‘n’ — Level UNICODE position character length ciphers for securing smart cards

In day to day life, Smart card plays an important role. Open your wallet! See at least 20 to 25 cards in it. Wondering?? Today, the world is fully in the hands of smart cards since it is easy to carry and even if it is stolen, it is secure. But due to the increase in hackers today, Smart cards are becoming insecure. The Encrypted PIN can be easily stolen by the cryptanalysts. So it is time to secure the Smart cards. In our previous paper, we have considered all the vulnerabilities of the Smart card and have provided various ways to overcome it. Still we feel that my algorithm is suffering from forgery attack. In this paper, we have applied a new encryption and a new hash algorithm to keep the information secure in Smart cards and to overcome forgery attack. The main advantage of this paper is, on an average, even the supercomputer will take 10¹⁰⁸⁴ years to decrypt, which is very much higher than the previous proposals.
