Anyone familiar with legal requirements for ISP data retention and common off-the shelf lawful interception products, does going connectionless protocol like UDP make things more difficult for Mallory, and buys Alice/Bob a few years more time until this potential loophole is closed?
Connectionless protocols havent been an issue for Mallory for years. While i am no longer working in the core, when I left, there were already a half dozen tools widely distributed that could pull of reconstruction of just about any defined protocol, connectionless, connection, or multiflow/multiconnection. Lawful intercept requirements are still a debated topic, however, when I left most was being done under an FBI Patriot Letter. Once in a great while you'd see another agency, but FBI is the primary Mallory of concern today: Draw your own conclusions as to what they can/cant do with caution though. They now know when they dont know, and demand assistance. //Alif -- Yours, J.A.
