Well hi all Sorry I didn't got to introduce myself last time......as my system was down for a while......let me do it now... My name is Alex Ho, and i belong to the Internet Research & Development Unit (IRDU) in National University of Singapore. I am basically a analyst programmer who is specialising in network security. I have looked into matters on Firewalls(Network based and application based) and also encryption. My interest at the moment concerns on secure transaction on Internet. I have looked at PGP, DES, and will also be looking in SSL. Hoped to hear any advices for that..... Regards Alex
