Transport-level encryption with Tcpcrypt By Jake Edge August 25, 2010 It has been said that the US National Security Agency (NSA) blocked the implementation of encryption in the TCP/IP protocol for the original ARPANET, because it wanted to be able to listen in on the traffic that crossed that early precursor to the internet. Since that time, we have been relegated to always sending clear-text packets via TCP/IP. Higher level application protocols (i.e. ssh, HTTPS, etc.) have enabled encryption for some traffic, but the vast majority of internet communication is still in the clear. The Tcpcrypt project is an attempt to change that, transparently, so that two conforming nodes can encrypt all of the data portion of any packets they exchange. <snip> http://tcpcrypt.org/ -- Sean McGrath s...@manybits.net --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com
