Anti-continuous collisions user-based unpredictable iterative password salted hash encryption

Abstract

Recently, providing services remotely over a network to enhance functionality and usability has become a trend. Applications regularly contain sensitive and personal information that should be managed and controlled by authorised persons. Thus, keeping the password security is important to prevent unauthorised users from impersonating other legal users. Hashing the password is one of the safety methods and means of preventing attacks. In this study, we proposed an iterative salted hash encryption mechanism named anti-continuous collision salted hash encryption (ACCSHE) that uses cryptographically secure pseudo random number generator (CSPRNG) and hashed with password data by secured hashing algorithm (SHA-256). The outcome manifests a flexibility of changing the results by controlling several key features, such as salt used, the range of the hashing process iterations or the minimum number of iterations without affecting the system's usability. The system efficiently prevented continues collision issue and effective processing time cost for an attacker.
