Cryptographic protocols based on public-key methods have been
traditionally based on certificates and Public Key Infrastructure (PKI) to
support certificate management. The emerging field of Identity-Based
Encryption (IBE) protocols allows simplification of infrastructure
requirements via a Private-Key Generator (PKG) while providing the
same flexibility. However, one significant limitation of
IBE methods is that the PKG can end up being a
de facto key escrow server, with undesirable consequences. Another
observed deficiency is a lack of mutual authentication of communicating
parties. This document specifies the Identity-Based Authenticated Key
Exchange (IBAKE) protocol. IBAKE does not suffer from the key escrow
problem and in addition provides mutual authentication as well as perfect
forward and backward secrecy. This document is not an Internet Standards
Track specification; it is published for informational purposes.
