Encryption design of mobile client data transmission

A two-way asymmetric protocol when logging in

1. The client initiates the asymmetric request first

2. The service side returns an asymmetric response

3. Return with request key and response key in return data

Symmetric key encryption can be used in the encryption of business data

4. The business data request is symmetric encrypted with the request key

5. Symmetric encryption with response key when responding to business data

Asymmetric encryption can use RSA, symmetric encryption can use DES
