In this Best Readings, we highlight overview articles, archival technical papers, as well as special issues on physical-layer security that are representative of physical-layer security today. While the list is far from exhaustive, the selected papers have been influential by identifying new problems, providing innovative and elegant solutions, pointing out important future directions, as well. Dec 15, 2018 D. Physical-Layer Key Generation Scheme. The key generation scheme exploits the physical randomness from the PMD effect of the optical fiber link to generate symmetric secret keys for Alice and Bob. Alice and Bob initiate the key generation mechanism by sending predefined probe signal (bit sequence) to each other. Of physical-layer identification of RFID transponders. We propose several techniques for the extraction of RFID physical-layer fingerprints. We show that RFID transponders can be accurately identified in a controlled environment based on stable fingerprints corresponding to their physical-layer properties. We tested our tech. Microsoft office word 2007 activation key generator.
Physical layer in the OSI model plays the role of interacting with actual hardware and signaling mechanism. Physical layer is the only layer of OSI network model which actually deals with the physical connectivity of two different stations. This layer defines the hardware equipment, cabling, wiring, frequencies, pulses used to represent binary signals etc.
Physical layer provides its services to Data-link layer. Data-link layer hands over frames to physical layer. Physical layer converts them to electrical pulses, which represent binary data.The binary data is then sent over the wired or wireless media.
Signals
When data is sent over physical medium, it needs to be first converted into electromagnetic signals. Data itself can be analog such as human voice, or digital such as file on the disk.Both analog and digital data can be represented in digital or analog signals.
Transmission Impairment
When signals travel through the medium they tend to deteriorate. This may have many reasons as given:
Transmission Media
The media over which the information between two computer systems is sent, called transmission media. Transmission media comes in two forms.
Channel Capacity
The speed of transmission of information is said to be the channel capacity. We count it as data rate in digital world. It depends on numerous factors such as:
Multiplexing
Multiplexing is a technique to mix and send multiple data streams over a single medium. This technique requires system hardware called multiplexer (MUX) for multiplexing the streams and sending them on a medium, and de-multiplexer (DMUX) which takes information from the medium and distributes to different destinations.
Switching![]()
Switching is a mechanism by which data/information sent from source towards destination which are not directly connected. Networks have interconnecting devices, which receives data from directly connected sources, stores data, analyze it and then forwards to the next interconnecting device closest to the destination.
Switching can be categorized as:
