A Novel Authentication Framework Using Negative Password Method for Improving Security

Abstract

Password storage is a critical angle in frameworks dependent on secret word verification, which is the most broadly utilized confirmation method. In this paper, we contemplated a secret key verification structure that is intended for secure secret phrase stockpiling and can be effortlessly utilized into existing validation frameworks. In this system, first, they got plain secret word from a customer is waded through a cryptographic hash work (SHA-256) and a plan dependent on MD5 calculation (for secret phrase stockpiling). Accordingly the hashed secret key is changed over into a negative secret key. At last, the negative secret word is scrambled into an Encrypted Negative Password (ENP) utilizing a symmetric-key calculation (AES) and multi-cycle encryption is utilized to enhance security. The cryptographic hash work and symmetric encryption make it hard to split passwords from ENPs. The calculation examination demonstrates that the ENP give more grounded secret phrase insurance under different assault. The ENP is the main secret key assurance conspires that consolidates the cryptographic hash work, the negative secret word and the symmetric-key calculation, without the requirement for extra data aside from the plain secret phrase.
