Privacy and trust in wireless networks have attracted plenty of attention in the information age. Various types of high-complexity encrypt algorithms are exploited for improving the security of the communication, such as providing security in global system for mobile (GSM) communication cell phones. This paper proposes a new algorithm, which combines the Vigenère cipher, linear feedback shift register (LFSR) and one-time pad (OTP) together to reduce the computational complexity and improve the system security. Benefitting from the combination of these advantages, our proposed algorithm makes and attack process more complicated. Particularly, when the Vigenère cipher is expanded to including alphabets, symbols and numbers, it will become safer and more difficult to break just by using frequency or brute force methods, etc. The alphabet entropies of plain and cipher texts are calculated and compared. In addition, the cipher text space is further expanded. The numerical results, obtained through Java programming language, illustrate that the proposed cryptosystem is safer than the conventional Vigenère cipher.
