In one embodiment, step 101 receives an unlocking request of an operator for a lock on a bank note box, and determining a lock parameter of a to-be-unlocked tool may include:
And verifying the biological characteristic information of the operator, and determining the lockset parameters of the tool to be unlocked after the biological characteristic information passes the verification.
In the specific implementation, in step 101, in order to reduce human participation in the management of the banknote box lockset of the self-service device of the bank, a dynamic coded lock can be installed on the banknote box, and an unlocking code (OTC One Time Code) of the dynamic coded lock is disposable, after unlocking and locking operations are performed each time, the original unlocking code is invalid, and a new unlocking code needs to be generated when unlocking the banknote box next time, so that illegal molecules can be stopped from cracking the codes, and the security of the banknote box is improved. Before receiving an unlocking request of an operator for a lock on a bank note box, a bank administrator can firstly establish an unlocking task and input task information in the unlocking task, wherein the task information can comprise, for example: the number and name of the designated operator, and corresponding lockset parameters, the operator can input the number and name to log in the system, select an unlocking task and issue an unlocking request, and after receiving the unlocking request of the operator, the operator can be prompted to input biometric information, wherein the biometric information can comprise: fingerprint, voice, face image and other information, the relevant information input by the operator can be verified according to the biological characteristic information of the operator stored in the system in advance, and for example, the method can comprise the following steps: fingerprint identification, voice identification, facial image identification and the like, verifying whether an operator designated in an unlocking task is consistent with an operator initiating an unlocking request, if so, executing a subsequent unlocking step, and if not, prompting that verification is not passed and unlocking fails.

Fig. 2 is a schematic flowchart of step 102 in fig. 1, and in an embodiment, in step 102, combining lock parameters of a to-be-unlocked tool to determine initial parameters of an unlocking code of the to-be-unlocked tool may include:

Step 1022: and combining the lockset number with the random number after the character type conversion and the locking check code, and determining initial parameters of an unlocking code of the lockset to be unlocked.
In specific implementation, the lock number, the random number and the locking check code can be combined to determine initial parameters of the unlocking code of the to-be-unlocked tool, for example: the string type random number 22222222 and the locking check code 33333333 can be converted into the char array with the length of 32, 32323232323232323333333333333333, and then the char array and the lock number 040404040404040404040404 are combined into hexadecimal initial parameters, namely 04040404040404040404040432323232323232323333333333333333, the initial parameters are only simple combination among the lock number, the random number and the locking check code, the password characteristic is not possessed, the security is low, and the initial parameters are further encrypted through various encryption algorithms.

Step 1031: encrypting initial parameters of the unlocking code based on a national encryption algorithm SM3, and reorganizing the encrypted initial parameters;
Step 1032: adding the security password into the encrypted and recombined initial parameters, and carrying out secondary encryption on the encrypted and recombined initial parameters based on a national encryption algorithm SM 4;

