[0010] Furthermore, in the above-mentioned method for generating a security password for a medical device, the step of selecting a preset number of character elements from the first hash value according to a first preset selection rule and using the character elements to form the user's initial password for the medical device comprises: If the character length of the extracted character element does not meet the length of the user's initial password, it is padded with custom characters until the length of the user's initial password is met.

[0018] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below 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, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Embodiment 1 See also Figure 1 , shown is a method for generating a security password for a medical device in a first embodiment of the present invention, the method comprising steps S10 to S12.

[0023] Step S10, obtaining a unique identification code of the medical device to which a password is to be assigned, combining the unique identification code with a first preset character and generating a first hash value through a preset hash algorithm.

[0024] Among them, the unique identification code of medical equipment is the unique identifier assigned to the medical equipment during the production process. For medical equipment, the unique identification code can be obtained by reading the hardware code on the device's mainboard through the device's built-in chip reader, or 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 medical equipment to ensure their uniqueness and accuracy.

[0025] The unique identification code of the medical device is combined with a first custom preset character, and a first hash value is generated by a preset hash algorithm, wherein the first preset character can be a fixed string, or some other preset, specific characters; specifically, in the embodiment of the present invention, the MD5 algorithm can be used to calculate and generate a unique first hash value. The MD5 algorithm is selected because it has a fast calculation speed and can meet the real-time requirements for the secure password generation of the device. By combining the identification code of the medical device with the first custom preset character, the security of the password generation is greatly improved.

[0026] Step S11, selecting a preset number of character elements from the first hash value according to a first preset selection rule, and using the character elements to form an initial user password of the medical device; 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, such as selecting the first n characters in the first hash value, selecting one every m characters, or selecting characters at a specific position, etc. Specifically, in an embodiment of the present invention, the first preset selection rule selects characters based on a specific order. During the specific implementation, the high and low bits of the first hash value are determined to select a preset number of character elements from the high bit to the low bit of the first hash value in sequence. Finally, the selected character elements are combined in the selection order or other predefined order to form the user's initial password for the medical device. The password is used for the login operation of medical staff. In addition, if the character length of the extracted character element does not meet the length of the user's initial password, it is filled with custom characters until the length of the user's initial password is met.

[0027] Step S12, combining the first hash value with the second preset character to generate a second hash value through a preset hash algorithm, and then using a second preset selection rule to select a preset number of character elements from the second hash value to form a maintenance password for the medical device.

[0028] 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 a second preset selection rule to form a maintenance password. The second preset selection rule is different from the first preset selection rule. Exemplarily, the second preset selection rule also selects character elements according to a preset selection order, but is different from the first preset selection rule, so as to achieve the separation of the user's initial password and the maintenance password. The maintenance password is used for advanced management functions of the device. Specifically, the high and low bits of the second hash value can be determined to select a preset number of character elements from the low bit to the high bit of the second hash value in sequence.

[0029] In addition, in some optional embodiments of the present invention, a password modification mechanism is established, and when the user modifies the maintenance password, the user's initial password becomes invalid. This mechanism is particularly important in the operation of medical equipment. Because the operation of medical equipment may involve medical staff of different levels, password modification can prevent personnel who have resigned or whose authority has changed from using old passwords to perform illegal operations. When the user changes the maintenance password to empty, the user's initial password is restored, which makes it convenient for medical staff to reuse the equipment when the medical equipment encounters an emergency (such as when the equipment fails and needs to be quickly restored for emergency treatment). At the same time, the system will record the operation log of password modification and restoration for security auditing.

[0030] In summary, the method for generating a secure password for a medical device in the above embodiment of the present invention generates a password by combining the unique code of the medical device with a customized preset character, thereby ensuring a strong correlation between the password and the medical device, and the password of each medical device is unique. It prevents medical devices from being accessed by unauthorized personnel, protects the patient's privacy data and key parameters of the device, and greatly improves the security of the medical device. The user's initial password and the maintenance-level password are generated separately, meeting the security requirements of different management levels of medical devices. Medical staff use the user's initial password for daily operations, while equipment maintenance personnel use the maintenance password for advanced management operations such as equipment maintenance and upgrades, avoiding confusion in password permissions. It solves the problem of low security and easy confusion in permissions in the method of generating passwords for medical devices in the prior art.

[0031] Embodiment 2 This embodiment also proposes a method for generating a security password for a medical device. The difference between the method for generating a security password for a medical device in this embodiment and the method for generating a security password for a medical device in the first embodiment is that: Before the step of selecting a preset number of character elements from the first Hash value according to the first preset selection rule, the step further includes: Collecting the timestamp when the unique identification code of the medical device to be assigned a password is obtained, and performing a hash operation on the timestamp to obtain a time key related to the acquisition time; Get the digital elements in the time key respectively, and sum the digital elements to get the corresponding key value; Obtain the sequence length of the first hash value or the second hash value, perform a modulo operation on the sequence length using the secret key value to obtain a 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.

[0032] First, collect the timestamp when the unique identification code of the medical device to be assigned a password is obtained. This timestamp records the exact time when the identification code is obtained. Then, perform a hash operation on this timestamp to obtain a time key about the acquisition time. Then, obtain the digital elements in the time key respectively, which are decimal numbers in the time key. Perform a sum operation on these digital elements to obtain a corresponding key value, which 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. Perform a modulus operation on the sequence length using the previously calculated key value to obtain a corresponding position value. This position value is used to determine the starting extraction position of the character element in the first hash value and the second hash value. For example, if the result of the modulus operation is 3, the third bit of the first hash value from the high bit is determined to be the starting extraction position of the character element in the first hash value. The dynamic element timestamp is used to dynamically determine the starting extraction position, further improving the security of subsequent password generation.

[0033] Further, after determining the starting extraction position of the character element, the character elements in the first hash value and the second hash value can be extracted based on the dynamic interval. Specifically, the first character element is extracted from the first hash value or the second hash value according to the starting extraction position, the numerical information corresponding to the first character element is determined, and the next character element is extracted after the extraction interval of the next character element is obtained by square operation of the digital information and the remainder sequence length is obtained, until the character element extraction is completed; wherein, starting from the starting extraction position of the first hash value or the second hash value, the first character element is extracted. This character element is a hexadecimal character (such as "0" to "9" or "a" to "f"), and the extracted first character element is converted into the corresponding numerical information. If the hash value is expressed 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, and the square operation is to multiply 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. Based on the calculated extraction interval, starting from the next position of the first character element, after skipping the corresponding number of characters, the next character element will be extracted and the above steps will be repeated, i.e., the currently extracted character element will continue to be converted into numerical information, and square and remainder operations will be performed. Then, the next character element will be extracted based on the new extraction interval until the character element extraction is completed. The extraction interval for the next character element is dynamically determined through square and remainder operations, which increases the complexity of password generation and makes it more difficult for attackers to predict or crack the password.

[0034] In summary, the method for generating a secure password for a medical device in the above embodiment of the present invention generates a password by combining the unique code of the medical device with a customized preset character, thereby ensuring a strong correlation between the password and the medical device, and the password of each medical device is unique. It prevents medical devices from being accessed by unauthorized personnel, protects the patient's privacy data and key parameters of the device, and greatly improves the security of the medical device. The user's initial password and the maintenance-level password are generated separately, meeting the security requirements of different management levels of medical devices. Medical staff use the user's initial password for daily operations, while equipment maintenance personnel use the maintenance password for advanced management operations such as equipment maintenance and upgrades, avoiding confusion in password permissions. It solves the problem of low security and easy confusion in permissions in the method of generating passwords for medical devices in the prior art.
