Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and in particular to a method, apparatus, electronic device, and storage medium for generating random number seeds. Background Technology

[0002] With the rapid development of computer technology, random numbers have permeated all aspects of people's lives. For example, users can use verification codes issued by servers for identity verification, or use dynamic verification codes generated by web pages for identity verification.

[0003] However, existing random number generation methods often require only a user and a blockchain node to generate random numbers, which raises the possibility that the generated random number results can be tampered with. Furthermore, the fact that only one node participates in the generation of random numbers makes the generated random number results unreliable. Summary of the Invention

[0004] This disclosure provides a method, apparatus, electronic device, and storage medium for generating random number seeds, enabling all consensus nodes in a blockchain to participate in the generation of random numbers, thereby improving the reliability of the random number generation process and results.

[0005] In a first aspect, embodiments of this disclosure provide a method for generating a random number seed, the method comprising:

[0006] Upon receiving encrypted random numbers corresponding to the random number generation requests from each consensus node, the encrypted random numbers are stored on the blockchain; and,

[0007] All encrypted random numbers are sent to each consensus node, and the corresponding key information is broadcast after the consensus node receives the encrypted random numbers.

[0008] Based on preset rules and corresponding key information, the consensus node processes all received encrypted random numbers to obtain the target random number seed.

[0009] Secondly, embodiments of this disclosure also provide a random number seed generation device, the device comprising:

[0010] The data storage and transmission module is used to store the encrypted random number on the blockchain when it receives the encrypted random number corresponding to the random number generation request from each consensus node; and to send all the encrypted random numbers to each consensus node, and broadcast the corresponding key information after the consensus node receives the encrypted random number.

[0011] The random number seed acquisition module is used to process all the encrypted random numbers received by the consensus node based on preset rules and corresponding key information to obtain the target random number seed.

[0017] The technical solution of this embodiment, upon receiving encrypted random numbers corresponding to random number generation requests from various consensus nodes, stores these encrypted random numbers on the blockchain and sends them to each consensus node, while also broadcasting the key information corresponding to each consensus node. This allows each consensus node to process all received encrypted random numbers based on preset rules and the corresponding key information to obtain the target random number seed. Based on this technical solution, all consensus nodes in the blockchain can participate in the random number generation process, ensuring the fairness and security of the random number generation process, thereby improving the credibility of the random number generation process and its results.

[0023] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the drawings, not the entire structure.

[0024] Example 1

[0025] Figure 1 This is a flowchart of a random number seed generation method provided in an embodiment of this disclosure. This embodiment is applicable to situations where, upon receiving a random number generation request, the random number seed is generated jointly by various nodes. This method can be executed by the random number seed generation device in this embodiment. The system can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal or PC. The device can be configured in a computing device or in a webpage.

[0026] Before introducing this technical solution, an illustrative application scenario can be provided. This disclosed technical solution can be applied to any scenario involving the generation of random numbers, such as mobile SMS verification codes, dynamic verification codes on web pages, and web page lotteries. For example, it can be applied to web page lotteries, where multiple random numbers are often generated. In this case, blockchain technology can be used to generate these random numbers.

[0027] It should be noted that existing random number generation methods often involve a single blockchain node receiving random number information from multiple nodes, concatenating the received random number information in chronological order, and then performing a hash operation on the concatenated information. The resulting hash value is used as the random number seed. Since all operations are performed by the same blockchain node, it is impossible to guarantee that the node is not malicious and that the results could be manipulated. Furthermore, the participants in random number generation are only the user and a single blockchain node, failing to reflect the value of blockchain as a multi-party collaborative scenario. Therefore, existing random number generation methods need to be improved. The random number seed generation method provided in this embodiment specifically includes the following steps:

[0028] S110. Upon receiving the encrypted random number corresponding to the random number generation request from each consensus node, the encrypted random number is stored on the blockchain; and all encrypted random numbers are sent to each consensus node, and the corresponding key information is broadcast after the consensus node receives the encrypted random number.

[0029] In a blockchain, a consensus node can be a special type of ordinary node. Besides performing the functions of a regular time node, a consensus node is used to reach consensus and update data. A blockchain is a chain of blocks, each storing specific information, linked together in chronological order of their creation. A random number generation request can be understood as a request sent by a requesting node to instruct the generation of random numbers. Encrypted random numbers are data obtained by encrypting the generated random numbers by the consensus node. Key information can be understood as parameters used to convert plaintext data to ciphertext data or vice versa. It's understood that for different consensus nodes, key information can be private or public, such as a private key and a public key. Key information can be used to encrypt or decrypt the generated encrypted random numbers, etc.

[0030] Specifically, after receiving the encrypted random numbers corresponding to the random number generation requests from each consensus node, the system stores the received encrypted random numbers on the blockchain and sends all received encrypted random numbers to each consensus node, while simultaneously broadcasting the corresponding key information of each consensus node. For example, each consensus node could generate encrypted random numbers, store the generated encrypted random numbers on the blockchain, and simultaneously broadcast the generated encrypted random numbers and their corresponding key information to other consensus nodes.

