Efficient One-Round Key Exchange in the Standard Model
We consider one-round key exchange protocols secure in the standard model. The security analysis uses the powerful security model of Canetti and Krawczyk and a natural extension of it to the ID-based setting. It is shown how KEMs can be used in a generic way to obtain two different protocol designs with progressively stronger security guarantees. A detailed analysis of the performance of the pr...
متن کاملGeneric One Round Group Key Exchange in the Standard Model
Minimizing complexity of group key exchange (GKE) protocols is an important milestone towards their practical deployment. An interesting approach to achieve this goal is to simplify the design of GKE protocols by using generic building blocks. In this paper we investigate the possibility of founding GKE protocols based on a primitive called multi key encapsulation mechanism (mKEM) and describe ...
متن کاملStrongly Secure One-Round Group Authenticated Key Exchange in the Standard Model
One-round group authenticated key exchange (GAKE) protocols typically provide implicit authentication and appealing bandwidth efficiency. As a special case of GAKE – the pairingbased one-round tripartite authenticated key exchange (3AKE), recently gains much attention of research community due to its strong security. Several pairing-based one-round 3AKE protocols have recently been proposed to ...
متن کاملOne Round Group Key Exchange with Forward Security in the Standard Model
Constructing a one round group key exchange (GKE) protocol that provides forward secrecy is an open problem in the literature. In this paper, we investigate whether or not the security of one round GKE protocols can be enhanced with any form of forward secrecy without increasing the number of rounds. We apply the key evolving approach used for forward secure encryption/signature schemes and the...
متن کاملOne-Round Key Exchange with Strong Security: An Efficient and Generic Construction in the Standard Model
One-round authenticated key exchange (ORKE) is an established research area, with many prominent protocol constructions like HMQV (Krawczyk, CRYPTO 2005) and Naxos (La Macchia et al., ProvSec 2007), and many slightly different, strong security models. Most constructions combine ephemeral and static Diffie-Hellman Key Exchange (DHKE), in a manner often closely tied to the underlying security mod...
