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 …

We introduce new tightly-secure authenticated key exchange (AKE) protocols that are
extremely efficient, yet have only a constant security loss and can be instantiated in the …

Abstract Authenticated Key Exchange (AKE) is a cryptographic protocol to share a common
session key among multiple parties. Usually, PKI-based AKE schemes are designed to …

Motivated by abstracting the common idea behind several implicitly authenticated key
exchange (AKE) protocols, we introduce a primitive that we call double-key key …

The security of digital signatures depends significantly on the signature key. Therefore, to
reduce the impact of leaked keys upon existing signatures and subsequent ones, a digital …

Forward secrecy (FS) is a central security requirement of authenticated key exchange (AKE).
Especially, strong FS (sFS) is desirable because it can guarantee security against a very …

Abstract Authenticated Key Exchange (AKE) is an important primitive in applied
cryptography. Previously several strong models of AKE were introduced, eg, CK, CK^++ …

Plurality of users share a common key while permitting dynamic member change and
computational complexity required for key exchange is reduced. The first key generation unit …

Authenticated Key Exchange (AKE) is a cryptographic protocol to share a common session
key among multiple parties. Usually, PKI-based AKE schemes are designed to guarantee …

Most recently, a variant of extended Canetti–Krawczyk model called as eCKw is introduced
to provide stronger security than previous eCK models. Namely eCKw models formulate a …
