Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiments of the method and the apparatus for block chain-based financial service application management according to the present invention, a flowchart of the method for block chain-based financial service application management is shown in fig. 1. In fig. 1, the block chain-based financial service application management method includes the following steps:
step S01, the user inputs the user name and the password to register the account number to the financial service platform at the user end, after the registration is successful, the financial service platform respectively issues the service number and the service key encrypted by the encryption algorithm to each user end through the wireless communication module: in this step, the user inputs a user name and a password at the user side to register an account number with the financial service platform, and after the account number registration is successful, the financial service platform respectively issues a service number and a service key encrypted by an encryption algorithm to each user side through the wireless communication module. The wireless communication module is any one or combination of any several of a 5G communication module, a 4G communication module, a Bluetooth module, a WiFi module, a GSM module, a CDMA2000 module, a WCDMA module, a TD-SCDMA module, a Zigbee module and a LoRa module. Through setting up multiple wireless communication mode, not only can increase wireless communication mode's flexibility, can also satisfy the demand of different users and different occasions. Especially, when adopting the loRa module, its communication distance is far away, and communication performance is comparatively stable, is applicable to the occasion that requires highly to communication quality. The adoption of the 5G communication mode can achieve high data rate, reduce delay, save energy, reduce cost, improve system capacity and realize large-scale equipment connection. The financial service application management method based on the block chain has various data transmission modes and can meet the requirements of users on various data transmission modes.
The encryption algorithm is DES encryption algorithm, AES encryption algorithm, RSA encryption algorithm, Base64 encryption algorithm, MD5 encryption algorithm, SHA1 encryption algorithm, HMAC encryption algorithm, 3DES encryption algorithm, ECC encryption algorithm, RC2 encryption algorithm, RC4 encryption algorithm, IDEA encryption algorithm or BLOWFSH encryption algorithm. Through data encryption, the safety of data transmission can be improved.
The DES encryption algorithm is a block cipher, data is encrypted by taking 64 bits as a block, the key length of the DES encryption algorithm is 56 bits, and the same algorithm is used for encryption and decryption. The DES encryption algorithm is to keep secret a key, while the public algorithm includes encryption and decryption algorithms. In this way, only a person who has mastered the same key as the sender can interpret the ciphertext data encrypted by the DES encryption algorithm. Thus, deciphering the DES encryption algorithm is actually the encoding of the search key. For a 56 bit long key, the number of operations is 256 if the search is done exhaustively. As the capabilities of computer systems continue to evolve, the security of the DES encryption algorithm is much weaker than it would have been if it had just appeared, yet it can still be considered sufficient from the practical standpoint of non-critical nature. However, the DES encryption algorithm is now only used for authentication of old systems, and new encryption standards are more selected.
The AES encryption algorithm is an advanced encryption standard in cryptography, the encryption algorithm adopts a symmetric block cipher system, the minimum support of the key length is 128, 192 and 256, the block length is 128 bits, and the algorithm is easy to realize by various hardware and software. This encryption algorithm is a block encryption standard adopted by the federal government in the united states to replace the original DES, has been analyzed by many parties and is widely used throughout the world. The AES encryption algorithm is designed to support 128/192/256 bit (/32 ═ nb) data block sizes (i.e., packet lengths); the cipher length of 128/192/256 bits (/32 ═ nk) is supported, and in a 10-bit system, 34 × 1038, 62 × 1057 and 1.1 × 1077 keys are corresponded.
The RSA encryption algorithm is currently the most influential public key encryption algorithm and is generally considered to be one of the most elegant public key schemes at present. The RSA encryption algorithm, the first algorithm that can be used for both encryption and parity signing, is resistant to all cryptographic attacks known so far, and has been recommended by the ISO as the public key data encryption standard. The RSA encryption algorithm is based on a very simple number theory fact: it is easy to multiply two large prime numbers, but it is then desirable, but it is then extremely difficult to factorize their product, so the product can be made public as an encryption key.
The Base64 encryption algorithm is one of the most common encoding modes for transmitting 8-bit byte codes on a network, and the Base64 encoding can be used for transmitting longer identification information under the HTTP environment. For example, in the JAVAPERSISTENCE system HIBEMATE, Base64 was used to encode a longer unique identifier as a string used as a parameter in HTTP forms and HTTP GETTL. In other applications, it is also often necessary to encode the binary data into a form suitable for placement in a URL (including a hidden form field). In this case, the encoding by Base64 is not only relatively short, but also has the property of being unreadable, i.e., the encoded data cannot be directly seen by human eyes.
