Abstract

Passwords are widely used to secure client–server communication in authentication-based systems that are used over untrusted transmission media; thus, users' passwords are vulnerable, and systems are vulnerable to hacking. In this paper, we propose a new philosophy for secret password encryption where encryption is secure between communicating parties during a communication session while ensuring resistance to man-in-the-middle attacks and preventing dictionary attacks in violation of trustworthiness without relying on trusted third parties or other out-of-band mechanisms for authentication, which will be encrypted on the basis of the data from the image sent during authentication. The proposed encryption scheme will encode each character of the password and replace it with a value representing the pixel value locations in the image and choose randomly. The sent image serves as the key to the algorithm used to encrypt the password after encrypting it with the same password. The proposed approach provides security, efficiency, reliability and cryptanalysis against various attacks. The proposed scheme has shown ability through several security analyses to resist man-in-the-middle attacks and reattacks. Finally, we compare the performance of our protocol with that of existing schemes. Hence, our system ensures good security and efficiency features.
