Apparently few had problems downloading the PDF files from our (BIU) site. so I've put both papers in ecrypt (which I believe is more reliable), and also, I've put HTML version in our site.
So, I apologize for the inconvenience if you tried before and got nothing, but these links should work fine, and I am very interested in your feedback:
# Protecting (even) Na´ve Web Users, or: Preventing Spoofing and Establishing Credentials of Web Sites, at http://eprint.iacr.org/2004/155/ and http://www.cs.biu.ac.il/~herzbea/Papers/ecommerce/Spam.htm
# Controlling Spam by Secure Internet Content Selection, at http://eprint.iacr.org/2004/154/ and http://www.cs.biu.ac.il/~herzbea/Papers/ecommerce/Spam.htm
