Abstract
A method for dynamic encryption and signing includes: obtaining, by a terminal during session connection, a predetermined first key index and a randomly-generated first signature index; signing session request data with a first signature corresponding to the first signature index; encrypting the session request data with a first key corresponding to the first key index; sending the encrypted session request data and the first signature index to the server; and receiving, from the server, session response data signed with a second signature corresponding to a second signature index and encrypted with a second key corresponding to a second key index, after decryption and signature verification by the server over the session request data succeed. The second signature index and the second key index are randomly selected by the server and saved in a login session object accessible by both the server and the terminal.
