Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

ABSTRACT

Jammer are the device by which we can creat a temporary “dead zone”in there immediate proxcimity.
There are three type of jammer .
Radar jammer
Radio jammer
Cell phone jammer

A cell phone jammer is an instrument used to prevent cellular phones from receiving and transmitting the mobile signals to a base station. When used, the jammer effectively disables cellular phones in the area.

Jamming basics

Abstract
This report presents the design, implementation, and testing of a dual-band cell-phone jammer. This jammer works at GSM 900 and GSM 1800 simultaneously and thus jams the three well-known carriers in Jordan (Zain, Orange, and Umniah). This project went through two phases:
Phase one: studying the GSM-system to find the best jamming technique, establishing the system d ....etc

Abstract:

Cell phones and radio receivers are used everywhere these days. It's great to be able to call anyone anytime. But unfortunately, restaurants, movie theatres, concerts, shopping malls and churches all suffer from the spread of cell phones because not all cell-phone users know when to stop talking. While most of us just grumble and move on, some people are actually going to extremes to retaliate. FM Jammer can be one of the ....etc

The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc
