present application may be implemented by a corresponding cloud device, for example: servers of different business parties (e.g., bank a server 10-1 and bank B server 10-2) are connected directly to the service architecture operator server 200 at the cloud. It should be noted that the service architecture operator server 200 may be a physical device, or may be a virtualized device in a cloud network.
Wherein, bank a receives the user's loan request shown in table 1:
TABLE 1
To further control risk, bank a wishes to screen out those users who have low deposit or low credit before formally issuing the loan, and the deposit information and credit information of the users are out of the business scope of bank a.
At the same time bank B has a set of users with deposits above 10 ten thousand yuan and corresponding credit scores, see table 2. However, the banks A and B do not establish a data exchange mechanism, so that the user information is not safe to directly transmit through the network, and address information and data are easily acquired by interception attack, so that user data are revealed.
TABLE 2
When a user needs to transact related financial business, information transmission is carried out through the server of the bank A and the server of the bank B, and when financial service is provided, the data processing method provided by the application can be utilized, aiming at different types of data processing scenes, the processing server and the request server can be packaged into virtual addresses, and the function method of the processing server is packaged into the virtual addresses, so that anonymization of data processing is ensured, and privacy leakage of the user is prevented.
