Cryptanalysis for Secure and Efficient Smart-Card-Based Remote User Authentication Scheme for Multi-server Environment
Multi-server authentication is going to be an integral part of remote authentication with the passage of time. The remote authentication has been part and parcel of internet based communication. In the last decade several multi-server authentication techniques has been presented. However there is still a need of more efficient and robust techniques. Lately, Saraswathi et al., presented a multi-server authentication scheme that has been found under much vulnerability like stolen card attack, misrepresentation attack, and forward secrecy attacks. This paper presents the cryptanalysis for Saraswathi et al. scheme and shows the review analysis
A secure lightweight authentication mechanism for IoT devices in generic domain
The Internet of Things prompt deployment enhances the security concerns of these systems in recent years. The enormous exchange of sensory information between devices raises the necessity for a secure authentication scheme for Internet of Things devices. Despite many proposed schemes, providing authenticated and secure communication for Internet of Things devices is still an open issue. This research addresses challenges pertaining to the Internet of Things authentication, verification, and communication, and proposes a new secure lightweight mechanism for Internet of Things devices in the generic domain. The proposed authentication method utilizes environmental variables obtained by sensors to allow the system to identify genuine devices and reject anomalous connections
A Survey on Wireless Sensor Network Security
Wireless sensor networks (WSNs) have recently attracted a lot of interest in
the research community due their wide range of applications. Due to distributed
nature of these networks and their deployment in remote areas, these networks
are vulnerable to numerous security threats that can adversely affect their
proper functioning. This problem is more critical if the network is deployed
for some mission-critical applications such as in a tactical battlefield.
Random failure of nodes is also very likely in real-life deployment scenarios.
Due to resource constraints in the sensor nodes, traditional security
mechanisms with large overhead of computation and communication are infeasible
in WSNs. Security in sensor networks is, therefore, a particularly challenging
task. This paper discusses the current state of the art in security mechanisms
for WSNs. Various types of attacks are discussed and their countermeasures
presented. A brief discussion on the future direction of research in WSN
security is also included.Comment: 24 pages, 4 figures, 2 table
