In order to solve the above-mentioned defect, the inventive concept of the present application is:

according to the embodiment of the application, after the initiation password is injected in the generation stage of the electronic detonator, the second encryption verification code of the N-1 electronic detonator is generated according to the password information of the N-1 electronic detonator and the first encryption verification code of the N-1 electronic detonator, so that the password information is encrypted in each stage of the workflow of the electronic detonator initiation system, and the safety of using the electronic detonator is improved.

In order to illustrate the technical solution of the present application, the following description is made by specific examples.

Referring to fig. 1, fig. 1 is a schematic diagram of an application scenario of an electronic detonator password verification method according to an embodiment of the present application. For convenience of explanation, only the portions relevant to the present application are shown. The application scene comprises: the first terminal device and the second terminal device are in data communication through a wired or wireless mode. For example: wiFi, wireless channel, etc., the communication mode between the first terminal device and the second terminal device is not limited in this embodiment.

In this application scenario, the first terminal device and the second terminal device may include, but are not limited to, a detonation password encryption device, a detonator, an electronic detonator, and the like.

In this embodiment of the present application, the first terminal device may be a detonation password encryption device, and after the detonation password is injected in the generation stage of the electronic detonator, the detonation password encryption device is configured to generate the second encryption verification code of the nth electronic detonator according to the password information of the nth electronic detonator and the first encryption verification code of the N-1 electronic detonator.

The second terminal device may be an initiator, where the initiator is configured to apply for an initiation password from a national industrial electronic detonator password management and control center, and obtain a second encryption verification code of the nth electronic detonator, so as to verify the password information of the nth electronic detonator according to the password information of the nth electronic detonator and the second encryption verification code.

Referring to fig. 2, fig. 2 is a schematic flowchart of an electronic detonator password verification method according to an embodiment of the present application. The execution subject of the method in fig. 2 may be the first terminal device in fig. 1. As shown in fig. 2, the method includes: s201 to S203.

S201, the first terminal equipment acquires the password information of the Nth electronic detonator.

Specifically, N is an integer greater than or equal to 1.

In the embodiment of the application, when the industrial electronic detonator production line needs to generate 10 power generation electronic detonators, the produced first power generation electronic detonator may be called a first electronic detonator, the produced second power generation electronic detonator may be called a second electronic detonator, and the like, the produced 10 th power generation electronic detonator may be called a tenth electronic detonator, that is, the produced nth power generation electronic detonator may be called an nth electronic detonator.

Each time an industrial electronic detonator production line produces an electronic detonator, a user identification code (User Identification code, UID code), a detonation password and a detonator shell code of the electronic detonator need to be written.

In the embodiment of the application, the first terminal equipment is detonation password encryption equipment, and each time the UID code, the detonation password and the detonator shell code of an electronic detonator are written into the industrial electronic detonator production line, namely the UID code, the detonation password and the detonator shell code of the electronic detonator are uploaded to the detonation password encryption equipment until all the UID code, the detonation password and the detonator shell code of the N electronic detonator are uploaded, and the detonation password encryption equipment can acquire the password information of the N electronic detonator.

In other embodiments, after the UID code, the detonation password and the detonator shell code are all written in all N power generation electronic detonators, the industrial electronic detonator production line uniformly uploads the UID code, the detonation password and the detonator shell code to the detonation password encryption equipment, and the detonation password encryption equipment can obtain the password information of the N power generation electronic detonators.

In other embodiments of the present application, the first terminal device is an initiator, the initiator applies for a detonation password to the national industrial electronic detonator password management and control center according to the application information such as UID code, detonator shell code, etc. of the N-generator detonator or some of the N-generator detonators, after the national industrial electronic detonator password management and control center verifies that the application information is qualified, the detonation initiator automatically issues the password information of the electronic detonator to the initiator, and the detonator can obtain the password information of the N-generator detonator.

S202, the first terminal equipment generates a second encryption verification code of the N electronic detonator according to the password information of the N electronic detonator and the first encryption verification code of the N-1 electronic detonator.

