PC printer-port dongle security : demonstrated its vulnerability by
cracking it (Rainbow Technologies Sentinel) three times with different
methods: software-only, hardware-only
(built an identical dongle - new software releases run without modification) and combination hardware-
software (able to crack any new dongle).
My current interests are internet appliances, cryptography, internet alarm systems and image
I have 20 years experience in 3 different industries: semiconductor manufacturing, oil & gas utilities and
Semiconductor Manufacturing 1991 - present
Design of semiconductor assembly equipment. Completed projects are Philips Semiconductors BIM-2
series ie, parametric tester (PARSET 2), die-bonder(ADAT 2) and wire-bonder (PHICOM 2). BIM-2 uses innovative realtime Windows NT and CPLD in-system reconfigurable hardware towards a generic equipment model (GEM) architecture.
Also completed are 20+ units Hewlett Packard generic RF parametric testers for wafer probe and final test. Worked on three locations, in Seremban - Malaysia(ON Semiconductor/Motorola), Nijmegen - The Netherlands (Philips Semiconductors), and Penang - Malaysia (Hewlett Packard).
My specialty in HP was in EMC (Electromagnetic Compatibility), as per European Union directive.
The Philips BIM-2 line are high-speed reel-to-reel integrated manufacturing
systems running at a top
speed of 15K units per hour. The novelty here is the use of Windows NT for high-performance soft
realtime control work. I implemented realtime features in Windows NT necessary for the control program.
The HP Malaysia testers are specialised for microwave devices with a top speed of 6K units per hour.
They are built from ground-up with HP and local resources.
Utilities and Oil & Gas 1985 - 1990
Design, repair & commissioning of industrial electronic systems for the utilities(electrical, water and
mass transit), oil & gas installations (onshore & offshore flow measurement and platform remote control). Major projects were REE (Red Elektrika de Espana), Hongkong MRT, Bekok-C platform Flow Computers, Semangkok A & B platforms remote control.
Worked in two locations: Chippenham- UK (Westinghouse Systems Ltd) and offshore/onshore Kertih (Dectra).
I was also electronics field engineer (microwave survey & GPS systems) aboard the survey ship Teknik Samudra.
In Westinghouse I was among the 5 software designers responsible for
designing and maintaining
VAX 11/780 VMS C master programs for the other engineers to copy. I was responsible for the portion
that did front-end data gathering and hot-standby networked(DECnet) hosts.
In Dectra (an ESSO/Petronas subcontractor), I designed hot-standby and
monitoring flow computers that calculate oil & gas flow in pipelines
in realtime. This was done using Analog Devices MACSYM computer, IBM PC
compatibles and HP 9000 series 300. I also maintained old ESSO flow computers
including the Daniel
digital and analog flow computers.
Commercial Building Systems 1983 - 1988
Design and prototyping of building automation, fire alarm and security systems for commercial
buildings. Major project was Perangsang International building automation. Work done was in PJ
(Powermatics and Dectra).
At Dectra, I designed a local second-source for the original Microcontrol (Belgian) Tadpole system, and
rewrote the control software for the host computer, porting from PDP 11 and Ultrix to PC and SCO Xenix.
The hardware cost savings was 10X, and the software speed improved 4X.
