DESCRIPTION:In pervasive computing environments\, communicating devices ar
 e often resource-constrained\, and bandwidth and connectivity may be limit
 ed as well. Bootstrapping key agreement via human-memorable passwords offe
 rs clear user-friendliness. Identity-based cryptography (IBC)\, first intr
 oduced by Shamir in 1984\, and made practical by schemes proposed by Boneh
  and Franklin in 2001\, offers certificateless operation. In this talk\, w
 e motivate the problem of inter-domain key agreement\, and present a solut
 ion which combines passwords and IBC\, conferring advantages such as being
  lightweight and PKI-free at the client side. We will also provide heurist
 ic analysis of the protocol's security.
