2. Introduction  The authors' proposed  ID-based encryption provides end-to-end authentication  PKI-support approaches (RSA) 2008/08/292H.-H. Ou

3. The proposed  Initialization  Key generation center  Private key: d  Public Key: e  Node identity: ID i  ID’s Signature: g i = ID i d mod n 2008/08/293H.-H. Ou

4. The proposed 2008/08/294H.-H. Ou  Key agreement  Node i  Randomly select r i  Public keys (y i, t i ): y i = g i α ri mod n, t i = r i e mod n  T i is timestamp, s i = g i r i f(yi, ti, Ti, IDj ) mod n  (ID i, y i, t i, s i, T i )   Identity  S j e =? Id j t j f(yj, tj, Tj, IDi) mod n  Session key  SK i = (y j e / ID j ) ri mod n  SK i = α erirj mod p = SK j  Node j  Randomly select r j  Public keys (y j, t j ): y j = g j α rj mod n, t j = r j e mod n  T j is timestamp, s j = g j r j f(yj, tj, Tj, IDi ) mod n   (ID j, y j, t j, s j, T j )  Identity  S i e =? Id i t i f(yi, ti, Ti, IDj) mod n  Session key  SK j = (y i e / ID i ) rj mod n
