Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
One embodiment of the present of invention purpose is as the key opening automobile by the mode of random dictionary and random coded, as automobile lend other people use time, it is possible to this key is sent to by means of car person in the way of SMS.No matter it is owner or pre-authorization person, the right to use of automobile can be obtained according to key.
To achieve these goals, the concrete technical scheme of the present invention is: choose the process with random coded by what system carried out random dictionary, make the information one_to_one corresponding on user and automobile, when user inputs Chinese character string with correct order on onboard system, certification success, otherwise authentification failure.Wherein random dictionary refers to the process randomly drawing a dictionary table from dictionary library.Random coded refers to that the certain mode of use rearranges associated order.The workflow block diagram of vehicle remote Verification System is as shown in Figure 1.
S11 automotive vehicle owner starts remote authentication system when leaving automobile.
S12 is when car owner or kith and kin need to use automobile, and car owner sends application instruction by mobile phone terminal.
S13 onboard system communication module starts random dictionary generation module after receiving dependent instruction, generates random dictionary, and randomly draws a random dictionary.
S14 onboard system, according to the S13 random dictionary generated, generates a string random order code.
Random dictionary is sent to car owner's mobile phone terminal by S15 onboard system with random order code.As kith and kin borrow car, this message can be forwarded to kith and kin's mobile phone by car owner.
S16 associated user is according to random dictionary, according to the order of random order code defined, clicks required Chinese character on mobile unit.
S17 is as correct in inputted, and completes certification, and automobile mandate is complete.Such as input error 3 times, automobile locking.
Wherein the product process mode of random dictionary is as in figure 2 it is shown, specifically comprise the following steps that
S21 chooses n*p Chinese characters in common use from Hanzi font library.
Above-mentioned Chinese character is carried out decimal code by S22 in order.
Decimal code corresponding for this each word is carried out binary coding by S23, and sets up one-to-one relationship with Chinese character.
Every p the Chinese character of S24 forms a group in order, randomly draws a Chinese character for each group after packet, altogether extracts n Chinese character and stores according to original order, after all groups of Chinese characters extract, defines p dictionary, forms dictionary library.
The flow process that random order code produces is as it is shown on figure 3, specifically comprise the following steps that
S31 extracts the dictionary containing n Chinese character that random dictionary generation step selects.
N the Chinese character that S31 is produced by S32 carries out random order to be upset, and produces random order code.
The order arrangement that the binary coding code in order of the Chinese character that random order code that S32 is produced by S33 is corresponding is specified.
The S33 code stream produced is carried out Run-Length Coding and transmits by S34.
Vehicle-mounted interactive device inputs: onboard system is transferred to vehicle-mounted interactive device after generating code stream, this equipment dictionary that correspondence system produces after being decoded by the distance of swimming forms Chinese character string, system adds the Chinese character in k other not selected dictionaries at random, is shown to user for you to choose.
