초록

IPv6 is newly introduced to solve limitations and problems of IPv4 and in IPv6 network, nodes use Neighbor Discovery protocol to discover the subnet prefix and configure its own address. However, Neighbor Discovery is vulnerable to various attacks as it does not have secure mechanism to protect itself. Thus, the Secure Neighbor Discovery has introduced and the main mechanism used in Secure Neighbor Discovery is Cryptographically Generated Address. In this paper, we provide a brief of Cryptographically Generated Address and its limitation in a case where a mobile node moves from one network to another frequently. The proposed scheme resolves this limitation by using the fixed interface identifier.
