Lee, Han, and Kim reply.

In Letter [1], we reported our finding on the physical origin of wide band-gap opening in planar nanostrips, as derived by application of periodic width modulations in the magnetic waveguides. K. Di et al. in their Comment[2], however, argued that the band gap can be reduced remarkably by applying a linear combination of symmetric and antisymmetric fields (see 'A+B' in the inset of Fig. 1(a)). ...

Revisiting Lee, Kim, & Yoo Authenticated Key Agreement Protocol

In recent issue of Journal of Applied Mathematics and Computation (2005), Lee, Kim, & Yoo revealed an attack on Hsu, Wu, & Wu (2003) authenticated key agreement protocol, and then presented an improved protocol. However, Lee, Kim, & Yoo (2005) present only heuristic argument with no formal proof of security. In this work, we revealed previously unpublished flaw in the protocol. We may speculate...

Cryptanalysis of Lee-Kim-Yoo password-based key agreement scheme

Recently, Lee et al. [S.W. Lee, H.S. Kim, K.Y. Yoo, Improvement of Lee and Lee s authenticated key agreement scheme, Appl. Math. Comput., in press] showed that Lee–Lee password-based authenticated key agreement scheme [N.Y. Lee, M.F. Lee, Further improvement on the modified authenticated key agreement scheme, Appl. Math. Comput. 157 (2004) 729–733] is vulnerable to an off-line dictionary attack...

On the Security of Lee, Kim, Kim, & Oh Key Agreement Protocol

In ICCSA 2005, Lee, Kim, Kim, & Oh proposed a new (two-party) ID-based key agreement protocol, which they claimed to provide known key security resilience, forward secrecy, key compromise resilience, unknown key share resilience, and key control, however, without providing any security proofs. In this work, we demonstrate that their claims of known key security resilience and key control are fl...
