Physical layer security: secrecy performance analysis and design of cooperative communication systems
Security aspects of wireless networks have gained increasing interest in the field of communication security. Due to the nature of wireless networks potential security risks, vulnerabilities and threats are still a possibility, such as eavesdropping and denial of service attacks, which have been an …

SMARTPHONE-BASED COMPRESSION-INDUCED IMAGING SYSTEM DATA SECURITY
… we obtain tactile images, and we developed data security methodology in this thesis. The first version of the system (SCIS V1) is developed using the symmetric key encryption, which protects all medical data from hackers. AES (Advanced Encryption Standard) encryption method is used to protect the …

Integrated optical components for quantum key distribution
The security of current public key cryptosystems, such as RSA, depends on the difficulty of computing certain functions known as trapdoor functions. However, as computational resources become more abundant with the fast development of super- and quantum computers, relying on such methods for …

Holistic Security Engineering for Software-Defined Vehicles
… from cyberattacks by designing and implementing security concepts in the main phases of a vehicle's lifecycle. We use SAE level 4 prototype vehicles to evaluate our proposed techniques. We start with a systematic security requirement analysis using the ISA-62443 standard series, demonstrating how …
