Problems solved by technology

For the packet domain network of mobile communication, because the mobile terminal will often switch to different base stations, the link will be interrupted
In addition, the power of mobile terminals is generally limited. If you use the long connection method in the TCP protocol to communicate with the server, the power consumption of mobile terminals will increase sharply, which will affect the user experience.

Abstract

The invention provides a safety channel establishment method, and a data protection method and a safety channel key updating method thereof. When executing the establishment of handshake flow of the safety communication channel, a terminal and a server side check whether the safety communication channel is successfully established and a key is unchanged, and checks whether the certificate of the opposite side is cached; if related data is cached, the transmitted data and flow during the handshake flow of the two parties can be reduced, so that the purposes of shortening the time for establishing the safety communication channel for the two parties aiming at the packet domain communication characteristic of a mobile communication network and under the conditions of ensuring the data safety during the data communication of the terminal and the server side can be achieved, and the purpose of having no need of always maintaining TCP chain between the two communication parties can be achieved.

Description

technical field [0001] The invention relates to a method for establishing a safe channel, a method for protecting data thereof, and a method for updating a secret key of the safe channel, in particular to a method for establishing a safe channel for mobile communications, a method for protecting data therefor, and a method for updating a secret key of the safe channel. Background technique [0002] A very common secure communication channel establishment and data protection method is to use the Transport Layer Security protocol (TLS), which is used to provide confidentiality and data integrity between two communication terminals based on the characteristics of digital certificates. The TLS protocol (RFC2246 RFC4346) is between the TCP / IP protocol and various application layer protocols, providing security support for data communication. [0003] TLS Handshake Protocol (TLS Handshake Protocol), based on the TLS record protocol, is used for initial negotiation functions such a...
