High Quality Content by WIKIPEDIA articles! Obfuscated TCP is a transport layer protocol which implements opportunistic encryption over TCP. It is designed to prevent mass wiretapping and malicious corruption of TCP traffic on the internet, with lower implementation cost and complexity than TLS. ObsTCP was created by Adam Langley, a former Maths and Computing student and systems administrator at Imperial College London, currently an employee of Google in California. The concept of obfuscating TCP communications using opportunistic encryption evolved through several iterations. The experimental iterations of ObsTCP used TCP options in 'SYN' packets to advertise support for ObsTCP, the server responding with a public key in the 'SYNACK'. An IETF draft protocol was first published in July 2008. Packets were encrypted with Salsa20/8, and signed packets with MD5 checksums.
