Update of /cvsroot/devil-linux/build/scripts/configuration/help In directory sc8-pr-cvs12.sourceforge.net:/tmp/cvs-serv27437/scripts/configuration/help Added Files: pptp_mppe_mppc_patch.help Log Message: - added optional mppe-mppc patch for pptp --- NEW FILE: pptp_mppe_mppc_patch.help --- CONFIG_POPTOP_MPPE_MPPC MPPE stands for Microsoft Point-to-Point Encryption. It is a protocol designed for transfering encrypted datagrams over point-to-point links. See RFC3078 and RFC3079 for details. MPPE comes in Linux kernel by default. MPPC stands for Microsoft Point-to-Point Compression. It is a protocol designed for transfering compressed datagrams over point-to-point links. The MPPC algorithm uses an LZ based algorithm with a sliding window history buffer. See RFC2118 for details. Although the module's source code is completely free, MPPC itself is patented algorithm. Patent for *Microsoft* PPC is holded by the Hifn Inc. This is obvious ;-). Furthermore, MPPE uses RC4[1] encryption algorithm which itself isn't patented, but RC4 is trademark of RSA Data Security Inc. To avoid legal problems, US citizens shouldn't use this module. http://mppe-mppc.alphacron.de/ |