Specifically, in the embodiment of the present application, after the first terminal device obtains the password information of the N power generation electronic detonators, a hash function may be used to encrypt the password information of the first electronic detonator, so as to generate summary information of the password information, where the summary information is called a first encrypted verification code of the first electronic detonator. For example: the plaintext (the cipher information of the first electronic detonator) to be encrypted is encrypted into a string of ciphertext (i.e. the Digest information of the cipher information) by using a hash function (Message-Digest algoritm 5, MD5), the string of ciphertext is also called a digital fingerprint, the digital fingerprint has a fixed length, different plaintext can be encrypted into different Digest information by using the MD5, the Digest information obtained by encrypting the same plaintext is consistent, and based on the Digest information obtained by encrypting becomes important information for verifying whether the plaintext has been tampered with or has been leaked by a person. In this embodiment of the present application, other types of hash functions may be further used to encrypt the cryptographic information of the first electronic detonator, for example: secure hash algorithm 1 (Secure Hash Algorithm, sha1), MD4, SHA2, SHA256, etc., embodiments of the present application do not limit the type of hash function.

In this embodiment of the present application, the first terminal device may store the password information of the first electronic detonator and the first encrypted verification code in a block, and for convenience of description, the block is referred to as a first block.

In this embodiment of the present invention, after the first terminal device stores the password information of the first electronic detonator and the first encryption verification code in the first block, the first terminal device may encrypt the password information of the second electronic detonator and the first encryption verification code of the first electronic detonator by using the same hash function as that used for encrypting the password information of the first electronic detonator, so as to generate summary information of the password information of the second electronic detonator, where the summary information is referred to as a second encryption verification code of the second electronic detonator. For example: and encrypting the password information of the second electronic detonator and the first encryption verification code into a string of ciphertext by adopting the MD5, wherein the string of ciphertext is the second encryption verification code of the second electronic detonator. The first terminal device stores the first encryption verification code of the first electronic detonator, the password information of the second electronic detonator and the second encryption verification code in the second block. Based on the above, the second block not only contains the password information of the second electronic detonator and the second encryption verification code, but also indirectly contains the information of the first block.

According to the encryption method, the first terminal device may encrypt the password information of the nth electronic detonator and the first encryption verification code of the nth-1 electronic detonator (in order to distinguish the second encryption verification code of the nth-1 electronic detonator from the second encryption verification code of the nth electronic detonator), by using the same hash function as that used for encrypting the password information of the first electronic detonator, and the second encryption verification code of the nth-1 electronic detonator is referred to as the first encryption verification code of the nth-1 in the embodiment of the application, so as to generate summary information of the password information of the nth electronic detonator, where the summary information is referred to as the second encryption verification code of the nth electronic detonator. The first terminal device stores the first encryption verification code of the N-1 electronic detonator, the password information of the N electronic detonator and the second encryption verification code in the N block. Based on this, the nth block contains information of all the previous blocks.

In this embodiment, the first terminal device combines all the blocks from the first block to the nth block to form the blockchain. The leakage or modification of the password information of any one electronic detonator on the blockchain can change the abstract information of the following block, namely the second encryption verification code, so that when the password information in the blockchain is verified, whether the password information of all electronic detonators are leaked or modified can be verified only by verifying the abstract information of the Nth block, namely the second encryption verification code of the Nth electronic detonator, and the password information of all electronic detonators is conveniently verified.

It should be noted that, when the first terminal device in the embodiment of the present application encrypts the N electronic detonators respectively, the hash functions used may be the same or different, and the above embodiment is to use the same hash function to encrypt the N electronic detonators respectively for illustration.

In this embodiment of the present application, after the first terminal device generates the second encrypted verification code of the nth electronic detonator, the signature information of the nth electronic detonator may also be generated according to the second encrypted verification code of the nth electronic detonator.

