ppose you want to visit a controversial web site (for example, a political activist site) and you (1) don’t want to reveal your IP address to the Web site, (2) don’t want your local ISP (which may be your home or office ISP) to know that you are visiting the site, and (3) you don’t want your local ISP to see the data you are exchanging with the site. If you use the traditional approach of connecting directly to the Web site without any encryption, you fail on all three counts. Even if you use SSL, you fail on the first two counts: Your source IP address is presented to the web site in every datagram you send; and the destination address of every packet you send can easily be sniffed by your local ISP. To obtain privacy and anonymity, you can instead use a combination of a trusted proxy server and SSL. With this approach, you first make an SSL connection to the trusted proxy. You then send, into this SSL connection, an HTTP request for a page at the desired site. When the proxy receives the SSL-encrypted HTTP request, it decrypts the request and forwards the cleartext HTTP request to the web site. The web site then responds to the proxy, which in turn forwards the response to you over SSL. Because the web site only sees the IP address of the proxy, and not of your client’s address, you are indeed obtaining anonymous access to the web site”. In your opinion, is this approach ethical?