The MD5 encryption algorithm is a hash function widely used in the field of computer security to provide integrity protection for messages. A brief description of the MD5 encryption algorithm may be: the MD5 encryption algorithm processes incoming information in 512-bit packets, each of which is divided into 16 32-bit sub-packets, and after a series of processing, the output of the algorithm consists of four 32-bit packets, which are concatenated to produce a 128-bit hash value. The MD5 encryption algorithm is widely used for password authentication and key identification of various software. The MD5 encryption algorithm uses a hash function, and its typical application is to digest a piece of information to prevent tampering. A typical application of the MD5 encryption algorithm is to generate a finger print for a piece of Message to prevent "tampering". The use of the MD5 encryption algorithm also prevents "repudiation" by the author of the document if there is a third party certificate authority, a so-called digital signature application. The MD5 encryption algorithm is also widely used for login authentication of operating systems, such as UNIX, various BSD system login passwords, digital signatures, and so on.
The idea behind the SHA1 encryption algorithm is to receive a piece of plaintext and then convert it into a (usually smaller) piece of ciphertext in an irreversible manner, which can also be simply understood as the process of taking a string of input codes (called a pre-map or message) and converting them into a short, fixed-bit output sequence, i.e., a hash value (also called a message digest or a message authentication code). The security of the one-way hash function is that the operation process that generates the hash value has a strong one-way property. If a password is embedded in the input sequence, anyone cannot generate the correct hash value without knowing the password, thereby ensuring its security. The SHA1 encryption algorithm input message is unlimited in length, and the output generated is a 160-bit message digest. The input is processed in 512-bit packets. The SHA1 encryption algorithm is irreversible, anti-collision, and has good avalanche effect.
The digital signature can be realized by a Hash algorithm, the principle of the digital signature is that a plaintext to be transmitted is converted into message digests (different plaintext correspond to different message digests) through a function operation (Hash), the message digests are encrypted and then transmitted to a receiver together with the plaintext, the receiver generates a new message digest for the received plaintext and decrypts and compares the new message digest with the message digest sent by the sender, the comparison result shows that the plaintext is not changed consistently, and if the comparison result shows that the plaintext is tampered.
The HMAC encryption algorithm is a key-dependent Hash operation message authentication Code (Hash-based message authentication Code), and the HMAC encryption algorithm uses a Hash algorithm (MD5, SHA1, etc.) and takes a key and a message as inputs to generate a message digest as an output. The key owned by both the HMAC sender and the HMAC receiver is calculated, and a third party without the key cannot calculate the correct hash value, so that the data can be prevented from being tampered.
The 3DES encryption algorithm is a symmetric DES-based algorithm, and three times of encryption is performed on a block of data by using three different keys, so that the intensity is higher.
The ECC encryption algorithm is also an asymmetric encryption algorithm, the main advantage being that it provides a comparable or higher level of security in some cases using a smaller key than other methods, such as the RSA encryption algorithm. One disadvantage, however, is that the encryption and decryption operations are implemented longer than other mechanisms (the ECC encryption algorithm is more costly to the CPU than the RSA encryption algorithm).
The RC2 encryption algorithm and the RC4 encryption algorithm encrypt large amounts of data with variable-length keys faster than the DES encryption algorithm. The IDEA encryption algorithm is an international data encryption algorithm and provides very strong security using a 128-bit key. The BLOWFSH encryption algorithm uses a variable-length key, the length can reach 448 bits, and the running speed is high.
Step S02 is to authenticate the user who needs financial service according to the service number and the service key: in this step, the user who needs the financial service is authenticated according to the service number and the service key.
Step S03, the financial service platform performs business interaction with the user side: in this step, the financial service platform performs service interaction with the user side, and the service interaction is identified by the unique resource identifier. The unique resource identifier includes a business service name field.
Step S04 calls the service provided by the ethernet blockchain network through the call interface: in this step, the financial service platform calls the service provided by the ethernet block chain network through the calling interface.
For the present embodiment, the step S04 can be further refined, and the detailed flowchart is shown in fig. 2. In fig. 2, the step S04 further includes:
step S41, the user end sends a JSON format calling request to the financial service platform through the wireless communication module: in this step, the user side sends a JSON format calling request to the financial service platform through the wireless communication module.
Step S42, after the financial service platform successfully calls the corresponding service provided by the etherhouse blockchain network, returns a response message based on the JSON format to the user side: in this step, the financial service platform returns a response message based on the JSON format to the user side after successfully calling the corresponding service provided by the ethernet block chain network.

In fig. 3, the device includes an account registration unit 1, an identity authentication unit 2, a service interaction unit 3, and a service invocation unit 4; the account registration unit 1 is used for a user to input a user name and a password at a user end to perform account registration on a financial service platform, and after the registration is successful, the financial service platform respectively issues a service number and a service key which are encrypted by an encryption algorithm to each user end through a wireless communication module; the wireless communication module is any one or combination of any several of a 5G communication module, a 4G communication module, a Bluetooth module, a WiFi module, a GSM module, a CDMA2000 module, a WCDMA module, a TD-SCDMA module, a Zigbee module and a LoRa module; through setting up multiple wireless communication mode, not only can increase wireless communication mode's flexibility, can also satisfy the demand of different users and different occasions. Especially, when adopting the loRa module, its communication distance is far away, and communication performance is comparatively stable, is applicable to the occasion that requires highly to communication quality.
