Further Research on Registration System with Vandermonde Matrix
We propose an improved software registration system from our previous research. Our improvements are mainly as follows. (1) Changing basic field to make the scheme suitable for all characters. (2) Changing encryption and decryption formulae to make the scheme more complex. (3) Using the technique of letter decomposition and composition to make the scheme more deceptive to a possible adversary. (4) Using mobile phone in the system to enhance the security. Experimental results and analysis show that the improvement is successful and the scheme is viable and secure.
