Method and Apparatus for Managing Application Identifier

A method for managing an application identifier, comprising:

• receiving, by a terminal, a first string from an identifier management apparatus, wherein the first string is in an encrypted state;
• decrypting, by the terminal, the first string according to a private key of a user to acquire a second string and a private key of the application identifier from the first string, wherein the second string is a feature identifier obtained by hash processing;
• joining, by the terminal, the application identifier and the second string to obtain a public key of the application identifier;
• and
• verifying, by the terminal, validity of the private key of the application identifier according to the public key of the application identifier.

An apparatus for managing an application identifier, comprising:

• a memory comprising instructions;
• a receiver configured to receive a request from a terminal to apply for a private key of the application identifier;
• a processor coupled to the memory and the receiver, wherein the instructions cause the processor to be configured to:
• acquire a user identifier and the application identifier according to the request;
• acquire a feature identifier of the user according to the user identifier;
• and
• generate a private key of the application identifier according to the application identifier and the feature identifier of the user;
• and
• a transmitter coupled to the processor and configured to send the private key of the application identifier to the terminal.

A terminal, comprising:

• a memory comprising instructions;
• a receiver configured to receive a first string from an identifier management apparatus, wherein the first string is in an encrypted state;
• and
• a processor coupled to the memory and the receiver, wherein the instructions cause the processor to be configured to:
• decrypt the first string according to a private key of a user to acquire a second string and a private key of an application identifier from the first string, wherein the second string is a feature identifier obtained by hash processing;
• join the application identifier and the second string to obtain a public key of the application identifier;
• and
• verify validity of the private key of the application identifier according to the public key of the application identifier.
