A dynamic trust and mutual authentication scheme for MANET security
… a few. This research proposes a two-phase scheme. In phase-one a novel approach is suggested by using concept of exiting trust schemes and adopting the use of Dynamic Trust Threshold Scheme (DTTS) for the selection of trusted nodes in the network and using mutual trust acknowledgement …

Key-Based Authentication Scheme for eVTOL Drones Using Chebyshev Chaotic Maps
… attacks. This paper proposes a key-based authentication scheme that utilizes Chebyshev polynomials as chaotic maps, hash functions, and the AES-256 encryption technique. The network members can securely generate all encryption keys without sharing secret data, which solves one of the main …

PRIVACY-AWARE AND HARDWARE-BASED ACCLERATION AUTHENTICATION SCHEME FOR INTERNET OF DRONES
… to do those types of things. However, without an authentication system in place anyone could gain access or control to real time data to multiple drones within an area. This is a problem that I choose to tackle using a Field Programmable Gate Array (FPGA) that accelerates the k-Nearest Neighbor …

It is I: An Authentication System for a Reconfigurable Radio
… a user. This work proposes a two-factor authentication scheme using a token and a biometric. The users' access rights are determined during authentication and the users are served only those channels of data that they are privileged to receive. The strengths and the weaknesses of the …

Transmitter Authentication in Dynamic Spectrum Sharing
… such threats is to employ a transmitter authentication scheme at the physical (PHY) layer. In PHY-layer authentication, an authentication signal is generated by the transmitter, and embedded into the message signal. This enables a regulatory enforcement entity to extract the …

Improving Routing Security Using a Decentralized Public Key Distribution Algorithm
… to OSPF containing a decentralized certificate authentication scheme (DecentCA) that eliminates the single point of failure/attack present in current OSPF security extensions. An analysis of the security of the DecentCA is performed. Furthermore, an implementation of DecentCA in the Quagga …

Bend Passwords: Using Gestures to Authenticate on Flexible Devices
… allowing us to explore new forms of user authentication. On flexible displays, users interact with the device by deforming the surface of the display through bending. In this thesis, we present a new type of user authentication that uses bend gestures as its input modality. We ran three …

Location Based Authentication
… of a genuine user. Today's conventional authentication mechanisms are based on three factors: knowledge, possession and biometrics. These factors are prone to theft, hardware failure, expensive, etc. Consequently, there is a need of a stronger solution. One such solution is Location Based …

Username and password verification through keystroke dynamics
… passwords as a mechanism for access control and authentication of authorized users. These credential sets offer marginal protection to a broad scope of applications with differing levels of sensitivity. Traditional physiological biometric systems such as fingerprint, face, and iris recognition …

Security and Privacy Schemes for Demand Response in Smart Grids
… Smart Grids. In this thesis, three cryptographic schemes are constructed for different demand-response programs. In the mandatory incentive-based demand-response program, privacy preservation depends on the power consumption of consumers. An anonymous authentication scheme is constructed for …

A system for multi-level authentication with physically unclonable functions
… Our proposed system uses a multi-level authentication scheme and employs different designs of PUF to achieve high security with low computational complexity and small footprint. By employing role-specific PUF designs, SoP reduces the area over existing PUF-based authentication solutions …

Authenticated messages for a real-time fault-tolerant computer system
This thesis develops a message authentication scheme for a new version of the X-38 Fault-Tolerant Parallel Processor (FTPP), a high-performance real-time computer system designed for applications that need extreme reliability, such as control for human spaceflight. This computer system uses …

Strategies and applications for creating more memorable passwords
… we deepen our understanding of the importance of authentication. There are many different types of authentication, each exhibiting their own strengths and weaknesses. Each authentication mechanism serves the same purpose: to verify a user’s identity. In this thesis, we explore two authentication …

Systems and models for secure fallback authentication
Fallback authentication (FA) techniques such as security questions, Email resets, and SMS resets have significant security flaws that easily undermine the primary method of authentication. Security questions have been shown to be often guessable. Email resets assume a secure channel of …

A novel authentication protocol based on biometric and identity-based cryptography
… and functionality. Developing a secure authentication protocol can be challenging; this thesis proposes an authentication scheme that employs two authentication factors involving something you know (password) and something you are (biometric) based on Identity-Based Cryptography and …

A contextual authentication framework for smart home environments
… are used in attacks. A number of cryptographic schemes have been proposed for securing communication among home IoT devices. However, the ability to handle such schemes, especially by devices with constrained computing resources, can be challenging. To address the above issues, this thesis …

Handoff Management Schemes in Wireless Mesh Networks
… presents our research work on handoff management schemes in traditional WMNs. In general, a handoff process includes two parts, the MAC layer handoff and the network layer handoff. For the MAC layer handoff, a self-configured handoff scheme with dynamic adaptation is presented. Before the mobile …

A spatio-temporal approach to mitigate automotive radar spoofing attacks
… random signals for physical challenge-response authentication. Though this approach immensely enhances the capability of identifying the sensor attacks, it fails to provide any recovery mechanism to the system. Recent work like Dutta et al., 2017 tries to address this by introducing recursive …

Towards Zero Trust Network Security via Programmable Data Planes
… to enable in-network fine-grained continuous authentication to grant network access to authorized processes. For this, we design NetCap, a novel continuous authentication scheme to validate every network access request and prevent attackers from stealing access tokens to gain unauthorized …

Runtime Detection of Hardware Trojan in Untrusted Network-on-Chip
… packet data. Both attacks can be tackled by the authentication. But unlike the software level authentication designs in the traditional networking system, the authentication in NoC has on-chip overhead issues. The thesis investigates three designs: one for packet hijacking attack detection, one …
