specific Embodiment

[0102] A commercial-level encrypted voice communication service system made by a communication operator based on the present invention. Through custom-made special mobile terminals with built-in security encryption chips certified by the State Secret Bureau, and using commercial encryption technology and information security technology, we provide customers with commercial-grade end-to-end mobile phone voice communication encryption functions to prevent eavesdropping.

[0103] By implementing the technical solution of the present invention, the following technical effects are achieved.

[0104] 1. National commercial secret level certification, voice encryption is more secure. It adopts high-strength encryption algorithms such as sm1 stream encryption and decryption algorithm and sm2 asymmetric algorithm.

[0105] 2. End-to-end full encryption, one encryption per call is more secure; end-to-end full ciphertext transmission, random key, one key per call.

[0106] 3. Realize e...

Abstract

The invention discloses a secure communication method and system based on a P2P mode. The method comprises the following steps of separating P2P communication data and common traffic data; making a request for an encryption public key of a P2P communication opposite terminal client to a security capability center; generating a random key and encrypting and sending the random key to P2P communication data of the opposite terminal client; utilizing the encryption public key of the opposite terminal client to encrypt the random key; utilizing a signature private key of a local client to sign composite data, wherein the composite data includes the encrypted P2P communication data and the random key; and sending the signed composite data to the opposite terminal client. Through the scheme, the secure point-to-point communication between users can be provided.

Description

technical field [0001] The invention relates to the field of information security, in particular to a P2P mode-based secure communication method and system. Background technique [0002] In the era of "Internet +", the development of mobile Internet is deepening. Mobile smart terminals are not only communication and entertainment tools, but also promote the rapid development of mobile government affairs, mobile law enforcement, mobile office and mobile e-commerce. [0003] As the mobile operating system with the highest market share in smartphones, Android has a huge user base of hundreds of millions. However, due to its open source code, the prevalence of system vulnerabilities is beyond imagination. Mobile terminal information security incidents occur frequently, and information security has become the focus of social attention. [0004] The traditional way to protect personal information security on Android phones is to try to avoid browsing sensitive websites and instal...