Specifically, in the embodiment of the present application, in order to ensure that the password information sent by the first terminal device to the second terminal device is actually sent by the first terminal device and further ensure that the password information sent by the first terminal device is not revealed, so as to cause modification, after the first terminal device generates the first encryption verification code of the first electronic detonator (the first encryption verification code for generating the first electronic detonator is described in the above embodiment, and is not described herein), the first terminal device encrypts the first encryption verification code again, so as to generate signature information of the first electronic detonator. In the embodiment of the application, the first encryption verification code is encrypted again, and the method for generating the signature information of the first electronic detonator is not limited.

Illustratively, the first terminal device may re-encrypt the first encrypted authentication code using an asymmetric encryption algorithm. For example: the asymmetric encryption algorithm may be an elliptic curve digital signature algorithm, a DSA (Digital Signature Algorithm, DSA) encryption/decryption algorithm, or the like, and the embodiment of the present application does not limit the type of the asymmetric encryption algorithm.

In this embodiment of the present application, the asymmetric encryption algorithm in the first terminal device may generate a set of a public key and a private key, where the public key and the private key are in pairs, and the public key corresponding to the private key may be calculated by using the private key. The method for generating the public key and the private key by the asymmetric encryption algorithm is not limited in the embodiment of the application.

In the embodiment of the application, the first terminal device encrypts the first encryption verification code again by using the private key to generate signature information of the first electronic detonator.

In the embodiment of the application, the terminal device stores the password information, the first encryption verification code and the signature information of the first electronic detonator in the first block.

In this embodiment, after the first terminal device generates the second encrypted verification code of the second electronic detonator (the second encrypted verification code for generating the second electronic detonator has been described in the foregoing embodiment, which is not described herein again), the first terminal device may also encrypt the second encrypted verification code of the second electronic detonator again by using the asymmetric encryption algorithm, so as to generate the signature information of the second electronic detonator. The asymmetric encryption algorithm used by the first terminal device to encrypt the second encrypted verification code of the second electronic detonator again may be the same as the asymmetric encryption algorithm used to encrypt the first encrypted verification code of the first electronic detonator again, or may be different from the asymmetric encryption algorithm used to encrypt the first encrypted verification code of the first electronic detonator again.

In one embodiment, if the asymmetric encryption algorithm used by the first terminal device to encrypt the second encrypted verification code of the second electronic detonator is the same as the asymmetric encryption algorithm used to encrypt the first encrypted verification code of the first electronic detonator, the private key used when encrypting the second encrypted verification code of the second electronic detonator again is different from the private key used to generate the signature information of the first electronic detonator.

In one embodiment, if the asymmetric encryption algorithm used by the first terminal device to encrypt the second encrypted verification code of the second electronic detonator is different from the asymmetric encryption algorithm used to encrypt the first encrypted verification code of the first electronic detonator, the private key used when encrypting the first encrypted verification code of the second electronic detonator is definitely different from the private key used when generating the signature information of the first electronic detonator.

In the embodiment of the application, the first terminal device stores the first encryption verification code and the signature information of the first electronic detonator, and the password information, the second encryption verification code and the signature information of the second electronic detonator in the second block.

In this embodiment of the present application, after the first terminal device generates the second encryption verification code of the nth electronic detonator according to the method for encrypting by using the asymmetric encryption algorithm (the second encryption verification code for generating the nth electronic detonator is described in the foregoing embodiment, which is not described herein in detail), the second encryption verification code of the nth electronic detonator is encrypted again by using the asymmetric encryption algorithm which is the same as or different from the signature information for generating the N-1 electronic detonator, so as to generate the signature information of the nth electronic detonator.

In the embodiment of the application, the first terminal equipment stores the first encryption verification code and signature information of the N-1 electronic detonator, and the password information, the second encryption verification code and signature information of the N electronic detonator in the N block.

Referring to fig. 3, fig. 3 is a schematic flowchart of a method for generating a second encrypted verification code of an nth electronic detonator according to an embodiment of the present application. The execution subject of the method in fig. 3 may be the first terminal device in fig. 1. As shown in fig. 3, the method includes: s301 to S302.

S301, a first terminal device acquires a preset time period sequence of an N-th electronic detonator.

