How to Provide MN-MAP Security? Authentication-only Mode In this mode, a MAP only needs to ensure that the same MN is sending the BUs to the MAP. It is not necessary for the MN to prove that it is authorized to use a MAP to manage its mobility. Cookie0 = {Src=LCoA, Des= MAP, Opt=HoA, C0} Cookie1 = {Src=MAP, Des=LCoA, Opt=HoA, C0, C1, N1}. BU1 = {Src=LCoA, Des=MAP, Opt=HoA, C0, C1, N1, N2, TS, SIGMN , CertMN}, SIGMN = Sig(SKMN, LCoA|HoA|MAP|N1|N2|TS). BA1 = {Src=MAP, Des=LCoA, Opt=HoA, RCoA, C0, C1, N1, N2}, BUi = {Src=LCoA, Des=MAP, Opt=HoA, old_LCoA, TS, SIGMN_i} SIGMN_i = Sig(SKMN, LCoA|MAP|HoA|old_LCoA|TS). BAi = {Src=MAP, Des=LCoA, Opt=HoA} |
