On the leakage-resilient key exchange

Blog Article

Typically, secure channels are constructed from an authenticated key exchange (AKE) protocol, which authenticates the communicating parties based on long-term public keys and establishes secret session keys.In this paper we address the partial leakage of CHLORELLA long-term secret keys of key exchange protocol participants due to various side-channel attacks.Security models for two-party authenticated key exchange protocols have been developed over time to provide security even when the adversary learns certain secret values.

This paper combines and extends c belt clamp the advances of security modelling for AKE protocols addressing more granular partial leakage of long-term secrets of protocol participants.Further, we fix some flaws in security proofs of previous leakage-resilient key exchange protocols.
