Phantom jam Sybil attack in connected vehicular networks
Vehicular Ad-hoc Networks (VANETs) are vulnerable to Sybil attacks, mostly due to the lack of encryption in BSMs. In VANETs, multiple digital certificates (pseudonyms) are assigned to each vehicle to ensure their privacy. However, malicious nodes can exploit these pseudonyms to create ghost …

Security in home IoT environments
This thesis investigates the overall security of home IoT environments and how to remediate most of the common security issues in IoT environments. The assumption is made that most IoT environments are poorly or lazily configured when it comes to security. The methods used to research the security …

The geo-secure system: a secure system for data access based on geographical data
"Computers have become a basic need for the majority of people around the world. Governments, companies, and individuals have a large number of sensitive information stored online; electronic transactions using these data becomes daily activities. Consequently, computer security has become a major …
