[0040] Figure 1 It is a flowchart of the method for generating a security password of a medical device in the first embodiment of the present invention;

[0041] Figure 2 It is a block diagram of the structure of the device for generating a security password of a medical device in the third embodiment of the present invention.

[0042] The following specific embodiments will further illustrate the present invention in conjunction with the above drawings. SPECIFIC EMBODIMENTS

[0043] For the convenience of understanding the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] Embodiment 1

[0047] Please refer to Figure 1 , which shows the method for generating a security password for a medical device in the first embodiment of the present invention. The method includes steps S10 to S12.

[0048] Step S10: Obtain the unique identification code of the medical device for which the password is to be assigned, and combine the unique identification code with a first preset character, and then generate a first hash value through a preset hash algorithm.

[0049] Among them, the unique identification code of the medical device is the unique identifier assigned to the medical device during the production process. For a medical device, the unique identification code can be obtained by reading the hardware code on the device main board through a chip reader built into the device, or by obtaining a specific serial number from the device's system configuration file. These serial numbers are strictly encoded and recorded in accordance with specifications during the production process of the medical device to ensure their uniqueness and accuracy.

[0050] Combine the unique identification code of the medical device with a custom first preset character, and generate a first hash value through a preset hash algorithm. Among them, the first preset character can be a fixed string or some other preset and specific characters; specifically, in the embodiment of the present invention, the MD5 algorithm can be selected to calculate and generate a unique first hash value. The MD5 algorithm is selected because of its relatively fast calculation speed, which can meet the real-time requirements for generating the security password of the device. By combining the identification code of the medical device with the custom first preset character, the security of password generation is greatly improved.

[0051] Step S11: Select a preset number of character elements from the first hash value according to a first preset selection rule, and use the character elements to form the user initial password of the medical device;

[0052] Among them, character elements are extracted from the first hash value according to the first preset selection rule to form the user's initial password. The first preset selection rule can be random or based on a certain specific logic. For example, the first n characters in the first hash value can be selected, one character can be selected every m characters, or characters at specific positions can be selected, etc. Specifically, in the embodiments of the present invention, the first preset selection rule selects characters based on a specific order. In specific implementation, the high and low bits of the first hash value are determined, and a preset number of character elements are sequentially and alternately selected from the high bit to the low bit of the first hash value. Finally, the selected character elements are combined in the selection order or other predefined orders to form the user's initial password for the medical device. This password is used for the login operation of medical staff. In addition, if the character length of the extracted character elements does not meet the length of the user's initial password, custom characters are used to fill it until the length of the user's initial password is met.

[0053] Step S12: Combine the first hash value with the second preset character and generate a second hash value through a preset hash algorithm, and then use the second preset selection rule to select a preset number of character elements from the second hash value to form the maintenance password of the medical device.

[0054] Among them, the obtained first hash value and the second preset character are used to generate a second hash value through a hash algorithm, and character elements are extracted from the second hash value according to the second preset selection rule to form the maintenance password. Among them, the second preset selection rule is different from the first preset selection rule. Exemplarily, the second preset selection rule also selects character elements in a preset selection order, but is different from the first preset selection rule to achieve the separation of the user's initial password and the maintenance password. The maintenance password is used for the advanced management function of the device. Specifically, the high and low bits of the second hash value can be determined to sequentially and alternately select a preset number of character elements from the low bit to the high bit of the second hash value.

[0055] In addition, in some optional embodiments of the present invention, a password modification mechanism is established. When the user modifies the maintenance password, the user's initial password becomes invalid. In the operation of medical devices, this mechanism is particularly important. Because the operation of medical devices may involve medical staff at different levels, password modification can prevent those who have left their positions or had their permissions changed from using the old password for illegal operations. When the user modifies the maintenance password to be empty, the user's initial password is restored, which is convenient for medical staff to reuse the device in case of an emergency (such as when the device fails and needs to be quickly restored for emergency treatment). At the same time, the system will record the operation logs of password modification and restoration for security auditing.

