Data ciphering and deciphering module and use thereof

Abstract

The invention discloses a data encrypting and decrypting module, which is characterized by comprising a central signal processing unit (MCU) and a secrecy chip which applies the reconfigurable logic technique, encrypting data which is inputted into the module by a communication local end, and transmitting the encrypted data to any specific communication device. The data encrypting and decrypting module at least comprises an interface for transmitting data, the data encrypting and decrypting module can decrypt the date which is received through a communication channel and has been encrypted by the other party, the data encrypting and decrypting module can widely used for paying for communication transmission devices, such as a payment device (POS machine), a fax machine, a fixed telephone, a mobile phone, Bluetooth and the like, and the module can allocate with corresponding structures, such as a modulator-demodulator and the like, according to different communication transmission devices, and can realize the encrypting and decrypting transmission of various data which need maintaining secrecy.

Description

technical field [0001] The invention belongs to the field of communication transmission equipment, and in particular relates to an encryption and decryption module that can be applied to various transmission media, transmit various information forms, has various interface processing capabilities, and can be applied to various communication equipment. Background technique [0002] After entering the 21st century, human society has entered the information age in an all-round way. The explosive development of informatization has brought about an unprecedented increase in social efficiency, but at the same time, it has also introduced the struggle or competition between different countries, different interest groups, and even individuals into the information field. Information security is related to the interests of all countries, groups, and individuals, and even life and death. The weak link of information security is the transmission process of information. This is because ...
