The design of the mobile phone module information encryption system based on FPGA

Today's society is more and more tends to the development of information technology and the popularity of mobile phones also makes personal information security issues concerned. The security transmission of mobile phone text messaging is particularly important. This article mainly designs a hardware encryption system based on GSM FPGA module and uses RSA public key encryption algorithm and implements the design of SMS encryption system. Currently RSA public encryption algorithm has become the most important password, which making up the RSA encryption algorithm slowly and exerting vital advantage of the large space of RSA algorithm key because of the speediness of hardware encryption, excellent reliability and good stability. Experiments show that FPGA-based RSA encryption system of this article proposing can guarantee the secure transmission of information and enhance the security of SMS transmission.