[0056] In summary, in the method for generating a security password of a medical device in the above embodiments of the present invention, by using the unique code of the medical device and a custom preset character combination to generate a password, the strong correlation between the password and the medical device is ensured, and the password of each medical device is unique. It prevents unauthorized access to the medical device, protects the privacy data of patients and the key parameters of the device, and greatly improves the security of the medical device. The user initial password and the maintenance-level password are generated separately, meeting the security requirements of different management levels of the medical device. Medical staff use the user initial password for daily operations, while device maintenance staff use the maintenance password for advanced management operations such as device repair and upgrade, avoiding password permission confusion. It solves the problems of low security and easy permission confusion in the existing methods for generating passwords of medical devices.

[0057] Embodiment 2

[0058] This embodiment also proposes a method for generating a security password of a medical device. The difference between the method for generating a security password of the medical device in this embodiment and the method for generating a security password of the medical device in Embodiment 1 is as follows:

[0059] Before the step of selecting a preset number of character elements from the first hash value according to the first preset selection rule, the following steps are further included:

[0060] Collect the timestamp when obtaining the unique identification code of the medical device for which the password is to be allocated, and perform a hash operation on the timestamp to obtain a time key regarding the acquisition time;

[0061] Respectively obtain the digital elements in the time key, and sum the digital elements to obtain the corresponding key value;

[0062] Obtain the sequence length of the first hash value or the second hash value, perform a modulo operation on the sequence length using the key value to obtain the corresponding position value, and use the position value to determine the starting extraction position of the character elements in the first hash value and the second hash value.

[0063] First, collect the timestamp when obtaining the unique identification code of the medical device for which the password is to be assigned. This timestamp records the exact time of obtaining the identification code. Then, perform a hash operation on this timestamp to obtain a time key regarding the acquisition time. Next, respectively obtain the digital elements in the time key. These digital elements are the decimal digits in the time key. Perform a summation operation on these digital elements to obtain a corresponding key value. This key value is a simplified representation based on the result of the timestamp hash operation. Next, obtain the sequence length of the first hash value or the second hash value. Use the previously calculated key value to perform a modulo operation on the sequence length to obtain a corresponding position value. This position value is used to determine the starting extraction position of the character elements in the first hash value and the second hash value. For example, if the result of the modulo operation is 3, it is determined that the third digit from the high position of the first hash value is the starting extraction position of the character elements in the first hash value. Using the dynamic element timestamp to dynamically determine the starting extraction position further improves the security of subsequent password generation.

[0064] Further, after determining the starting extraction position of the character elements, the character elements in the first hash value and the second hash value can be respectively extracted based on a dynamic interval. Specifically, starting from the starting extraction position, extract the first character element from the first hash value or the second hash value, determine the numerical information corresponding to the first character element, perform a square operation on the digital information and then take the remainder of the sequence length to obtain the extraction interval for the next character element, and then extract the next character element until the extraction of the character elements is completed; among them, starting from the starting extraction position of the first hash value or the second hash value, extract the first character element. This character element is a hexadecimal character (such as '0' to '9' or 'a' to 'f'), and convert the extracted first character element into the corresponding numerical information. If the hash value is represented in hexadecimal, then the hexadecimal character needs to be converted into a decimal value. For example, the character 'a' corresponds to the value 10 in hexadecimal. The square operation multiplies the numerical information by itself. Divide the result of the square operation by the sequence length and take the remainder. This remainder will be used as the extraction interval for the next character element. According to the calculated extraction interval, starting from the next position of the first character element, skip the corresponding number of characters and then extract the next character element. Repeat the above steps, that is, continue to convert the currently extracted character element into numerical information, perform the square operation and the modulo operation, and then extract the next character element according to the new extraction interval until the extraction of the character elements is completed. Among them, the extraction interval for the next character element is dynamically determined through the square operation and the modulo operation, increasing the complexity of password generation and making it more difficult for attackers to predict or crack the password.

[0065] In summary, in the method for generating a security password for a medical device in the above embodiments of the present invention, by using the unique code of the medical device and a custom preset character combination to generate a password, the strong correlation between the password and the medical device is ensured, and the password for each medical device is unique. This prevents unauthorized access to the medical device, protects the privacy data of patients and the key parameters of the device, and greatly improves the security of the medical device. The user initial password and the maintenance-level password are generated separately, meeting the security requirements of different management levels of the medical device. Medical staff use the user initial password for daily operations, while device maintenance staff use the maintenance password for advanced management operations such as device repair and upgrade, avoiding password permission confusion. It solves the problems of low security and easy permission confusion in the existing methods for generating passwords for medical devices.
