SECURE MOBILE COMMUNICATION

Background

With the rapid development of society and the rising of communication technology, the mobile phone has played a more and more indispensable role in our daily life. People’s daily work, even government and commercial affairs are completed through mobile phone short messages and voice calls, which contain lots of sensitive, private and important business information, even include some important information related to the state affairs and political events. Therefore, how to guarantee the confidentiality of SMS and voice contents has always been an important research subject.
It is required to encrypt both sides of the phone calls and SMS by technical methods. The mobile end-to-end security protection ability can be significantly improved through data encryption protection.


 

Introduction

In order to ensure the information security of mobile communications and meet both domestic and overseas security needs, Beijing CS&S-TH Technology Co. Ltd (Hereinafter as CS&S-TH) has integrated voice channel encryption technology which has independent intellectual property rights into encrypted mobile phones, and combined mobile communications safeguards and system security design techniques, we have developed commercial encrypted GSM mobile phone with large-scale popularization and application.Tthe encrypted GSM mobile phone not only have common features like ordinary mobile phones, but also can make all-round encryption for voice and SMS messages, and be able to realize “anti-wiretapping, anti-leak, anti-loss, anti-virus”, which can fully guarantee the mobile communication security for users.

Anti-wiretapping
• All-round encryption for voice and SMS messages
• Domestic customization system, no Trojan risk
• Encryption algorithm approved by the national authorities
Anti-leak
• No camera, Bluetooth or Internet access
• Encrypted storage for important information
• Password access control (10-16 bits)
Anti-loss
• SIM card-bound, data will be automatically destroyed after illegally change the card
• Security Management System will remotely ruin the lost phone's internal data.
• Manual destruction for emergency
 

Features

GSM without replacing SIM card
The encrypted GSM mobile phone can be used without replacing SIM card or opening any business. And you can roam to all regions and countries covered with GSM networks.
Initiation in China with international leading level 
The encrypted GSM mobile phone applied the first developed speech-like modulation technology which has independent intellectual property rights. At present, no other encrypted mobile phone manufacturers can implement this technology.
Integration design based on customization system
The customization non-open operating system is applied. And the design has security module and communications module, which are convenient for the user to carry and operate, and it can prevent threats such as viruses and Trojan as well.
