Abstract
The invention discloses a password input method, relates to the technical field of automobile encryption, and solves the technical problem of low encryption strength of the existing automobile, and the method comprises the following steps: setting a password write-in scheduling module in communication connection with an operating system; setting a write-in password module for receiving the number input by a keyboard or the number sent by a CAN bus; setting a mapping module, wherein the mapping module stores a mapping table in which numbers and characters are in one-to-one correspondence; setting a password storage module for storing passwords; the writing password module sends the received number to the mapping module, and the mapping module judges whether the received number is valid; if the number is valid, the mapping module queries the mapping table according to the received number to obtain a corresponding character and sends the character to the password writing scheduling module, and the password writing scheduling module sends the received character to the operating system and the password storage module; otherwise, the mapping module sends out error information to remind the user to input the numbers again.
Description
Technical Field
The invention relates to the technical field of automobile encryption, in particular to a password input method.
Background
In the field of industrial control or automotive electronics, there are times when it is necessary to enter a letter-type password, such as ABC, or a symbol-type password, such as + -, for strengthening the password strength. However, in some specific situations, such as the car CAN bus network, no keyboard or physical keys exist, or only a numeric keyboard is equipped for cost reduction without a full-size keyboard, so that letters or symbols cannot be obtained, and the password strength is greatly reduced.
Disclosure of Invention
The present invention is directed to solve the above-mentioned deficiencies of the prior art, and an object of the present invention is to provide a method for inputting a password, which can improve the password strength.
The technical scheme of the invention is as follows: a method of inputting a password, comprising:
setting a password write-in scheduling module in communication connection with an operating system;
setting a write-in password module for receiving the number input by a keyboard or the number sent by a CAN bus;
setting a mapping module, wherein the mapping module stores a mapping table in which numbers and characters are in one-to-one correspondence;
setting a password storage module for storing passwords;
the writing password module sends the received number to the mapping module, and the mapping module judges whether the received number is valid; if the number is valid, the mapping module queries the mapping table according to the received number to obtain a corresponding character, and sends the character to the password writing scheduling module, and the password writing scheduling module sends the received character to the operating system and the password storage module; otherwise, the mapping module sends out error information to remind the user to input the numbers again.
As a further improvement, the keyboard is a numeric keyboard.
Further, the CAN bus is connected to a terminal or a contact switch for transmitting binary information through a connector.
Further, the correspondence between the numbers and the characters is the correspondence between the numbers and the characters in the ASCII code.
Further, if the mapping module determines that the received number is valid, the mapping module feeds back the character corresponding to the number to the user.
Advantageous effects
Compared with the prior art, the invention has the advantages that: the invention can effectively input all characters in the ASCII code by inquiring the input number into the mapping table to obtain the corresponding characters, thereby greatly improving the password strength.
Drawings
FIG. 1 is a frame diagram of the present invention;
FIG. 2 is a flow chart of the present invention.
Detailed Description
The invention will be further described with reference to specific embodiments shown in the drawings.
Referring to fig. 1 and 2, a password input method includes:
setting a password write-in scheduling module in communication connection with an operating system of the automobile;
setting a write-in password module for receiving the number input by a keyboard or the number sent by a CAN bus;
setting a mapping module, wherein the mapping module stores a mapping table in which numbers and characters are in one-to-one correspondence;
setting a password storage module for storing passwords;
the writing password module sends the received number to the mapping module, and the mapping module judges whether the received number is valid, namely whether the number is in a number range in the mapping table; if the number is valid, the mapping module queries the mapping table according to the received number to obtain a corresponding character and sends the character to the password writing scheduling module, and the password writing scheduling module sends the received character to the operating system and the password storage module; otherwise, the mapping module sends out error information to remind the user to input the numbers again.
In this embodiment, the keyboard is a numeric keypad. The CAN bus is connected to the terminals or to the contact switches for sending binary information via the connections. The terminal can input numbers in various formats, such as binary, octal, decimal and hexadecimal, and the contact switch can input binary numbers. The correspondence between numbers and characters is the correspondence between numbers and characters in ASCII code, as shown in table 1 below. If the bus sends hexadecimal 0x41, then translated to "A", and sends hexadecimal 0x43, then translated to "C", if a numeric keypad is used, it may end up with # as a single character, e.g., input 101 #.
TABLE 1
If the mapping module judges that the received number is valid, the mapping module feeds back the character corresponding to the number to the user, so that the user can confirm whether the input password is the specified password. The information can be fed back or error information can be sent out through a display screen or a loudspeaker.
The password storage module compares the received password with the stored password, if the comparison is successful, the password write-in scheduling module sends success information to the operating system, and if the comparison is failed, the password write-in scheduling module sends failure information to the operating system. If the password storage module does not store the password, the received password is directly stored, and the password is written into the scheduling module to send success information to the operating system. If the password is modified, the received password is used for replacing the stored password.
The invention can effectively input all characters in the ASCII code by inquiring the input number into the mapping table to obtain the corresponding characters, thereby greatly improving the password strength.
The above is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that several variations and modifications can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
