Key-escrow resistant ID-based authentication scheme for IEEE 802.11s mesh networks

Nowadays, ID-based cryptography is reported as an alternative to Public Key Infrastructures (PKI). It proposes to derive the public key from the node´s identity directly. As such, there is no need for public key certifcates, and direct beneft of this is to remove the burdensome management of certifcates. However, the drawback is the need for a Private Key Generator (PKG) entity which can perform a key escrow attack. In this article, we present an ID-based authentication scheme that is adapted to the IEEE 802.11s mesh networks and resistant against key escrow attacks.
