Cryptographic Key Distribution In Wireless Sensor Networks Using Bilinear Pairings
… from traditional fixed networks, and standard cryptographic solutions cannot be used in this application space. Despite many research efforts, key distribution in WSNs still remains an open problem. Many of the proposed schemes suffer from high communication overhead and storage costs, low …

Cryptographic key distribution in wireless sensor networks: a hardware perspective
… suitability of different methods of symmetric key distribution for application in wireless sensor networks are discussed. Each method is considered in terms of its security implications for the network. It is concluded that an asymmetric scheme is the optimum choice for key distribution. In …

A prototype system for geo-based, cryptographically-enforced access control for miniature drones' video feeds
… geo-based access control and agile, dynamic key management. The system utilizes a Parrot AR Drone 2.0 to stream an encrypted video feed to a number of Android-based tablets. The tablets are able to decrypt the video feed only if they are authorized to access it, based on the drone's location …

An ICmetric based framework for secure end-to-end communication
Conventional cryptographic algorithms rely on highly sophisticated and well established algorithms to ensure security, while the cryptographic keys are kept secret. However, adversaries can attack the keys of a cryptosystem without targeting the algorithm. This dissertation aims to cover this gap …

Study of Physical Unclonable Functions at Low Voltage on FPGA
… like intellectual property, chip authentication, cryptographic key generation and trusted computing. Moreover, FPGA evolving as an important platform for flexible logic circuit, present an attractive medium for PUF implementation to ensure its security. In this thesis, we explore the behavior of …

Extending the analysis of the FlipIt game
… Such scenarios include targeted attacks, cryptographic key rotation, password changing policies and cloud auditing. What we are particularly interested in are situations in which an attacker repeatedly takes control over a system or critical resource completely, learns all its secret …

Key Management Scheme for Smart Grid
… vulnerabilities to be thoroughly investigated. Key management is one of the most important security requirements to achieve data confidentiality and integrity in a SG system. It is not practical to design a single key management scheme/framework for all systems, actors and segments in the smart …

VMIaaS: Virtual Machine Introspection as a Service
… world is becoming part of our daily lives. One key technology that becomes part of this digital transformation is cloud computing. It allows users to have a running system as a virtual machine (VM) on the cloud without owning a physical server. Unfortunately, adversaries can also use those …
