In a preferred embodiment of the present invention, a digest one-way algorithm using MD5 is adopted in each of step S111, step S121, step S131, step S141, and step S151;
or/and adopting a summary one-way algorithm adopting SHA-1 in step S111, step S121, step S131, step S141 and step S151;

step S112, step S122, step S132, step S142 and step S152 are arranged in descending order;
or/and the steps S112, S122, S132, S142 and S152 are arranged in the descending order.
In a preferred embodiment of the present invention, step S2 includes:
the verification terminal performs the following operations on the received password:
Summary ValueC＝Hash Algorithm<C>，
wherein, the Hash Algorithm < > represents a digest one-way Algorithm which adopts one of MD5, SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512;
c represents a password received by the controller;
Summary ValueCthe password C received by the verification terminal is represented to be subjected to 1 time of password digest value obtained by adopting a digest one-way algorithm of one of MD5, SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512;
step S0 is further included before step S1, in which the verification terminal stores the obtained digest value of the preset password in the verification terminal, and the method for obtaining the preset password includes:
Summary Valuec＝Hash Algorithm<c>，
wherein, the Hash Algorithm < > represents a digest one-way Algorithm which adopts one of MD5, SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512;
c represents a password received by the authentication terminal in advance;
Summary Valuecthe password c received by the verification terminal in advance is represented to be subjected to 1 time of preset password digest value obtained by adopting digest one-way algorithm of one of MD5, SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512;
if the password abstract value calculated by the controller is consistent with a preset password abstract value preset in the verification terminal, the verification is successful;
if the password abstract value calculated by the controller is inconsistent with a preset password abstract value preset in the verification terminal, the verification fails. The transmission is safe, and the safety and the reliability are better.
One specific example is given below (all using MD5, which outputs a 16-bit 16-ary lowercase string):
if the user inputs the set password 023 on the verification terminal in advance, the controller executes the following operations:
Figure BDA0003006703480000141
it 4453d247e0117381 is stored in the authentication terminal.
Firstly, a controller receives a password input trigger signal, and a 1 st key, a 2 nd key, a 3 rd key, a 4 th key, a 5 th key, a 6 th key, a 7 th key, an 8 th key, a 9 th key and a 10 th key are respectively displayed for a button from top to bottom on a character input and display 3 from left to right; the method also comprises a delete button key and a confirm button key, wherein the delete button key is used for deleting the character with the input error and the confirm button key is used for inputting the trigger input completion signal; 10 characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 respectively; 0-9 is a digital character, and A characters can be digital characters (0-9), capital letter characters (A-Z) or lowercase letter characters (a-Z) independently, or one or any combination of the digital characters 0-9, one or any combination of the capital letter characters A-Z, or one or any combination of the capital letter characters A-Z or the lowercase letter characters a-Z or any combination thereof.
And a second step of performing the following operations:

in this embodiment, since 0 does not have a digest one-way algorithm, it is replaced with another character other than a, such as the lower case letter o.