Specifically, in the embodiment of the present application, the preset time period sequence of the nth electronic detonator is a continuous time period starting from a time point corresponding to the password information of the nth electronic detonator. For example: the first terminal equipment obtains a continuous time period by taking 10:00 as a starting point and 15 minutes as an interval time when the moment corresponding to the password information of the first electronic detonator is 10:00. Such as 10:00 to 10:15, 10:15 to 10:30, 10:30 to 10:45, etc. The embodiment of the application does not limit the time and the interval time corresponding to the password information of the first electronic detonator.

In this embodiment of the present application, the preset time period sequence for acquiring other electronic detonators by the first terminal device may refer to the preset time period sequence for acquiring the first electronic detonator, which is not described herein. It should be noted that: the time and interval time corresponding to the password information of the other electronic detonators obtained by the first terminal device may be the same as or different from the time and interval time corresponding to the password information of the first electronic detonator.

In this embodiment of the present application, the total time length of the preset time period sequence of the first electronic detonator is longer than the preset time delay of the first electronic detonator, for example: the preset time delay of the first electronic detonator is 40 minutes, and the time period is at least 3, so that the total time length of the preset time period sequence of the first electronic detonator is longer than the preset time delay of the first electronic detonator. The preset time delay is 50 minutes, and the time period is at least 4, so that the total time length of the preset time period sequence of the first electronic detonator can be longer than the preset time delay of the first electronic detonator. The total duration of the preset time period sequences of other electronic detonators in the embodiment of the application is also longer than the preset time delay of other electronic detonators. The preset time delay in the embodiment of the application is the time for delay initiation of the electronic detonator. The embodiment of the application does not limit the preset time delay.

In this embodiment of the present invention, the total time length of the preset time period sequence of the nth electronic detonator is longer than the preset time delay of the nth electronic detonator, so that when the first terminal device generates the dynamic encryption verification code of the nth electronic detonator according to the preset time period sequence of the nth electronic detonator in the subsequent S302, the dynamic encryption verification code of the nth electronic detonator can be generated within the preset time delay of the nth electronic detonator. For example: the preset time delay of the nth electronic detonator is 40 minutes, and the interval between each time period in the preset time period sequence is 15 minutes, so that the preset time period sequence of the nth electronic detonator obtained by the first terminal device at least has 3 continuous time periods, for example: the 3 consecutive time periods are 10:00 to 10:15, 10:15 to 10:30, 10:30 to 10:45.

The first terminal equipment generates the dynamic verification code of the Nth electronic detonator in 3 continuous time periods, and the dynamic encryption verification code of the Nth electronic detonator can be generated in the preset time delay of the Nth electronic detonator. If the preset time period sequence of the nth electronic detonator obtained by the first terminal device has only 2 continuous time periods, for example: 2 continuous time periods are 10:00 to 10:15, and 10:15 to 10:30, generating a dynamic verification code of the N electronic detonator within the first 30 minutes of the preset time delay of the N electronic detonator, generating a fixed verification code of the N electronic detonator within the last 10 minutes of the preset time delay of the N electronic detonator, and generating the dynamic verification code of the N electronic detonator to form a complete dynamic verification code of the N electronic detonator within the first 30 minutes of the preset time delay of the N electronic detonator.

It should be noted that: in the embodiment of the application, the number of time periods in the preset time period sequence of the electronic detonator is related to the preset time delay and the interval time of the electronic detonator. Based on this, the number of time periods in the preset time period sequence of the other electronic detonators obtained by the first terminal device may be the same as or different from the number of time periods in the preset time period sequence of the first electronic detonator. For example: the preset time delay of the first terminal equipment is 40 minutes, the interval time is 15 minutes, and the number of time periods is 3. The preset time delay of other terminal equipment is 40 minutes, the interval time is 15 minutes, or the preset time delay is 50 minutes, the interval time is 20 minutes, and the number of time periods is 3. For example: the preset time delay of the first terminal equipment is 40 minutes, the interval time is 15 minutes, and the number of time periods is 3.
