and the server verifies the identity bill information, when the verification is passed, online address book information is generated and encrypted by a secondary encryption algorithm and returned, the terminal acquires the encrypted online address book information, and the online address book information is decrypted by a secondary decryption algorithm reverse to the secondary encryption algorithm so as to be checked by a user of the terminal.
Preferably, the second encryption algorithm is encrypted by the following method:
(1) converting the source data into corresponding ASCII codes by using a specified code;
(2) rearranging the ASCII codes in the previous step regularly;
(3) using an encryption factor to convert the ASCII code obtained in the previous step to obtain an encrypted factor code;

Preferably, the specified code is a UTF-8 code.
Preferably, the identity ticket information includes: mobile phone number, public key, time period.
Preferably, the public key comprises a regularity rearrangement dimension and an encryption factor dimension.
Preferably, the call record information encrypted by the secondary encryption algorithm is generated when the verification is passed.
The invention adopts a secondary encryption algorithm, so that the transmission of the online address book information is safer and more reliable, is not easy to be cracked or monitored by a third party, and has extremely high security. Specifically, the following beneficial effects are achieved:
(1) the encryption speed is high, the normal data size can output the encryption result within 100 milliseconds, and if the data volume is small, the input of the encryption result is faster;
(2) recombining each character string ASCII code to ensure that the source number is chaotic;
(3) calculating by using the encryption factor, and determining that the encryption factor cannot be cracked under the condition of no encryption factor;
(4) and the BASE64 is used for secondary encryption to ensure the security of the data.

Detailed Description
In order that those skilled in the art can understand and implement the present invention, the following embodiments of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, a method for protecting online contact list information provided by the present invention includes:
step 10, the terminal generates identity bill information and requests a server to acquire online address book information;
and 20, the server verifies the identity bill information, when the verification is passed, online address book information is generated and encrypted by a secondary encryption algorithm and returned, the terminal acquires the encrypted online address book information, and the online address book information is decrypted by a secondary decryption algorithm reverse to the secondary encryption algorithm so as to be checked by a user where the terminal is located.
The secondary encryption algorithm is encrypted by adopting the following method:
(1) the source data is converted into corresponding ASCII code for each character using a specified encoding.
For example: the source data is abcdefg;
conversion to ASCII code is: 98,99,100,101,102,103,104.
(2) Recombining the corresponding ASCII codes according to the rule of half-and-half cross interchange positions;
for example: 98,99,100,101,102,103, 104;
as a result: 98 (1 st character), 104 (7 th character), 99 (2 nd character), 103 (6 th character), 100 (3 rd character), 102 (5 th character), 101 (4 th character);
(3) the previously recombined ASCII code is subjected to cryptographic calculations using a cryptographic factor (the preceding nomenclature being a conversion factor).
For example: 98,104,99,103,100,102,101
Results after encryption: 1552,1648,1568,1632,1584,1616,1600.
(4) And finally, performing secondary encryption by using BASE64 to ensure data security.
Encryption: BASE64(1552,1648,1568,1632,1584,1616,1600);
as a result:
MTU1MiwxNjQ4LDE1NjgsmMTYzMiwxNTgoLDE2MTYsMMTYwMA＝＝。
correspondingly, the decryption process is as follows:
(1) the encrypted data is decrypted by BASE 64:
for example:
MTU1MiwxNjQ4LDE1NjgsmMTYzMiwxNTgoLDE2MTYsMMTYwMA＝＝
as a result: 1552,1648,1568,1632,1584,1616,1600.
(2) And carrying out decryption calculation by using the encryption factor to obtain the ASCII code.
For example: 1552,1648,1568,1632,1584,1616,1600, respectively;
and (3) calculating the result: 98,104,99,103,100,102,101.
(3) According to the encryption rule, half-and-half cross exchange is carried out, and half-and-half exchange is carried out again to return to the original position.
For example: 98,104,99,103,100,102, 101;
as a result: 98,99,100,101,102,103,104.
(4) Inputting a result:
abcdefg。
in the foregoing, the identity ticket information includes: mobile phone number, public key, time period. The mobile phone number is the number of the current terminal or the associated terminal. The public key comprises a regularity rearrangement dimension and an encryption factor dimension. The regularity rearrangement dimension, for example, is the half-and-half cross exchange position; the encryption factor is a corresponding product multiplied by a number. And in the time period, the identity bill information is valid in the preset time, and if the time period is over, the identity bill information needs to be generated again. Accordingly, fig. 2 shows a communication flow chart based on the method of the present invention, which specifically includes the following processes:
(1) a terminal (for example, a mobile phone APP) initiates a request to acquire an online address list;
(2) the mobile phone APP locally generates an identity bill (information such as mobile phone number + public key + time) MD5 to generate a bill request to the server;
(3) the server (an online address book platform) verifies whether the bill passes or not, and if not, null data is returned;
(4) if the address list passes the encryption, generating an address list for encryption and returning;
(5) meanwhile, a call record data list is generated and encrypted to return;
(6) and the APP end of the mobile phone receives the data and decrypts the data by using the secret key to obtain the source data.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
