A smart phone secure communication system and method

Abstract

The invention belongs to the technical field of information safety, in particular to secrete communication of a smart phone. According to the technical scheme, a secrete communication system for the smart phone comprises a communication management platform (1), a main control service system (3) and a plurality of secrete mobile phones (3). Compared with the technology and method for the other secrete mobile phones, the secrete communication system and method use an encryption crushing technology and a recombination decryption technology to transmit complete communication information through x mobile communication signal channels, and each mobile communication signal path transmits one part of cipher-text fragments of a voice data unit or a short message; people cannot restore the complete cipher-text not to mention the plain text of the voice or the plain text of the short message through eavesdropping any one of the mobile communication signal channels, and therefore, the illegal eavesdropping on the mobile communication network is effectively avoided; the voice data or short message encryption, decryption and crushing recombination are performed in a customized SD key in the secrete mobile phone, and the rogue program eavesdropping to the secrete mobile phone terminal can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to secure communication of smart phones. Background technique [0002] Because it is not limited by regions and communication cables, mobile communication networks are widely used. However, the wireless channel is an open channel. While giving wireless users the freedom to communicate, it also brings some unsafe factors to the wireless communication network, such as wireless eavesdropping, identity forgery, data tampering, and post-denial of service. In current mobile phone applications, in addition to ordinary communication, many confidential and sensitive information are not allowed or dare not be communicated by mobile phone communication, such as public security, business secrets, intellectual property rights, finance, and even government, diplomatic and military intelligence The disclosure or illegal wiretapping of such information may bring major or e...

Problems solved by technology

However, the wireless channel is an open channel. While giving wireless users the freedom to communicate, it also brings some unsafe factors to the wireless communication network, such as wireless eavesdropping, identity counterfeiting, tampering with data, and post-service denial.

In current mobile phone applications, in addition to ordinary communication, many confidential and sensitive information are not allowed or dare not be communicated by mobile phone communication, such as public security, business secrets, intellectual property rights, finance, and even government, diplomatic and military intelligence and other information, the leakage or illegal wiretapping of such information may bring significant or even catastrophic losses to the country and relevant units

[0003] In order to enhance the security of the mobile communication network, the 2G GSM / GPRS mobile network provides encrypted protection for the wireless communication between the mobile phone and the base station (air interface) on the communication link, but the communication content in the core (wired) network is still encrypted. It is transmitted in plain text, which makes the communication between mobile users vulnerable to illegal eavesdropping on the core network; although 3G has realized two-way authentication between the mobile communication network and mobile users, there is no digital signature at the user end, which still cannot solve the problem. Denial, forgery, tampering, and impersonation, etc., have the possibility of network attacks; and 4G is an IP-based network that integrates radio and television networks, wireless cellular networks, satellite networks, wireless local area networks, and inherent wired networks. The new generation of mobile communication networks is facing greater security threats

[0004] Therefore, although mobile phones and mobile communication networks provide people with convenient and fast communication methods, in some occasions with high security requirements, the scope of application of mobile phones is greatly limited.
