Encryption information step-by-step carries out xor operation, obtains the original KEY；
The step S6 is specifically included：The length for obtaining second encryption information expands the original KEY cyclic extensions
The length of original KEY afterwards is consistent with the length of the second encryption information, by the original KEY and described second after the expansion
Encryption information step-by-step carries out xor operation, obtains the mobile phone games data.
