Abstract
The present invention discloses a method for clear session and scrambled session communication switch between mobile terminals comprising: a first terminal initiating a scrambled session switch control request to a second terminal, and the second terminal returning a scrambled session switch control response after receiving the scrambled session switch control request; and the first terminal initiating a key negotiation process with the second terminal after receiving the scrambled session switch control response returned by the second terminal, and then transferring to scrambled session communication or suspending the scrambled session communication with the second terminal; wherein the scrambled session switch control request includes a scrambled session request or a clear session request. The present invention further provides a system for clear session and scrambled session communication switch between mobile terminals comprising a scrambled session switch control module and an encryption module set in a mobile terminal. The present invention protects end-to-end security in the communication process of the mobile terminals effectively.