[0031] It should be noted that the key information is the encryption information used by consensus nodes when generating encrypted random numbers. It can be encrypted using symmetric encryption and asymmetric encryption algorithms. The specific encryption method can be preset according to the requirements. Since the key information of each consensus node may be different, after the consensus node sends the encrypted random number, each consensus node will send the corresponding key information to other consensus nodes so that other consensus nodes can decrypt the encrypted random number based on the key information.

[0032] Based on the above technical solution, before receiving the encrypted random numbers corresponding to the random number generation requests from each consensus node, the method further includes: generating the random number generation request based on the requesting node and sending it to each consensus node, so that the corresponding consensus node generates a random number to be used based on the random number generation request; processing the random number to be used into plaintext data to be stored; encrypting the corresponding plaintext data to be stored based on the key of each consensus node to obtain the encrypted random number corresponding to each consensus node, and sending each encrypted random number to the requesting node.

[0033] In this context, the requesting node can be the node that generates the random number generation request. The random number to be used can be understood as the random number generated by each consensus node based on the random number generation request, and the corresponding plaintext data to be stored can be the original random number generated by each consensus node.

[0034] Specifically, when a user needs to generate random numbers, they can send a corresponding random number generation command. Upon receiving the command, the requesting node generates a random number generation request. Alternatively, the system can automatically generate a random number generation command when pre-defined conditions are triggered, such as when a user performs a certain operation or a pre-defined time condition is met. The requesting node then sends the generated random number generation request to each consensus node, enabling each node to generate a random number to be used based on the request. The generated random number is then stored as plaintext data. After generating the random number, each consensus node encrypts it using a corresponding key to obtain an encrypted random number, which is then sent to the requesting node.

[0035] For example, when a user needs to authenticate, they can send an authentication command to the server. After receiving the command, the requesting node generates a random number generation request and sends it to each consensus node, so that each consensus node generates a corresponding random number to be used. Each consensus node encrypts the generated random number using key information to obtain an encrypted random number, and then sends the encrypted random number to the requesting node.

[0036] It should be noted that the random numbers to be used generated by each consensus node based on the random number generation request can be the same or different, and the encryption method can be symmetric encryption or asymmetric encryption. When the encryption method is symmetric encryption, each consensus node can use the same key to encrypt the random number to be used to generate an encrypted random number. When the encryption method is asymmetric encryption, each consensus node can use the public key to encrypt the random number to be used to obtain an encrypted random number.

[0037] S120. Based on preset rules and corresponding key information, the consensus node processes all received encrypted random numbers to obtain the target random number seed.

[0038] The preset rules can be pre-defined rules for processing data. The target random number seed can be understood as the initial value used to generate pseudo-random numbers.

[0039] Specifically, based on the pre-set data processing rules and the response key information, each consensus node processes all the received encrypted random numbers to obtain the target random number seed. It can be understood that in order to ensure that the random number seeds generated by each consensus node are the same, it is necessary to process the decrypted random numbers to be used according to the rules to obtain the final random number seed.

[0040] Based on the above technical solution, the step of processing all received encrypted random numbers by the consensus node based on preset rules and corresponding key information to obtain a target random number seed includes: decrypting the corresponding encrypted random numbers based on each key information to obtain plaintext information to be used corresponding to each encrypted random data; if each plaintext information is consistent with the corresponding plaintext data to be stored, then obtaining the random number to be used; and processing the random number to be used according to preset rules to obtain the target random number seed.

[0041] The plaintext information to be used can be the information obtained by decrypting the encrypted random number using the key.

[0042] Specifically, after obtaining the encrypted random numbers and key information broadcast by each consensus node, the corresponding encrypted random numbers are decrypted according to the key information of each consensus node to obtain the plaintext information to be used for each consensus node. The obtained plaintext information to be used is then matched with the already stored plaintext data to be stored. If the match is consistent, the random numbers to be used for each consensus node are obtained, and each random number to be used is processed according to the preset rules to obtain the target random number seed.

[0043] It should be noted that the preset rules include, but are not limited to, hash algorithms, VRF (Verifiable Random Functions) algorithms, etc. That is, the random number obtained by the hash algorithm can be transformed into a fixed-length output by the hash algorithm, or the random number can be processed by the VRF algorithm to obtain a verifiable pseudo-random output, etc.

[0044] Based on the above technical solution, the method further includes: determining the storage method corresponding to the target random number seed; if the storage method is interval block generation, then the target random number seed is generated periodically and stored in the corresponding block in the blockchain, so that when a random number generation request is received, the target random number seed is obtained according to the timestamp of each block.

