  1. XTR algorithm for MIKEY draft-liang-msec-mikey-xtr-00.txt Jing Liang Hui Deng Shouwen Lai

  2. Problem and Goal • RFC3830 uses Diffie-Hellman to establish group secure key • Performance is not good enough in application of mobile computing devices such as PDA. • Our draft is targeted to this problem and we proposed the method of applying XTR for MIKEY.

  3. Performance XTR : Efficient and CompactSubgroup Trace Representation Pentium III 450 MHz and 96 MB of Ram

  4. XTR-DH message Exchange INITIATORRESPONDER I_MESSAGE = HDR, T, RAND, [IDi|CERTi], [IDr], {SP}, XTR-DHi, SIGNi ----> R_MESSAGE = <---- HDR, T, [IDr|CERTr], IDi, XTR-DHr, SIGNr 1.Trace(ga) 3.Both parties computes key Trace(gab) 2.Trace(gb)

  5. Work Item? • Efficient Multicast Group Key Generation for the smart and resource-constrained device should be a problem ?
