There are newer stream ciphers, mostly due to eSTREAM: http://www.ecrypt.eu.org/stream/ I don't understand the rationale for stream ciphers today though. The traditional argument for stream ciphers was speed but you get 10GBps+ with nice modes like AES-GCM. Further, you can build a secure key stream generator from any secure block cipher (see for example [1]). Maybe the argument today is cost of hardware, but for that to be effective in the long run you have to beat Moore's law. /Simon [1] http://csrc.nist.gov/groups/ST/toolkit/BCM/documents/proposedmodes/kfb/kfb-spec.pdf _______________________________________________ nettle-bugs mailing list [email protected] http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs
