DATA-ENCRYPTING METHOD AND DECRYPTING METHOD FOR A MOBILE PHONE |
摘要 |
Disclosed is a cell phone data encryption method, which comprises the steps of obtaining a PIN code which is input by a user, obtaining a SIM card code from a SIM card according to the PIN code, and combining the PIN code with the SIM card code to form a password string; and encryption source data using the password string, so as to obtain encrypted data. Also provided is a cell phone data encryption method. Through the manner mentioned above, the technical solution provided in the present invention can protect cell phone data. |

1. A data-encrypting method for a mobile phone, comprising:
obtaining a PIN code input by a user and obtaining an SIM card code from an SIM card according to the PIN code, and combining the PIN code and the SIM card code into a password string; using the password string to encrypt source data so as to obtain encrypted data; and setting an encrypted-data identification (ID) code by using an IMEI number of the mobile phone, and putting the encrypted-data ID code before the encrypted data; wherein the step of using the password string to encrypt source data so as to obtain encrypted data comprises: reading the source data in units of a number of bytes of the password string; performing a logic operation on the password string and the source data that is read; and storing the source data, which has been performed the logic operation on, as the encrypted data; wherein the logic operation is an XOR operation. |
