SSLv3 remains the most implemented protocol. Private Communication Technology (PCT) Secure Sockets Layer SSL is built on top of TCP. TCP provides reliable packet delivery. Rogue packet problem: Maliciously introduced TCP packet. SSL disregards the package. TCP however will not accept the true packet, because it looks like a double to it. SSL will have to start over. Easy to do, since it only needs to satisfy the non cryptogr ...
