Title: SECURE AUTOMATIC CONFIGURATION METHOD OF MULTICAST ADDRESSES IN IPv6-BASED NODES IN NETWORK LAYER
Inventor: HONG YONG GEUN
IPC: H04L12/18
Filed: 2001-12-21
Abstract: PURPOSE: A method for automatically and stably allocating multicast addresses of an IPv6(Internet Protocol version 6)-based node in a network layer is provided to combine a lower 64-bit interface ID of link-local unicast addresses and side-local unicast addresses set in interfaces of every node with information acquired from a router, so as to automatically generate link-local multicast addresses and side-local multicast addresses in a host. CONSTITUTION: Each IPv6 node checks whether unicast addresses are set in interfaces(S10). If so, a packet delivery range of the unicast addresses is checked, if global, to return to the step S10 without additional processing(S20). If the packet delivery range indicates side-local, a 16-bit subnet ID and a 64-bit interface ID are extracted from the unicast addresses(S30,S40). If the packet delivery range indicates link-local, only the 64-bit interface ID is extracted from the unicast addresses(S30). Whether to provide a security function for the 64-bit interface ID extracted from the unicast addresses is checked(S50). If the security function is decided to be provided, the 64-bit interface ID is enciphered(S60). If the security function is decided not to be provided, and after enciphering the 64-bit interface ID, a 32-bit group ID is generated(S70). And obtained information is combined to generate link-local multicast addresses and side-local multicast addresses and store generated addresses according to interfaces on each node(S80), then the step S80 is returned.
