RSS detectorLatency- and Bandwidth-Minimizing Optimal Failure Detectors
White Paper Multi-node failure detectors, where the detector is tasked with monitoring N other nodes, play a critical role in overlay networks and peer-to-peer systems. Failure detectors are fundamental building blocks in distributed systems. [11 Jul 2008]
Convergence Analysis of Iteratively Detected Time Hopping and DS-CDMA Ultrawide Bandwidth Systems by EXIT Charts
White Paper It is shown from an EXIT chart analysis that the multipath diversity can yield a larger area under the EXIT curve of the inner detector. This paper presents a novel analysis on the decoding convergence of Time Hopping (TH) and Direct Sequence (DS... [11 Jul 2008]
A Distributed Host-Based Worm Detection System
White Paper The properties of the host-based detectors may in fact be relatively poor in isolation but when taken collectively result in a high-quality distributed worm detector. This paper present a method for detecting large-scale worm attacks using only end... [05 Jul 2008]
Application Layer Intrusion Detection for SQL Injection
White Paper Moreover, it proposes a model for an anomalous SQL detector which observes the database traffic from the perspective of the database server itself. SQL injection attacks potentially affect all applications, especially web applications, that utilize... [03 Jul 2008]
Undermining an Anomaly-Based Intrusion Detection System Using Common Exploits
White Paper This paper shows how an adversary can craft an offensive mechanism that renders an anomaly-based intrusion detector blind to the presence of on-going, common attacks. It presents a method that identifies the weaknesses of an anomaly-based intrusion... [01 Jul 2008]
Towards Survivable Intrusion Detection System
White Paper Key components of SIDS include: a dual-functionality forward-ahead (DFFA) structure, backup communication paths, component recycling, system reconfiguration, and an anomaly detector. Intrusion Detection Systems (IDS) are increasingly a key part of... [30 Jun 2008]
All-Digital TX Frequency Synthesizer and Discrete-Time Receiver for Bluetooth Radio in 130-nm CMOS
White Paper The conventional RF frequency synthesizer architecture, based on the voltage-controlled oscillator and the phase/frequency detector and charge-pump combination, has been replaced with a digitally controlled oscillator and a time-to-digital... [16 May 2008]
The Weekly Round-Up: 09.05.08
Round-Up A lie detector test that has slashed benefit fraud by more than £330,000 is being rolled out in the UK. Benefit fraudsters beware. If you're trying to pull a swift one on the authorities you may find their "liar, liar, pants on fire" accusations... [09 May 2008]
Lie detectors to hunt out benefit cheats
News A lie detector test that has slashed benefit fraud by more than £330,000 is being rolled out in the UK. The Voice Risk Analyser (VRA) system will be piloted by another 15 councils following its success in seven areas of the country. [07 May 2008]
An Adaptive Anomaly Detector for Worm Detection
White Paper This paper presents an adaptive end-host anomaly detector where a supervised classifier trained as a traffic predictor is used to control a time-varying detection threshold. Training and testing it on real traffic traces collected from a number of... [11 Apr 2008]
Constrained Maximum-Likelihood Detection in CDMA
White Paper In contrast, the unconstrained ML problem can be solved quite easily and is known as the decorrelating detector. Such a design criterion leads to detector structures, which are ML under the constraint assumption. [10 Apr 2008]
Peter Cochrane's Blog: The one-box generation
Comment Payment is ensured by a tracking system linked to the TV sales process and by detector vans that patrol areas where houses fail to register. The homes of young people who don't have a TV licence receive a visit from the detector van people. [26 Mar 2008]
Developing a Real-Time IP-Based G3 Facsimile Relay Solution
White Paper As a solution the company implemented speech codecs, general telephony algorithms, DTMF Generator/Detector, Tone Detector (voiceband), Echo Canceller, and codecs. The company wanted to develop and implement a real-time IP-based G3 facsimile relay... [14 Jan 2008]
Top 10 government IT stories of the year
News Lie detector beats benefit fraud The year was dominated by stories about government-held personal data, whether that was ID information or what people choose to throw away. Undoubtedly, the fall-out from HM Revenue & Customs' loss of two discs... [19 Dec 2007]
Stories of the year
News Lie detector beats benefit fraud But one of the biggest stories of 2007 - and not just in the tech world - turned up in October when two password-protected CDs containing the records of 25 million child benefit recipients were sent unrecorded and... [14 Dec 2007]
