Embodiment Construction

[0031] Functional Overview

[0032] The main idea of ​​the present invention is: in combination with the security measures provided by WAPI at the bottom layer, using the digital signature algorithm and WAPI security framework that adopts the public key infrastructure, and utilizing the elliptic curve encryption method provided by WAPI to realize the signature of the instant message, so that both parties in the communication The invention provides a technical scheme of identity authentication, tamper-proof and non-repudiation secure instant message communication.

[0033] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. If there is no conflict, the embodiments of the present invention and the features in the embodiments ca...

Abstract

The invention discloses a transmission method, a system and a WAPI terminal for instant messages; wherein the method comprises: after a first WAPI terminal and a second WAPI terminal are accessed to an IMS core network, the first WAPI terminal carries out Hash operation to the sent instant message to get a first operation result; the first WAPI terminal uses a private key and elliptic curve cryptographic algorithm to encrypt the first operation result to obtain a second operation result; the first WAPI terminal sends the unencrypted instant messages and the second operation result to the second WAPI terminal. The adoption of the invention can provide an anti-tamper, non-repudiation and safe instant message communication mechanism.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and system for transmitting instant messages and a WAPI terminal. Background technique [0002] The Wired Equivalent Privacy (WEP) security mechanism originally used in the Wireless Local Area Network (WLAN) has been proven not to have the same security as wired, which has brought huge challenges to the WLAN. security risks. [0003] In the process of formulating the WLAN national standard in my country, the WLAN Authentication Privacy Infrastructure (WAPI for short) mechanism is used to replace the IEEE 802.11 security scheme. WAPI uses the Elliptic Curve Diffie-Hellman key agreement protocol (Elliptic Curve Diffie-Hellman, referred to as ECDH) of the public key system to realize the verification and session key of the terminal certificate and the access point (AccessPoint, referred to as AP) certificate negotiation. WAPI ensures the confidential data transmissio...
