Step 1.3, according to described deciphering QR code 0-1 row vector D'=[d 1, d 2..., d w..., d w], obtain the 1st deciphering cellular state value of described S Wolffram invertible element cellular automaton 2nd dimension deciphering born of the same parents state value B 2 = [ d W 2 + 1 , d W 2 + 2 , · · · , d W ] ;
Step 2, initialization
Utilize rotation function to described encryption evolution rule sequence R en={ r 1, r 2..., r kand encryption evolution time Number Sequence I en={ N 1, N 2..., N kprocess respectively, obtain deciphering evolution rule sequence R de={ r k, r k-1..., r 1and deciphering evolution time Number Sequence I de={ N k, N k-1..., N 1;
Step 3, decipher described car plate trade mark information ciphertext character string s'
Step 3.1, definition loop variable y; The y time deciphering cellular state value B ywith the y+1 time deciphering cellular state value B y+1; 1≤y≤K; And initialization y=1;
Step 3.2, by described the y time deciphering cellular state value B ywith the y+1 time deciphering cellular state value B y+1as the y time deciphering initial condition value of described SWolffram invertible element cellular automaton;
Step 3.3, from described deciphering evolution rule sequence R dein choose y evolution rule r k+1-yn is carried out to described the y time initial condition value k+1-ysecondary evolution, obtains the y+2 time deciphering cellular state value B y+2;
Step 3.4, judge whether y+1 exceeds threshold k; If so, then exit execution, thus obtain the K+2 time deciphering cellular state value B of invertible element cellular automaton k+2; Otherwise, value y+1 is assigned to y, and returns step 3.2 and perform;
Step 3.5, the decoding of described QR Quick Response Code rule is utilized to decipher cellular state value B to the K+2 time of described invertible element cellular automaton k+2decode, thus obtain described car plate trade mark information character string s.
