Abstract

The invention is a method and system for authentication. A central node for issuing certificates to a plurality of nodes associated with the central node in a network is also provided. The central node receives a first key from at least one node from among the plurality of nodes and generates a second key based on the received first key and generates a certificate for the at least one node. The generated certificate is transmitted to the at least one node.

Abstract

This invention addresses user cooperation in wireless networks implemented on the network protocol layer level, and attains a higher stable throughput and improved transmission delay. The cooperation is designed between a set of source user nodes transmitting to a common destination, where users with channels providing a higher successful delivery probability, in addition to their own traffic, relay packets of other source users whose transmissions to the destination fails.

Abstract

A method and apparatus for authenticating a biometric scanner involves estimating unique intrinsic characteristics of the scanner (scanner pattern), that are permanent over time, and can identify a scanner even among scanners of the same manufacturer and model. Image processing and analysis are used to extract a scanner pattern from images acquired with the scanner. The scanner pattern is used to verify whether the scanner that acquired a particular image is the same as the scanner that acquired one or several images during enrollment of the biometric information.

Abstract

An apparatus includes a function module, a strength module, and a filter module. The function module compares an input signal, which has a component, to a first delayed version of the input signal and a second delayed version of the input signal to produce a multi-dimensional model. The strength module calculates a strength of each extremum from a plurality of extrema of the multi-dimensional model based on a value of at least one opposite extremum of the multi-dimensional model.
