The first edition of this book was published in 2003. Inevitably, certain parts of the book
became outdated quickly. At the same time new developments have continued apace …

An unresolved problem in research on authenticated key exchange (AKE) in the public-key
setting is to construct a secure protocol against advanced attacks such as key compromise …

Two-party key exchange (2PKE) protocols have been rigorously analyzed under various
models considering different adversarial actions. However, the analysis of group key …

We introduce the concept of attribute-based authenticated key exchange (AB-AKE) within
the framework of ciphertext-policy attribute-based systems. A notion of AKE-security for AB …

Broadcast encryption (BE) schemes allow a sender to securely broadcast to any subset of
members but requires a trusted party to distribute decryption keys. Group key agreement …

A recent primitive known as asymmetric group key agreement (AGKA) allows a group of
users to negotiate a common encryption key which is accessible to any entities and …

This paper proposes two one-round authenticated group key exchange protocols from newly
employed cryptographic invariant maps (CIMs): one is secure in the quantum random oracle …

In asymmetric group key agreement (ASGKA) protocols, a group of users establish a
common encryption key which is publicly accessible and compute pairwise different …

The scope of this paper is to review and evaluate all constant round Group Key Agreement
(GKA) protocols proposed so far in the literature. We have gathered all GKA protocols that …

This paper studies Tripartite Key Exchange (3KE) which is a special case of Group Key
Exchange. Though general one-round GKE satisfying advanced security properties such as …