[0045] It should be noted that different random number seed generation methods can be determined according to different needs. When users need to quickly obtain multiple random number seeds, the instant generation method will cause users to wait too long, making it impossible for users to obtain the required random number seeds immediately, thereby reducing the user experience. Therefore, different random number seed generation methods will exist to meet different user needs.

[0046] The storage method can be a method used to store the random number seed. The timestamp can be understood as the digital signature data corresponding to a block in the blockchain and the digital signature data of the generated random number seed. It's important to understand that since each block and random number seed is generated at a different time, the timestamps of different blocks and different random number seeds are completely different.

[0047] Specifically, if the current target random number seed is stored using interval block generation, meaning multiple random number seeds may need to be provided to the user simultaneously, then random number seeds are generated periodically according to a preset method and stored in the corresponding blocks. Upon receiving a random number generation request, the target random number seed can be retrieved based on the timestamps corresponding to each block and the random number seed. For example, to improve the efficiency of random number generation, a random number seed can be generated every n blocks and stored in the (n+1)th block. Then, upon receiving a random number generation request, the random number seed can be retrieved sequentially based on the preset interval and the timestamps corresponding to each block and random number seed.

[0048] Based on the above technical solution, it further includes: if the storage method is to determine and store the target random number seed when a random number generation request is received, then determine the target random number seed corresponding to the random number generation request and store it on the blockchain.

[0049] Specifically, if the current random number seed generation method is to generate and store the random number seed upon receiving a random number generation request, then the target random number seed corresponding to the random number generation request is generated according to a preset method, and the generated random number seed is stored in the blockchain.

[0050] The technical solution of this disclosure provides a variety of random number seed storage methods, with different storage methods corresponding to different random number seed generation methods. This allows the solution to meet user needs under different requirements, thereby improving the generation efficiency of random number seeds.

[0051] Based on the above technical solution, it also includes: broadcasting the target random number seed corresponding to each consensus node to other consensus nodes.

[0052] Specifically, each consensus node, after receiving the encrypted random number and corresponding key from other consensus nodes, can process the encrypted random number according to the key and preset rules to obtain the target random number seed. After generating the target random number seed, it is broadcast to other nodes.

[0053] It should be noted that, since the random number generation method provided in this embodiment only involves blockchain nodes and no external factors intervene, the generation process is completely recorded on the chain and bound to the consensus mechanism of the blockchain network, ensuring complete distribution and full traceability. Therefore, in order to ensure the correctness of the random number seeds generated by each consensus node, it is necessary to broadcast the random number seeds generated by each consensus node to other nodes.

[0054] Based on the above technical solutions, it is possible to combine Figure 2 The technical solution disclosed herein will be further described, such as... Figure 2 As shown, users can choose the random number generation method according to their needs. Users can choose between instant generation or pre-generation. When the user chooses instant generation, the requesting node, upon receiving a request to generate random numbers from an external source, broadcasts the request to all other consensus nodes. The other consensus nodes generate random numbers *r*, form plaintext information according to a specified format, and encrypt it using a symmetric encryption key or an asymmetric encryption public key through the information processing module to obtain *R*. It should be noted that the specified format is set by the user according to their needs. To ensure the consistency of the generated information format, the format for the plaintext information generated by each consensus node needs to be pre-defined. Each consensus node then sends R to the requesting node. After collecting all R values, the requesting node broadcasts or writes all R values ​​directly into a block and sends them to all consensus nodes. Each consensus node, upon receiving all R values, broadcasts or writes them directly into a block and sends its symmetric key or private key to other nodes. Other nodes, after receiving the keys from each node, first decrypt all R values ​​to obtain plaintext information, discard information that does not conform to the specified plaintext format, obtain all random numbers, and then process the random numbers according to preset rules to obtain a random number seed S, which is then broadcast to other nodes. When a user needs to generate multiple random number seeds in advance, the specific method for generating random number seeds is consistent with the method for generating them on the fly. However, after obtaining the random number seeds, the requesting node will encrypt the obtained random number seeds again and store the encrypted random number seeds in the block. It should be noted that, to ensure fairness in the random number seed generation process, the technical solution provided in this embodiment also changes the requesting node according to preset rules. The preset rules can be determined by the user according to their needs, such as meeting a preset duration or meeting the required number of random number seeds to be generated.

[0055] The technical solution of this embodiment, upon receiving encrypted random numbers corresponding to random number generation requests from various consensus nodes, stores these encrypted random numbers on the blockchain and sends them to each consensus node, while also broadcasting the key information corresponding to each consensus node. This allows each consensus node to process all received encrypted random numbers based on preset rules and the corresponding key information to obtain the target random number seed. Based on this technical solution, all consensus nodes in the blockchain can participate in the random number seed generation process, ensuring the fairness and security of the random number seed generation process, thereby improving the credibility of the random number seed generation process.

[0068] Based on the above technical solution, the storage method determination module is further configured to: if the storage method is to determine and store the target random number seed when a random number generation request is received, then determine the target random number seed corresponding to the random number generation request and store it on the blockchain.
