In 1996, I have started my professional carrier in a Belgian company called Digipass. One month after my beginning, this company was buy by an American Company called Vasco. Vasco Data Security was born. My first projects on R&D team was (at the beginning) mainly the development Interactive Voice Reponse System and after one year, i start to work on Digipass firmware ( Digipass 300 / 500/ 600/ 700 ). I have integrated and optimized some number of securites encryption algorithm, driver, etc… in assembler code on Samsung microchip KS56/57. (triple DES / Gardian…). I have also worked on DES/RSA card drivers on Unix and other tools who are used to initialized the Digipass products…
