In this paper, we proposed a visual cryptography for one-time password web authentication. Traditional web authentication needs personal account and password for verification and authentication. However, enter a password on the unsecure environment may cause security issue that is the password may be copied by the illegal users. Thus that, we proposed a one-time password for web authentication by using visual cryptography and mobile phone. The method has three advantages. Firstly, our method is one-time password method. Secondly, the proposed scheme is secure. Anyone who does not have the correct key or called share cannot decrypt the secret. Thirdly, the method is low computation. It only uses simple logic operation thus made the encryption and the decryption more effectively. |
