(The security of the one-time pad is only as secure as the security of the one-time pad key-exchange).
it requires perfectly random one-time pads, which is a non-trivial software requirement.International Journal of Embedded Systems, 2018 Vol.10 No.3, pp.Despite Shannon's proof of its security, the one-time pad has serious drawbacks in practice: Keywords: Vigenère cipher encryption decryption linear feedback shift register LFSR. The numerical results, obtained through Java programming language, illustrate that the proposed cryptosystem is safer than the conventional Vigenère cipher. In addition, the cipher text space is further expanded. The alphabet entropies of plain and cipher texts are calculated and compared. 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. Benefitting from the combination of these advantages, our proposed algorithm makes and attack process more complicated. 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. 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.
