Mobile phone scrambler and its privacy communication method

Abstract

This invention relates to a mobile phone crypto suitable for realizing security voice and data communication of mobile communication network and PSTN including a handheld terminal set integrating a voice IO unit, a voice code and decode unit, a voice post process unit, a primary control unit, a supply management unit, a man-machine interface unit, a connection-expansion unit, a ciphere / de-ciphere unit and a security management unit, a special connection cable and special interface fittings. When a security communication is needed, the crypto of said mobile phone can cut in the mobile communication net or the PSTN quickly in the way of wire or wireless to ensure the security voice session or data communication by end to end and ciphering every time under the internal control of the crypto.

Problems solved by technology

[0002] With the continuous development of basic communication technologies such as mobile communication technology and public switching technology, the requirements for voice and data communication technology are also increasing. Security also puts forward higher and higher requirements. Although the mobile communication network and public switching network commonly used now can provide certain communication concealment, confidentiality and security, they only meet the basic needs of ordinary users or non-sensitive users. The use of security requirements requires higher and more reliable communication security measures for users involved in commercial-level or higher special fields, such as government, finance, military, public security, taxation, customs and other institutions or departments involved in the country. And for such users, they need to realize communication confidentiality in a wider geographical range and a wider range of various types of terminals. The current mobile communication network or public switching network voice security or confidentiality cannot meet the requirements of these users security level
