Title: Method of Replay Protection by Using Challenge in Mobile IP Service
Inventor: HA JEONG RAK
IPC: H04L12/22
Filed: 2001-08-27
Abstract: PURPOSE: A method for preventing an attack by message reuse using a challenge in a mobile IP(Internet Protocol) network is provided to allow an FA(Foreign Agent) providing a mobile IP service to deliver the random number challenge to mobile nodes, and to reject an IP network registration request from mobile nodes not including the challenge, so as to prevent a replay attack. CONSTITUTION: An FA delivers a challenge to a mobile node and receives a mobile IP registration request message from the mobile node(601). Whether a challenge information field is included is checked(602). If not included, the request is inappropriate and has errors(609,620). And if included, a challenge value(Chgx) of the challenge information field is compared with a challenge field value(603) to check over whether two values are equal(604). If equal and a flag field indicates 'INUSE'(609), replay is decided(610) and error processing is performed(620). If equal and the flag field does not indicate 'INUSE'(609), the request is legal(630). And if not equal, the challenge value(Chgx) is compared with an early challenge field value(605) to check over whether two values are equal(606). If equal and a flag field includes 'EARLY'(611), the challenge value(Chgx) is inserted in the challenge field(608) and the request is legal(630). If equal and the flag field does not include 'EARLY'(611), the request has an unknown challenge and errors(613,620). If the challenge value(Chgx) is not equal to the challenge field and the early challenge field, whether the challenge value(Chgx) is included in challenge fields in a challenge window is checked(607). If not, the request has an unknown challenge and errors(613,620), and if included, the challenge value(Chgx) is inserted in the challenge field(608) and the request is legal(630). The mobile IP registration request is transmitted to a home agent(615) and a registration response message is received(616). And the flag field is changed to 'INUSE'(617) and the registration response message is transmitted to the mobile node(618).