dividing the encrypted initial parameters into two groups of data with the same bit number;
and performing exclusive OR operation on the two groups of data, and recombining the encrypted initial parameters.
In specific implementation, in step 1031, the cryptographic algorithm SM3 is a hash algorithm, belongs to a hash algorithm, and may encrypt the initial parameters in step 102 based on the cryptographic algorithm SM3, for example, may be: firstly filling initial parameters, enabling the data length of the filled initial parameters to BE an integer multiple of 512, then grouping the filled initial parameters into a group according to 512 bits, finally performing iterative compression to obtain a group of hash value data, namely C015EC CD168F792C5CEC4CC4E537A5542BF2325E2378EC2B79A896949FD4BE6E, thus completing primary encryption of the initial parameters, then recombining the encrypted initial parameters, dividing the encrypted initial parameters into two groups of data with the same bit number, performing exclusive OR operation on the two groups of data, and halving the data length after recombination to obtain hexadecimal data, namely EBE7DE9335F795072544DA507AE31B3A, thus completing recombination of the encrypted initial parameters.
In the specific implementation, in step 103, the security password (DMK) may be applied to a security service system of a bank when the lock is activated for the first time, for further encrypting the unlocking code, a transmission password (TMK) may be applied first, then the security password is generated according to the transmission password, in step 1032, the DMK may be added into the encrypted and recombined initial parameter, and based on the national encryption algorithm SM4, the encrypted and recombined initial parameter is encrypted for the second time, where the national encryption algorithm SM4 is a block encryption algorithm, the block length of which is 128 bits, and the key length is also 128 bits. The encryption algorithm and the key expansion algorithm both adopt a 32-round nonlinear iteration structure, encryption operation is carried out by taking a word (32 bits) as a unit, each iteration operation is a round of transformation function, and initial parameters after secondary encryption can be as follows: F1F7281564FB0C11EA85F2C32BEFC3E4.
In the specific implementation, step 1033, APHash is a hash algorithm, which can convert the input of any content into an encryption mode of the output with the same length, and can decompose the multiplication into bit operation and addition and subtraction, so that the hash distribution effect is outstanding, and the method has outstanding advantages in the occasion with very strict security requirements. The initial parameters after secondary encryption can be firstly converted into char arrays with the length of 32, namely 7049705550564953545270664867494969655653705067515066697067516952, then odd numbers and even numbers in the arrays are separated, each character affects the final result according to bit operation, so that an intermediate calculated value is obtained, then the intermediate calculated value and 100000000 are subjected to remainder taking operation, an unlocking code with 8 digits after APHash operation, namely 37313465, can be determined as the final unlocking code, thus a password with higher security can be obtained through a security password (DMK), a national encryption algorithm SM3, SM4 and a APHash algorithm, communication automation is realized in the whole process, human participation is not needed, and the security and unlocking efficiency of the unlocking code are improved.
In one embodiment, after determining the unlock code of the to-be-unlocked lock in step 103, the method further includes:
after the lock is opened, the unlocking code is disabled.
When the method is implemented, after the unlocking code of the lockset to be unlocked is determined, under the condition that the system communication is normal, the unlocking code can be sent to the lockset to be unlocked, whether the unlocking code automatically generated by the lockset to be unlocked is consistent with the unlocking code or not is judged, if the unlocking code is consistent with the unlocking code, the lockset can be unlocked, if the unlocking code is inconsistent, verification failure is prompted, the unlocking code can be sent to an operator under the emergency conditions such as abnormal system communication, if the unlocking code finally input by the operator is consistent with the unlocking code of the lockset to be unlocked, the lockset can be unlocked, and if the unlocking code is inconsistent, verification failure is prompted, and the unlocking failure is prompted. After the lockset is opened, the unlocking code is invalidated, and the next time an operator initiates an unlocking request to the lockset, the process needs to be re-executed to generate a new unlocking code.
The following presents a specific example to facilitate understanding of how the present invention may be practiced.
Firstly, a dynamic coded lock is installed on a banknote box of a bank self-service device, a bank administrator establishes an unlocking task in advance, task information is input in the unlocking task, and then the following steps are executed:
The first step: receiving an unlocking request of an operator to the lockset, verifying whether a corresponding unlocking task exists, prompting the operator to input a fingerprint after the unlocking request passes, identifying the fingerprint input by the operator, verifying whether the designated operator in the unlocking task is consistent with the operator initiating the unlocking request, if so, executing a second step, and if not, rejecting the unlocking request;
And a second step of: combining the lockset number, the random number generated based on the unlocking request and the locking check code generated when the lockset is locked last time, and determining initial parameters of the unlocking code of the to-be-unlocked tool;
And a third step of: encrypting the unlocking code once based on a national encryption algorithm SM3, and reorganizing the encrypted unlocking code;
Fourth step: applying a security password (DMK) to a security service system of a bank when the lockset is activated for the first time, adding the DMK into the encrypted and recombined initial parameters, and carrying out secondary encryption on the encrypted and recombined initial parameters based on a national encryption algorithm SM 4;
fifth step: carrying out APHash operation on the initial parameters after the secondary encryption, and determining an unlocking code after APHash operation as an unlocking code of the tool to be unlocked;
sixth step: the unlocking code is sent to the tool to be unlocked, whether the unlocking code automatically generated by the tool to be unlocked is consistent with the unlocking code or not is judged, if so, the unlocking code is determined to be effective, the lockset can be unlocked, if not, verification failure is prompted, and the unlocking is failed;
seventh step: after the lockset is opened, the unlocking code is invalidated, and the next time an operator initiates an unlocking request to the lockset, the steps one to six need to be re-executed to generate a new unlocking code.
