RETRACTION: Cryptanalysis and enhancement of multi factor remote user authentication scheme based on signcryption

Abstract

The major need of remote user authentication is to verify the authenticity of the user through insecure channel. Till today enormous remote user authentication schemes have been proposed but still some security flaws remains. Some of them are vulnerable to password guessing attack, Id guessing attack, client and server impersonation attack, replay attack, Denial of Service (DoS) attack etc. Besides the security issues many such schemes are supposed to have higher computational and communicational cost. To overcome these challenges a lightweight cryptographic scheme called signcryption has evolved. Signcryption is a logical combination of encryption and digital signature in single step. Thereby it provides necessary security features in less computational cost of 0.97 ms and communication cost of 824 bits. The proposed research work outlines the weakness in Dharminder et al's authentication scheme which is prone to biometric recognition error, offline password guessing attack, impersonation attack and replay attack. Furthermore the proposed study provides a secure multifactor authentication scheme using signcryption based on Hyper Elliptic Curve Cryptography (HECC) and Bio-hash function. The formal security analysis of proposed scheme is done using Burrows-Abadi-Needham logic. The analysis reveals that the proposed scheme is computational and communication efficient and satisfies all the needed security goals. The scheme is also been formally verified using AVISPA tool that confirms that it is resilient to security attacks.

A futuristic approach to generate random bit sequence using dynamic perturbed chaotic system

“…The speed analysis of our system was compared with existing systems and shown to have a 5% improvement in speed. All these analyses make the DPLM-PRNG more suitable for cryptographic applications like in bio-hash [29], remote-user authentication [30], steganography, encryption [31,32], etc.…”

Enhanced WSN Routing Protocol for Internet of Things to Process Multimedia Big Data

“…To achieve this proposed protocol is mainly designed to transmit data and information sensor nodes and varied wireless network nodes in emergency and disaster conditions. In this approach, every node connects to a sensor network based on spatial clusters and shares information on certain cluster nodes, or forwards data to each node whenever a node with such a high likelihood of data being sent to the destination is sometimes encountered [24].…”
